Attention! High-quality counterfeit bills look so real
The serial numbers on this bunch of new high-quality bogus RMB 100 banknotes
are LN37638309, LN37638313 and LN37638302. Police seized 30,000 yuan worth of
high-quality counterfeit 100 yuan notes in Guigang city, Guangxi Zhuang
autonomous region, South China. It's difficult to tell these fake notes from
real ones as they carry water marks, metal wires and a number of other
anti-counterfeit features. [Xinhua]
According to CCI, in 2011 contton imports may go up
BEIJING - Prompted by booming domestic consumption, China may import more
cotton from the United States this year, said Karin Malmstrom, China director of
Cotton Council International (CCI), the export promotion unit of the US National
Cotton Council.
'According to one of our surveys, we are seeing a growing middle-class in
China that is willing to pay more for cotton,' Malmstrom said during a
promotional campaign on Tuesday.
'We are very optimistic about China's retail market,' she added.
As the world's largest buyer of cotton and soybeans, China has replaced
Canada as the largest export market for US agricultural products, according to a
report released by the US Department of Agriculture (USDA) earlier this
month.
China bought 996,100 bales of cotton from the US two weeks ago, the largest
weekly purchase in eight years, according to data from the USDA.
During the first nine months of the year, global cotton imports to China
declined to 1.9 million tons, a fall of 9.7 percent year-on-year, according to
data from China's General Administration of Customs. About half of those imports
came from the US, according to Malmstrom.
'With the recent large purchase, the import market share for US cotton is
expected to further expand,' she said.
In reality, things may not be so straightforward. China's cotton imports
depend largely on the health of its textile industry. More than 40 percent of
China's cotton imports are re-exported as textile products every year, according
to industry analysts.
And as the developed economies struggle with debt crises and high rates of
unemployment, 'Chinese textile companies are not very optimistic about the
export market', said Gao Fang, executive vice-president of the China Cotton
Association (CCA).
'In addition, China had a bumper cotton harvest this year, so it remains
uncertain whether imports from the US will increase,' Gao added.
Ma Wenfeng, a senior analyst at Beijing Orient Agribusiness Consultant Ltd,
said the volume of cotton imports this year is likely to remain unchanged from
last year.
'The price of cotton in the global market will remain stable for the time
being, thanks to the worldwide harvest,' he said.
China's cotton harvest this year is expected to jump by 9.3 percent from last
year to 7.28 million tons, according to a CCA forecast in October.
In October, China imported 252,000 tons of cotton, practically unchanged from
September, according to a statement on the CCA website.
The elevator for mining industry - bucket elevator, how to maintain and overhaul
To ensure bucket elevatorbe sustained, operation, we must do preventive
maintenance and overhaul plan of equipment well, and discover in time and
eliminate hidden dangers of accidents. Preventive maintenance plan is prevention
system of inspection, maintenance and repair for the lifting equipment

Top trend: Information technology applys to manufacturing industry
Manufacturing information on the mechanical role in promoting industrial
development largely reflected in the four levels. First, products, information
technology, and through the integration of advanced manufacturing technology,
the traditional mechanical products into information, computer, laser and other
high-tech, making mechanical and electrical integration products, integrated
products of modern technology, enabling product enhancements , raise the level
of intelligence to meet the information age requirements of mechanical products;
Second, the design, manufacturing process automation and intelligence, greatly
shorten the design cycle, improve the success rate of design, design costs,
faster market response, the manufacturing process automation, intelligent and
improve product quality and consistency, labor strength reduction; Third, at the
enterprise level, the company's various information integration, the formation
of the sharing of resources, improve enterprise management level, efficiency,
economic efficiency, thereby enhancing the market competitiveness of
enterprises; Fourth, enterprises realize the interconnection of information, so
that shared resources of different enterprises, dramatically changing the
machinery of industrial organization, development, production and business
model, reduce duplication and waste of resources to adapt to economic
globalization and the Internet of the requirements, and enhance the overall
competitiveness of the industry.
Information to the organizational structure of manufacturing enterprises may
be a straight line from the original functions of the system into a flat pyramid
organization of the network organization. Such as manufacturing, jaw crusher, ball mill energy has
entered the information mode of production, greatly improved its functionality
and usability, and mining machinery manufacturing industry to meet its
needs.Planned economic system, is a manufacturing company is only responsible
for the production of basic economic organization, but also a 'large', 'small'
mode of production, business and even assumed the social functions, R & D
capabilities weak, sales sectors of the weak, and relatively large processing
capacity, organizational structure, like olives, two small, the middle. In a
market economy, enterprises have become the main market, the need to strengthen
research and development and sales management, and the middle part of the
processing can take advantage of the processing capacity of the community,
organizational structure, such as dumbbells, two strong, the middle sperm.
Information to the organizational structure from the 'olive' to 'dumbbell'
change is possible.
Information technology also enables manufacturers to a fundamental change in
production mode. Lean and agile manufacturing, concurrent engineering, mass
customization, and so the endless mode of production, there were the result of
birth information. E-commerce, supply chain management, manufacturing and so the
network can not do without information technology, it is also the information
associated with the new production organization to continuously improve the
competitiveness of the manufacturing sector, rising to a new level, can continue
to meet the user's individual requirements.
Facing different environment, different technology developed for manufacturing
With scientific and technological development, especially in electronics,
information technology, rapid development, more and more high-tech applied to
the machinery manufacturing industry. Especially in recent years in China has
become our familiar word, but, in China almost become synonymous with poor
quality products, which can be seen that our product quality to be improved,
which depends largely on the our manufacturing process. Industrial countries
over a wide range of high-precision machining, precision machining,
micro-machining, micro-mechanical and micro / nano technology, laser processing
technology, electromagnetic processing technology, super-plastic composite
processing technology and processing technology and other new processing
methods.
High dependence on foreign technology , resulting in the development of
China's machinery manufacturing industry, controlled by others. China's
dependence on foreign technology up to 50%, while the United States, Japan is
about 5%, the ratio in developed countries are generally below 30%. And
self-sufficiency rate of China's key technologies, representing about 40% of
investment in fixed assets investment in equipment, there are more than 60% rely
on imports to meet, the key high-tech equipment is basically dependent on
imports. Especially since the reform and opening up, more and more foreign
companies to invest in China, China has introduced a number of foreign advanced
equipment but did not grasp the core technology. The industry believes that
China's machinery industry, there is a huge technological 'black hole', the most
prominent manifestations of the high dependence on foreign technology.
China's mining machinery manufacturing industry for many years, and now use
their own design 'heart' a little, and it makes a lot of mining machinery
industry whom trouble. But now there are several mining machinery manufacturing
enterprises started to pay attention to design their own main brand products. It
is noteworthy that many key areas, especially outside the field of defense
technology dependent, would pose a serious challenge to national security. As a
national high-tech Industrial Development Zone window, there is 57% of
technology from abroad. The industry generally believes that technology is state
of black hole formation and the degree of emphasis put into closely related.
Countries in the past two decades ignored the development of machinery industry,
policy, and funding has gone wrong. The most typical example is the state-owned
enterprises. State-owned enterprises on the creative talents of the property is
basically no incentive to implement, and property rights stimulate innovation
and R & D system is an important guarantee for the product. R & D
technologies and products, or taken away without compensation by the state,
either free copy by other companies. Take the example of China's mining
machinery manufacturing industry.
Eying on mining machinery, striving for further improvements
Gravel equipment mainly refers to the jaw crusher machine,
stone-breaking counter-type machine, cone crusher stone machine, impact crusher, sand making machine, vibrating screen, feeder and

The Killer of Coal Gangue pollution - Hongxing Coal Gangue crushers
Along with the national environmental protection law enforcement increasing,
people rise requirement of the environment quality. The issue of solving the
environment pollution caused by Coal Gangue is becoming more and more serious.
Gangue power is to make full use of the efficient heat ingredient of Gangue,
turning waste to wealth. It's the efficient way to slove the problem. Good-
perform coal gangue crusher is with low fineness output, low noise, energy
saving, convenient to use, etc. It well effects hard, dry and wet material. It

Movable crushing station Long Battle Out for Green Ecological
Mining 13ed September, National large-scale modernized coal preparation plant
company set up sit-meeting in Yinchuan city, Ningxia. This is the first
professional meeting in washing&separating processing hold by coal field in
the latest 10 years. It will widely summarize experience from large-scale
modernized coal preparation company, and improve coal producing and the way of
using. In this way, it will set up a ecological green mining concept of coal
mining and construction. Vigorously develop coal washing and processing, promote
cleaning and high efficiency using of coal and energy conservation and emission
reduction.
In order to promote coal washing and crushing going smoothly, increase
production of coal crushing and improve implement of energy conservation and
emission reduction, Henan Hongxing Machinery developed large scale coal
separating, washing and crushing equipment. Large scale jaw crusher and mobile crusher in coal crushing
and separating are with advanced technology, high efficiency, and environmental
protection. Environment worsening day by day and waste of mess, those caused by
mining is an issue now. It not only damages environment, but cannot make full
use of the mineral resource.
Along with the growth of coal preparing scale, the developing on high coal
ash, high sulfur coal, low coat coal, especially brown coal becomes much more
serious. It needs separator adn processing equipments more and more urgently.
Related technology and equipments develop so slow that is cannot meet the demand
of development. Hongxing Machinery Mobile Crusher makes benefit in making full
use of mineral resource, especially in coal preparation. Integration plant work
in a mine as a whole. Large scale jaw crusher, impact crusher, cone crusher, feeder,
vibrating screen, etc work
independently. At the same time deal with the waste in processing, effectively
reduce the damage of environment pollution.
Knowledge about Ball mill operation and solution 1
What you need to do when the ball mill enters the belly
bulge?
Ball mills are crucial
equipment for grinding after materials are crushed. It is an efficient tool for
grinding various materials into powder.
With regard to the use of Ball Mill belly bulge appeared in the process,
there are several factors:
Firstly, to see whether the ball mill to the mine mouth spit normally
expected, if not properly spit expected, is likely to lead to bulging belly ball
mill;
Secondly, listen to the sound of the ball mill; if the smaller changes the
sound stuffy, it is very possible to be ball bulging belly;
Then, look at the current ball mill control cabinet, so they think that when
the current value is likely to become larger mill expansion belly of the
precursor is in fact not the case, if the ball bulging belly, its current value
is become small. So we need to pay more attention to operating the ball mill
correctly.
Reason for blowing wind when using the cement mill
By blowing wind into the mill, the tiny powder can be blew away,
over-grinding can be reduced and bringing the buffering effect, the steam in the
mill can be removed, the blocking of the hole can be avoided and the sticking
among balls can be reduced.
The temperature of the mill and raw material can be reduced, which will
benefit the operating of the mill and the quality of the cement.
Benefit the environment, reduce the wearing out of the equipment.
Grate type Ball Mill has a
grid plate at the discharging end which has many holes for putting minerals
pulps out easily. At the discharging end where the grid plate is close to, it is
equipped with lifting device for mineral pulps which is radial shape strips.
These strips divide the area between grid plate and the end cover into several
fan-shape chambers, which lead to the hollow shaft. When a ball mill runs, these
strips function as lifting the pulps that is, lifting the mineral pulps up to
the hollow shaft through the hole on the grid plate. And then the pulps is sent
out of the ball mill through hollow shaft. In a word, this type has the
characteristics of discharging the mineral pulps by force and of high production
ability.
This type of ball mill is usually applied in the first-period of grinding
operation and it can get a higher capacity. But, its output product the size is
bigger than that of an overflow type ball mill.
Mastering the role of lubrication oil when running a ball mill
1) It could reduce the abrasion of the gear and other parts,and extend the
service life of the gear.
2) The lubrication oil could reduce the friction,and slow down the loss of
power and energy.
3) To some extent,it could spread the heat and has a certain cooling
effect.
4) Obviously,it could prevent the parts from corrosion and rust and reduced
noise, vibration and gear to reduce the impact of inter-role.
5) The lubrication oil could reduce the noise during the operation,and
lighten the vibration between the gear and the machinery.
6) Of course,it could wash dirt, clean the dust on the surface and reduce
wear and abrasion of the parts.
So the ball mill
operation is related to the lubrication.Rotating part is one of the important
components of ball mill.Drives motor, reducer and the gear drove the cylinder
and rotated together to grind the various materials.Good lubrication could
reduce the abrasion and extend the life of machinery.
New type jaw
crushers are also called high efficiency energy-saving fine jaw crushers which are
designed and manufactured by Zhongke Engineering Technology Co., Ltd for nearly
one moth.
Its known to us that there are lots of fields need to crush and grind
materials such as mining, metallurgy, construction and so on. All the materials
should be grinded and crushed from big one into fineness according to customers
requirements.
As we all know that crushing cost too much both energy and money. Since then
how to improve efficiency of crushing is one biggest problems.
Crushers are mainly used in many fields such as construction, mining and so
on. However most of such kinds of equipments have various of disadvantages such
as maintenance, capacity and so on.
Shallow talk on the bugs which affect the crushing process
Crushing process are related to many factors. In summary, there are three
main factors: mills structures of, ore attributes, and operation conditions.
However, at a production site, equipments are fixed, which should be regarded as
a fixed factor, while ore attributes and operation conditions should be
considered as key factors on the quality and quantity of products. In order to
guarantee the quality of products mills produce, operators must adjust feeding
amount and choose a most appropriate operation condition according to the ores
changing nature (granularity, hardness etc.)
Hammer crusher is
a mainly machine in mining machinery industry, widely used in cement, chemical
industry, electric power, metallurgy industry, etc. Often used in crushing
limestone, slag, coke, coal and other materials. Hammer crusher has the
following features compared with other crushers:
1). The work hammer was more wear-resisting and impact resistance;
2). Can adjusting the need size according to customer requirements;
3). The structural of hammer crusher was seal;
4). The structure is compact, has less easy to wear parts and convenient
maintenance.
Because of these advantages, the hammer crusher was very popular in mining
machinery industry. Now Now we look at how to choose a suitable hammer crusher.
1). You should choose a trustworthy mining machinery manufacturer. So would have
quality assurance, exempt from your worries about the machine. The best way is
to visit the mining machinery manufacturer by yourself, see if there is a
legitimate manufacturers.
2). Choose the appropriate size of the hammer crusher according to the
materials you want to broken. Fit is more important than anything.
3). You must determine all matters in the contract, including materials,
components and delivery time, etc.
HXJQ is a famous hammer crusher manufacturer in China which is titled as
'China Famous Machinery Brand'. Hammer crusher is one of our main products and
sold at home and abroad. Our products have high quality and reasonable price.
Favored by domestic and foreign customers, if you have any need, please for free
to contact us.
The frame is made of tetra-wall rigid steel plates opening up and down. The
frame is used to support the eccentric shaft and withstand the crushing force.
It is required to have enough strength and stiffness. Generally, it is casted
integrally by cast steel. For small machine, the cast steel can be replaced by
high-quality cast iron. For large machine, the frame should be casted section by
section and then connect the section together by bolts tightly. The casting
technique is complex. Small home-made jaw crusher can also be made by
welding thick steel plate, but the rigidity is poor.
2). Jaw plate and side plate
Both fixed jaw and movable jaw are composed by jaw-body and jaw plates. The
jaw plates are the working part which is mounted to jaw-body with bolts and
wedge. The jaw body hung on the shaft is the front wall of the machine frame.
Mostly it is made of cast steel or cast iron because it required to be strong
and rigid enough to withstand the crushing force.
3). Driving eccentric shaft
Driving eccentric shaft is the main shaft of crusher. It is made of high
carbon steel and has a huge torque force. Eccentric part requires fashioning,
heat treatment and the liner of bearing to be casted with babbitt metal. One end
of the eccentric shaft is mounted with pulley and the other end is mounted with
flywheel.
4). Adjusting device
There are generally wedge block type, pad plate type and hydraulic type etc.
adjusting devices, normally wedge block type is adopted which are composed of
front wedge and back wedge two wedges, front wedge block can move forward and
backward and block against rear push plate. Rear wedge plate is adjusting wedge
which can move up and down. The slant sides meet together and adjust outlet
opening size by screw moving up and down. The adjusting of small size jaw
crusher outlet opening size is realized by increasing or decreasing the washers
between push plate bracket and machine frame.
5). Flywheel jaw crusher
Flywheel is for storing energy not consumed during empty travel cycle of
movable jaw plate, and the saved energy will be used in another travel cycle
which makes the work load of machine become even. Pulley also plays flywheel
role. Flywheel is always made of cast iron or cast steel, small size flywheel is
normally as an integral type as fabricated. Please note flywheel static balance
during its fabrication and installation.
6). Lubrication device eccentric shaft bearing
Normally concentrated circulation lubrication is applied; the feeding of oil
to the supporting face of mandrel and push plate is normally by manually
operated oil gun which feeds lubrication grease. The swinging angle of movable
jaw plate is very narrow which makes difficulties in lubricating between mandrel
and bush. So normally open some oil groove in axial direction at bottom of bush,
and open a circumferential oil groove in the middle to make the lubrication way
through. Then forcefully inject dry grease in with oil pump to make
lubrication.
Sand maker is calling for environmental protection
Natural sand more and more lacks along with the time development, so
machine-made sand became especially important. Now we see how to eco-friendly in
machine-made sand production process.
Machine-made sand is processing through sand making machine and
other ancillary equipment, the finished product are more rules and can meet the
daily needs. At present, machine-made sand is widely used in buildings, roads,
Bridges, chemicals industry,etc. But some we all know that machine-made stone
pollution and damage the environment. So Henan Hongxing Mining Machinery develop
a new type sand making machine friendly to environment.

'The economical society', 'green society', 'a low carbon economy' hot words
such as on the network once popular, according to reports, the mining area of
tangshan nearly 1500 square kilometers, form the mining subsidence area and
affected area 280 square kilometers, including coalmine subsided water area 75
square kilometers; Iron ore and gold mining cause mined-out area and spread the
area more than 100 square kilometers. For exploitation of mineral resources to
our city ecological environment caused by the pressure, for several years,
tangshan accumulative total investment capital is 1.52 billion yuan, cause
economic disaster. Mining waste more fly ash, coal gangue and so on, is how to
deal with the rubbish be a big problem.
At present, the domestic processing mining waste technology improvement, fly
ash, coal gangue circulation and sustainable development is a kind of way. A
industry will smash production line is used for coal gangue, recovery of fly
ash, used for road, fill in the well, the sand and cement, bricks, achieved
effect is notable. Mobile crushing stand for mining waste handling, the waste
handling to a new high.
For example: Henan Hongxing Mining Machinery Co., LTD launched the mobile
crushing plant with small volume, flexible operation, convenient operation, and
to reduce the working time, go directly to the working area, including matching
jaw crusher, impact crusher, mobile jaw crusher, vibrating screen, vibrating feeder, belt conveyor, also according to
the customer's need to tailor. Mobile crushing station is widely
used in mining, coal mine, mining waste, debris and building the recycling of
waste, earthwork project, the city infrastructure, road or the work in building
site. The motor performance is good, can with the raw material or the
construction site, and can be extended with multilateral cooperation, meet
different product demand. This mobile crushing and screening into sets of
equipments including primary broken stand and secondary crushing and screening
races, and other components of the belt conveyor, stand at all levels are broken
is an independent work unit, to complete their respective for different duties,
belt conveyor is responsible for all the material transfer between crushing
station stacking machine.
'First damage, after management' is an error of ecological restoration. The
mobile crushing stood in the mine development at the same time can deal with
mining waste maintenance mine environment,improve the ecological environment of
mining area not only, also can be used for local people to bring the benefits of
the economy. In the development of green mining, out of a 'in development
protection in protection, development' of ecological, on the path of sustainable
development, mobile crushing the attack stand indelible.
Vibrating screen, according
to its movement locus, is generally classified into two kinds: linear vibrating
screen and circular vibrating screen.The movement locus of the circular
vibrating screen is a circle. The circular vibrating screen is a kind of new
vibrating screen with a large number layer and with high efficiency. It is
dedicated to the quarries screening material stone design, and can also be used
for mining, mineral processing, coal, building materials, power and chemical
industries for the classification
In order to detailed description the application of vibrating screen in the
actual operation, especially take the application of the vibrating screen in the
production of silicon carbide powder technology application for example.
The function of vibrating screen in this process:
1) Screening effect: screening is divide the granular, powder into different
sizes of the particles. A single vibrating screen can be matched to 4 layers of
screens, continuous separation of 2-5 grade of the particles and control the
narrow particle size range;
2) The effect of screening out impurities: high performance machine can
quickly remove the percent content of low large particles or separating the
small particle slurry residue in high flow process. Vibration screen can make
all kinds of slurry in the insoluble solids rapidly cleared and continuous
slagging.
The procedure of the production of silicon carbide powder:
1) The silicon carbide materials will be crushed by a crusher at first and
screened, the silicon carbide particles after being screening will be shaped by
shaping machine, and then carries on the pickling impurity removal, drying;
2) The dried silicon carbide particles will be ground into silicon carbide
powder of certain degree with a grinding mill;
3) And then use the vortex type air classifier to classify
the silicon carbide powder;
4) To have a further classify of the semi-finished products of the vortex
type air classifier cyclone export by turbine air classifier.
In recent years, many manufacturers want to substantially increase the
quantity, reduce coal consumption through the transformation of rotary dryer. But the
reforming effect of some manufacturers is not ideal, or even emerging the
situation of the cylinder liner wear quickly, the under barrel and the head of
the rotary dryer easy to burn out and the bag type dust collector using a
shorter life, and the repairing cost is high and seriously affecting the normal
production of the dryer.
It is not the reason of technical reformation problem, the effect of some
technical transformation is very good, such as the installation of X shape
lifting plate. Now many equipment manufacturers have adopted this technique, the
main reason of effecting the effect is that the main emphasis on the dryer is
transformed locality instead of modifying the dryer from the whole drying
supporting system. The announcements in modifying the rotary dryer are as
follows:
1. The selection of entilation dust removal equipment:
The ventilation effect of the dryer directly influences the yield level of
production. If you want to have a high yield, you must select the dust collector
of larger dealing capacity. Ensure the drying machine feeding end of certain
negative pressure, timely absorb the high temperature gas generated by
combustion furnace to to dryer and timely promote the heat exchange, as far as
possible to reduce the concentration of the waste and achieve rapid drying
purpose.
2. The inner transformation of the dryer:
The reconstruction investment of the rotary dryer is small and the
transformation is relatively simple, but before the modifying you must
understand the structure of the dryer, you can make a viable transforming
measure according to the daily experience. General transformation steps:
(1) Install a center X type material-raising plates to reduce heat empty
hole, prolong the remaining time of materials, improve the heat exchange
efficiency and reduce the loss of high temperature gas.
(2) Remove the feed end of spiral conveyor leaf and replace by the triangular
plate.
(3) Transform the feeding tube angle.
(4) Modify the L shaped tail lifting plate in the low temperature drying
area.
3. Attention the balance between wind, fire, material:
The main base of gaining high quality and high yield is to achieve the '
wind, fire, material balance'. Firstly determine the dust ventilation, drying
machine specifications, models and the effect of reconstruction, the combustion
furnace heating size matching. Secondly we should strengthen the operation.
The steps of disjointing a jaw crusher of Henan Hongxing
As we all know, jaw
crusher is one of the earliest crushing equipment, it has the advantages of
simple structure, reliable operation, the maintenance of jaw crusher is
relatively easy. However, if we hasn't an ounce of common sense, even if the
problems are very easy is will be difficult for us to solve. In the process of
using a jaw crusher, various problems will probably appear. In order to solve
those problems as soon as possible and minimize the losses when these problems
arise, we need master some mechanical common sense of the repair maintenance of
jaw crusher. Therefore, mastering the common sense is very important. Now we are
going to introduce in detail of how to correctly disassemble it in repairing of
a jaw crusher:
The the most frequent repair progress of jaw crusher is the replacement of
the thrust plate. As with the integral connecting rod of jaw crusher, we have to
disassemble the thrust plate at first. When disassemble the thrust plate, a
baffle plate bolt must be screwed, cut dry lubricating oil pipe, hang the thrust
plate on the crane hook or other lifting equipment, then loosen the spring of
one end of the level connecting rod, fix the dynamic jaw to the direction of
static jaw, take out the thrust plate. If you want to remove the back thrust
plate, you should open the connecting rod and the thrust plate and the static
jaw together, take out the back trust plate.
After disassembling the thrust plate, cut off the thin lubricating oil pipe
and the cooling water pipe and supported by the holder behind the connecting rod
and remove connecting rod cap, the connecting rod can be hanging out. The shaft
and pulley and a flywheel of the crusher should take out together. Move the
motor (with belt ) along the sliding rail as close as possible to the crusher,
take off the triangle belt, and then lift the shaft by a crane. When disassemble
the dynamic jaw, you must cut off the dry oil and lubricating oil pipe, then
remove the bar and remove the bearing cover and then use a crane or other
lifting equipment pull the dynamic jaw out.
Hongxing's high-frequency vibrating screen for high productivity
Vibrating screen has the
advantages of reliable structure, strong exciting force, high screen effecient,
small vibrating noise, simple maintenance, safe operation and so on. but we
should how to maintain it in the work.
First, when the equipment works normally, we often should observe pulp
density of the sieve, to make concentration be control at about 40%, so as to
improve classification efficiency.
Second, because of high classification efficiency of this screen, good
dehydrated performance, high concentration of the quantity the screen, make Pulp
liquidity of the quantity on the screen be poor, we should match water pipes. In
case of short circuit, electromagnetic vibration sensor and control box should
take strict precautions against watering. Using plastic board cover on the
vibrator, we can prevent water and the pulp being into, avoiding a short circuit
and clogging the air gap; we should always check whether each part of bolt is
loose, and whether it is tangent between screened box and chute, etc.Then, we
observe that whether ammeter pointer is more than the amount value at all times,
when sieve machine runs about a half month, we shoud adjust current nearly
forehead value (general 8 to 9 A) vibration 4 to 5 min, so that we can vibrate
the screen piece on the back things; And according to ore properties and
operational requirements, we can adjust the exciting current (amplitude), in
order to make a sieve in the highest efficiency of the working conditions, we
can work exciting current condition test.
Finally, when the screen piece is used after a month, we will take off the
screen piece, turn 180 around to enhance screening 'cutting' role, so as to
improve classification efficiency; When the pulp which a cloth give the screen
piece shoots too far, we should adjust position or angle of sieve box to avoid
affecting the classification efficiency.

Serious challenges accompanying with good opportunities in mining machinery industry
In recent years,although our country has fixed assets in control of
investment,the heat did not affect the development of the mining machine
industry,this year mining machine industry still keeps the increase of
investment.From mine machine industry in 2000 ~ 2009 of fixed assets steady
growth which can explain mining machinery industry return on capital is higher
than the average return on assets,which is worth the investment of social
capital. From our country mining machinery industry market situation,the China
foreign investment have increased. In the face of foreign capital offensive is
so strong ,at the same time domestic enterprises are facing serious
challenges.
When the country makes construction project,mining machinery industry will
have a lot of application,mining machinery in mine development,highway
construction,chemical raw materials powder processing, the dressing,building
materials raw material processing,metallurgy equipment and so on .the industry's
operations are also cannot leave the mining machinery of ball mill,crusher, and other
equipment, strong capital into that countries and investment in fixed
assets,which will drive the developement of the mine machine industry. First
look: at an early age, the federal republic of Germany abroad and the former
Soviet union have developed a hydraulic drive of the jaw crusher. Its characteristic is
to improve the dynamic jaw so as to increase the output swinging number, and can
realize hydraulic adjustment mouth, discharging hydraulic overload protection
and can load startup. The federal Germany made impact type mandibles crusher,
and the former Soviet union also creates vibrations jaw crusher.They are on
dynamic jaw vibration impact crushing material,so as to improve the crusher
performance. Henan Hongxing mining equipment rely on strong production team
production industrial rotary dryer,sand making
machine,roll crusher,impact
crusher,the mobile crushing processing equipment stations,which won the
world within the scope of the broad consumer trust. The former have developed in
our country, and for some reason not to continue development. Democratic Germany
had produced a Jane put double cavity jaw crusher, the production of double
pendulum jaw crusher cavity.
In the next step, stressed the need to improve the important technical
equipment localization, the country will mainly in the level of efficient and
cleaner power generation and transmission, large petroleum chemical industry,
mining machinery and equipment, transportation equipment, advanced and
applicable high-grade numerical control machine, automatic control, integrated
circuit equipment and advanced power device etc strengthening policy support. It
can be concluded that, along with the future construction machinery industry
layout, the industry will gradually open competition to further, the market
sales will further to large enterprises, showing a strong focus on the strong
and the weak weaker trend, domestic enterprises will need to rely on their own
power and multinational company over.
Friendship and love are similar but different. It's a problem
All of a sudden understand that friendship and love are the same. Need to be
able to pay each other to harvest, even if the party no matter how hard, the
other party has not responded to, that is of no avail. You put a person as a
friend, but the other did not mean you as a friend, even if you no matter how
sincere, your friendship will not be long; like love, like, no matter how you
like a person, that person just do not like you, In the end, you will not come
together. They all need each other in order to better co-operation.
I have been very much believe in love, though did not encounter their
husband's profile, still believe in love, I believe my love will patronize me.
Friendship is also, I have a friendship. When I am not happy, the first think of
them, because of their support and comfort, not happy to do the agenda for what.
Even if they are not saying anything, as long as it quietly let you Baoyi Bao,
by relying on their shoulders, look, your heart like calm.
In our previous post on rose history we learned roses in the United States
were being grown mostly for their ability to produce long stem cut flowers.
Quite often to the determent of garden characteristics such as attractiveness of
shrub, disease resistance and even hardiness. But this was not always the case
in other countries.
Many European rose breeding firms continued to keep their Garden Rose and
Exhibition/Cut Flower lines very separate. They bred roses for the cut flower
industry in addition to a totally separate line of Garden Roses. The German firm
of Kordes and Sohne is a prime example as is the French firm of Delbard. And
some like Peter Beales Roses in the UK simply bred only Garden Roses. But these
Garden Roses were mostly confined to Europe where the line between them and Cut
Flower/Exhibition Varieties was kept fairly distinct. In addition Europe and
most of the rest of the world has always had an aversion to chemicals for the
home market.
In the latter part of the 20th century as the U.S. became more
environmentally aware, many chemicals were thankfully being taken off the
market. While some fine Hybrid Teas were able to thrive without them many that
could only be grown with now disappearing chemicals began to flounder. Since
those roses had been marketed and sold at the expense of the true Garden Roses
it meant many a home gardener was suddenly faced with a plant that was difficult
to grow, wouldnt flourish and in many instances died off within a few years.
Sound familiar!
Roses began to get the reputation as being fussy, weak and needing a great
deal of care. Suddenly June Cleaver in her pearls was our grandmothers slaving
over her roses and we didnt want to have to work that hard!
That gardeners were beginning to look for easier to grow roses is evidenced
in the resurgent interest in the Old Garden Roses during this time. Old Garden
Roses had a reputation for being disease resistant and easy to grow. Something
they had earned because over time because the poor ones had disappeared and the
stronger ones survived. I would suspect in 100 years the Hybrid Tea class will
have gone through the same process and someone reading this will wonder what the
fuss is all about!
In the 1990s the David Austin Roses took flight in this country. They not
only had an old-fashioned look and could be planted amongst other plants but
they also had fragrance. In their own way the 're-introduced' the concept of
Garden Roses as flowering shrubs to the United States. They were marketed as
Garden Roses and once again the line between Garden Roses and Cut
Flower/Exhibition Roses began to once again strongly emerge in the U.S
Hongxing's cone crusher
characterized by a frame having a completely fabricated construction, an
anti-spin mechanism and an improved crusher setting indicator is disclosed. The
frame of the structure, which is composed solely of pre-formed and/or forged
members, includes a number of tubular members, a number of annular members and a
number of ribs, all of which are welded together to provide a rigid, strong
frame. The anti-spin mechanism is characterized by the use of a unidirectional
valve and a spring loaded ball valve, thereby permitting the rotation of the
mantle of the crusher in one direction while barring rotation of the mantle in
the opposite direction unless a force exceeding a pre-selected magnitude is
applied to the mantle. The crusher setting indicator, which is used to determine
the distance between the moveable mantle and the stationary concave of the
crusher includes a rod supported by the crusher, the rod abutting the cone
support bearing seat of the rock
crusher, the position of which seat is directly related to the position of
the mantle. A pinion gear is coupled to the rod and the orientation of the gear
is used to provide an indication of the distance between the mantle and
concave.
Granulators, or ring hammer mill, are composed of a shaft/hammer/disc
assembly rotating at medium speed (300-720 rpm depending on diameter) within a
breaker cage. Before your granulator was fully assembled, the folks in our
factory balanced the rotor assembly on a static balance stand. But after
extended service, the effects of wear on these things can cause problems such as
vibration, hot bearings and unusual wear.
If Hammers are allowed to wear beyond their point of normal replacement, they
can break and cause a serious vibration. Be sure to check the condition of all
wear parts regularly, especially the rotating parts.
Another condition that can cause vibration is improper feeding. The best way
to feed a granulator is to slide the material into the crusher along the breaker
plate, and to avoid dropping material directly on the rotor. When the crusher
mill is fed properly, wear will be uniform, resulting in longer hammer and disc
life. We can advise you on ways to feed your crusher properly so that parts wear
and maintenance down time are kept to a minimum.
Also take measurements of bearing temperatures. A hot-running bearing will go
out of tolerance and eventually fail; this is most often caused either by
deterioration of the grease or by using too much grease. Check your operation
manual, or give us a call for advice.
Flow of technology innovation breaking a new chapter
To improve the latest technology for our product and make the most elite
product for our users, vipeak following tightly the development of the

New generation of sand making machine pushed by Henan Hongxing
As the main materials of concrete aggregate system, artificial sand and
gravel aggregate are widely used in the high-speed railway, highway, municipal
construction, hydropower projects.So the artifical sand making machine update
constantly for the customers' requirments. Henan Hongxing Mining Machinery
company developed a kind of highly efficient sand maker ,which introduce the
new technology, promote the sand technology and infrastructure development.
From the early 1960s, traditional dry sand processing mathod had turned up in
China.But the traditional technology have several fatal disadvantage,such as the
poorly equipped,small production, dust hazard,big noise, environmental pollution
and so on.They matched the high energy consumption and high costs but didn't
solve the problem of environmental pollution. Henan Hongxing Machinery improved
the first vetical impact
crusher (PCL series sand making machine)and finished the world's advanced
level high-performance sand making equipment VSI type sand making machine,
which is comprised of rotor, spindle, crushing chamber, motor, transmission,
automatic control systems, lubrication systems, and steel and other components.
And the main wear parts,example the rotor matrix, throwing hoppers, sub-feed
pan, anvil , adopts wear and impact resistance alloy materials.All of them are
provided with the long life and easy replacement. The crush form is divided into
'rock on rock' and 'rock on iron'.According to material compressive strength,
abradability,there are four working forms: central with cascade feeding 'rock on
rock' and rock on iron'; central feeding 'rock on rock'and 'rock on iron'.
In conclusion,VSI Type sand maker is the international advanced level of the
new generation of energy-saving, efficient crusher. It is suitable for brittle
materials with Mohs hardness under nine, not suitable for viscous material and
rock with much dirt.
For China mining machinery industry, the 1990s is the most difficult period.
Only after 1999, it began to recover and ushered a new developmental
opportunity. However, at present its technological base is still weak. Experts
suggest that China mining machinery industry should seize opportunities to
accelerate development through research and technical innovation.
There are two major problems for China mining machinery industry. First, the
overall strength of mining machinery industry is not strong and could not meet
high-standard requirements. Second, there are a lot of problems in product
variety, technology, quality and service. Take the metallurgical and mining as
an example. Currently there are 1180 kinds of equipments used in China, but only
26 percent are self-sufficient and the remaining 74% still need to import.
To enhance this, experts propose certain approaches to increase innovation.
First, mining machinery manufacturing industry should establish different kinds
of cooperation with foreign companies and professional design institutes and
introduce technology and talents. Second, establish professional application
laboratories to research product and applied technology of manufacturing
process. Third, institutions of higher learning are not only the talent base,
but also the origin of its basic theory and experimental research.
Hot investment on high-speed railway stimulates mining machinery market
During the 12th Five Years Plan, China government will increase investment
on High-speed Railway and subway infrastructure construction. Under this
background in China, mining industry will meet with a good opportunity to make
them stronger.
1-8months in last year, the machinery industry completed a total industry
output value of 8.9 trillion Yuan, an increase of 35.31% higher than the same
period last year, and its 12 sub-sectors manufacturing showed great growth.
According to statistics, the sales of construction machinery industry in China
will reach 900 billion Yuan by 2015, the annual average growth rate of exports
accounted for 17% about 20 billion USD dollars, which is becoming the first
truly major exporter of construction and mining industry.
Henan Hongxing machinery will seize this right moment and make more
contribution to the development of our economic and people living standard.
These years, Hongxing sand making
machine-PCL series vertical shaft vertical impact crusher, PE
series jaw crusher
and excavator are commonly used at home and abroad. Hongxing staff feels it is a
great honor for them to participate in this infrastructure construction
movement, seeing most of their equipments can be used in road construction,
buildings, water and electricity construction, they are happy to provide more
good quality equipments to all the users.
The new trend in machinery industry - dedicating on Western building
In recent years, 'Go West' has made many significant achievements, a number
of key projects have been already in operation orcompleted, at the same time,
the western infrastructure, ecological environmenthas undergone tremendous
changes. 2011 is the first year of twelve fiveperiod, and the new beginning of
the western development strategy layout, whichis clearly an opportunity and a
challenge for the Chinese construction machinery enterprises.
'Twelve Five' period, particularly in the west inXinjiang, Tibet and other
remote areas will be doomed to the next battlefield forconstruction machinery
industry, a large number of key projects in westernregions started intensive,
and the western intensification of industrializationand urbanization, along with
a variety of needs increase, it will surely attract the attention of domestic
and foreign construction machineryenterprises. In addition, rich energy in
western region is being untapped. Focuson on the Western construction will be
the new trend for construction machineryindustry. Recently several major
construction machinery industry giants, such as Xugong, 31, Liugong Group, have
forward west, and make their contribution tothe western development.
As the famous mining machinery brand of China, Hongxing will supply the
advanced mining plants for the western construction. Now HXJQ has sold out their
stationary typecrushing plats and mobile crushing station
to over 100 countries and make the significant dedication for the local
construction. All the plants get ISO 9001:2000 and CE certificate.

Illustrations for ultra-high pressure crusher control
This work studied the current progress in ultra micro-crushing, and proposed
a new model of ultra-high pressure crusher. This new model will fulfill the need
for ultra high pressure crusher technology, realize the auto control of
ultra-high pressure crusher and developed the supervisory control software.
First, we made some modification to over come some defects of conventional
ultra-high pressure crusher. We designed a new type ultra-high pressure crusher
with oil hydraulic pressure. It employs by turns work of two pistons to add
pressure to material and reduce pressure fluctuant. The local control system was
developed based the designed ultra-high pressure crusher. It employs PLC as
central control, collect system information by transducer and keep the stability
of system pressure by adjusting the sequence of the pistons. This helps to
realize the automatc control of ultra-high pressure crusher. This machine can be
operated both manually when adjusting the equipment and automatically during
routine work.
Supervisory control software was compiled with vc, thus realize the remote
monitoring of the machine. With the system real-time pressure value collected by
a pressure sensor, this system collects signals to supervisory control computer,
in whicb the pressure is described with dynamic curves and the real-time
information of pressure is stored into access database. The ultra-high pressure
crusher with PLC and supervisory controlling is able to work stable under the
working pressure as high as 200MPa.
For excellent screen result, to choose proper mesh shape
The mesh shape directly influences the effective area of the screen. The
effective area, also called effective screen surface, refers to the ratio
between the sieve mesh area and the geometric area of the screen surface. The
larger the screen effective area is, the more screen meshes there will be on the
unit screen surface, and meanwhile the bigger probability of materials passing
through the screen mesh there will be. Thus, the production capacity and the
screening efficiency will be higher.
In the screening operations, the commonly used mesh shapes include round,
square and rectangle. The sieve mesh of the perforated screen surface is round,
while the woven screen surface is with rectangular hole and square hole.
Practice has proved that screen surface with different mesh shapes has different
effective screen surface areas, and at the same time the probability of mineral
grains passing through the screen mesh is different as well. In general, the
rectangular screen mesh has the biggest effective area followed successively by
square mesh and round mesh. Therefore, the productive capacity of unit screen
surface area becomes smaller according to the above order. One of the
rectangular meshs advantages is that the sieve mesh is difficult for
clogging.
Finally, the mesh shapes should match the shapes of the materials. Generally
speaking, the lump materials should adopt the square hole, while the plate
materials should select the rectangular hole. The mesh size and grain size are
determined according to the following formula: dmax=ka.
Let's know about the mobile crushing plant together
Exactly speaking, the mobile crusher should
be referred to as mobile crushing plant, as it is equipped with discharge device
and some other ancillary facilities besides crushers. According to different
mobile functions, the mobile crushing plant can be classified into fully-mobile
type, semi-mobile type and portable type. The three types of mobile crushing
plant have different working conditions.
The fully-mobile crushing plant can also be called self-propelled crushing
plant. In accordance with different moving modes, it can be divided into crawler
type, rubber-tyred type and walking type. The flexibility degrees are different
for the three types of moving modes. Thus, they have different uses. Generally
speaking, the crawler type mobile crushing plant can work in coordination with
excavators. However, it is restricted by the heavy machine body, so it has a
relatively small processing capacity. Currently, its largest known capacity is
1000t/h. The rubber-tyred type and the walking type can only work under
relatively fixed conditions. Unlike the crawler type mobile crushing plant, they
can not work in coordination with excavators. However, they have large
processing capacity, which can reach up to 2000-3000t/h.
The semi-mobile crushing plant can move by means of some external forces.
Material feeding and discharging can be completed on the same platform for some
semi-mobile
crushers, while some can not. At present, the largest semi-mobile crushing
plant in the world is found in a copper ore of Chile, whose processing capacity
has reached up to 9600t/h. Basically speaking, the semi-mobile crushing plant is
elevated on the ground dispensing with solid concrete foundation. Therefore, it
can be uses as long as the carrying capacity to the ground is not less than
250KPa.
The portable crusher plant,
also known as modular crushing plant, is a kind of structure between the fixed
crushing plant and mobile crushing plant. It can be disassembled into several
parts. Its size and weight are in line with the cranes lifting capacity and the
trailers bearing capacity. The time it takes to relocate the portable crushing
plant depends on the preparation, disassembling degree, and relocation distance,
etc.
The selection of crushers for cement plant should take into consideration the following factors raw materialsâ hardness (generally represented by the compressive strength), corrosivity (usually described with free quartz content), and viscosity (water con
The selection of crushers for cement plant should take into
consideration the following factors raw materials hardness (generally
represented by the compressive strength), corrosivity (usually described with
free quartz content), and viscosity (water content, and clay content). In
accordance with the above information, you can make a choice.
The requirements on limestone crushing are relatively high. After being
processed, the particle sizes can reach 0~25/80mm. The crushing processes should
be reduced to the greatest extent, so that the one-time investment and
maintenance costs can be reduces. The hammer crusher or impact crusher with high
crushing ratio can meet the requirements for single stage crushing, but the
quartz content should be less than 8%-12%. In terms of the impact crusher, the
water content of the materials should be less than 8%. On the part of the
biaxial hammer crusher, the water content can reach up to 20%, and limestone and
clay can be fed at the same time.
If the quartz content and water content are so high that hammer crusher or
impact crusher cannot be used, two-phase crushing system should be adopted. In
general, the double roller crusher, roll sizer, jaw crusher as well as cone
crusher are suitable for the two-phase crushing system for abrasive materials.
Their crushing ratios are much the same (about 15-16), but their adaptive
capacity to hard or wet materials is quite different. The jaw crusher and cone
crusher crush the materials by means of high pressure, and they can handle hard
rocks with compressive strength up to 400Mpa. The double roller crusher and roll
sizer are influenced by shear and pull force, and they are only suitable for
crushing materials with compressive strength less than 175MPa. However, they can
process materials with high viscosity and corrosiveness.
HX's crushers just like natural enemy of Granite stone
Graniteis a common and widely used type of intrusive, felsic, igneous rock.
Granites usually have a medium- to coarse-grained texture. Occasionally some
individual crystals are larger than the ground mass, in which case the texture
is known asporphyritic. A granitic rock with a porphyritic texture is sometimes
known as porphyry.Granites can be pink to gray in color, depending on their
chemistry and mineralogy. By definition, granite is an igneous rock with at
least 20% quartzby volume. Granite differs from granodiorite in that at least
35% of the feldspar in granite is alkali feldspar as opposed to plagioclase; it
is thealkali feldspar that gives much granite a distinctive pink color.
Out crops of granite tend to form tors and rounded massifs. Granites
sometimes occur incircular depressions surrounded by a range of hills, formed by
the metamorphic aureole or hornfels. Granite is usually found in the continental
plates of the Earths crust.
Henan Hongxing Mining Machinery provides granite crushing machine, and our
product plays an important role in the mining of granite. Granites usually have
a medium- tocoarse-grained texture. Its compressive strength usually lies above
200 MPa. We usually take Jaw
Crusher and Impact Crusher
as the primary crusher because ituses the stone strike stone technology can
raise the effect and save the powder. Cone Crusher is the best choice as
the second crusher.
Aggregate processing includes crushing, screening, and cleansing the
aggregate to acquire proper cleanliness and size. If necessary, benefaction
process for example jigging or heavy media separation can be used to upgrade the
standard.
In mining industry, crusher is usually used for crushing raw materials, with
more than 8 mm thick. Crusher can be divided into primary crusher and fine
crusher. Generally speaking, the processed materials can be 0.074 mm thick, or
even smaller. The process is use outside force to crusher bigger materials into
smaller.
In cement production, most of the materials need to crusher. Limestone takes
a large proportion in cement processing, and has high hardness and large
particles, so it also need to be processed by crusher. Jaw crusher, impact crusher, shaft
impact crusher, and hammer
crusher, they all widely used in cement plant.
As fast development of the society, the mounts of crushing material is
increasing heavily, crusher plays more and more important role in our national
economy.
Henan Hongxing Mining Machinery Co., Ltd has designed and manufactured a
large amount of various crushers, a series of new rock-crushing equipment, which
largely expands the concept domain of coarse crushing and fine crushing, such as
PE/PEX jaw crusher, vertical impact crusher, hydraulic cone crusher, mobile crushing station. It has
successfully removed the obstacle that crushing site, environment and complex
infrastructure. HXJQ has made great contribution in cement industry, and we will
always on the way!
As fast development of the society, the mounts of crushing material is
increasing heavily, crusher plays more and more important role in our national
economy.
Status and suggestions on China construction waste disposal
Nowadays, the increasing rate in China has already been more than 10% while
the increasing speed of the construction waste all over the world is 8.42% every
year. The global construction waste is about 490 million ton; whereas China is
about 150 million ton. The municipal solid waste in China has piled about 7
billion ton. Such great pressure from the construction waste, we believe that
waste disposal will become the major industry in the future. Especially the
recycling of construction waste, because it can bring more economic benefits, so
it is inevitable to become the important part in the waste disposal
industry.
Construction waste disposal is the process of planning and implementing the
handling and disposal of building materials on a construction site. Research,
training, and development of a construction waste disposal plan are integral
parts of this process. It involves applying the conservation hierarchy: reduce,
reuse, and recycle to construction materials and methods.
At present, the building demolition debris (the waste produces in the course
of constructing, renovating, and demolishing buildings) accounts reach 30%-40%
of the total municipal waste. This debris is composed of excess building
materials that contain valuable resources and embodied energy from their
production and transportation to the jobsite. Both architects and contractors
can greatly impact the amount of construction waste generated on the site. Once
materials have been consigned to the landfill, these resources are virtually
impossible to recover. Recognizing and fully utilizing building materials value
is the foundation of construction waste disposal.
Henan Hongxing Mining Machiney Co., Ltd. develops many new generations of
machines, movable crushing plant, energy saving cone ball mill, high
efficiency micro-powder grinder, ultra-fine Raymond mill relying on
the features of construction waste. This equipment solves effectively the
problem about the recycling of construction waste. Thus it brings the more
economic benefits and realizes the maximum of resource utilization.
The grasses rooting in the expansion of drying equipment
After 20 years' development, the drying equipment industry in China has
formed a certain number of enterprises and production scale. From the regional
distribution of the manufacturers, the number of the east part is more than that
of the middle and western part; especially in the Jiangsu, Zhejiang, Shanghai
the enterprise is relatively concentrated, only in Changzhou City of Jiangsu
Province, the number of the drying equipment production enterprise has been more
than 50. The current conventional drying equipment in the domestic market as
well as the main drying equipment in the international market, we basically can
have its own manufacturing in our country, which suggests that, the importing
history of the drying equipment of China has come to an end. But there are still
some problems and secret worry.
The concentrating distribution of the enterprise
The producing enterprise of drying equipment industry in China mostly
gradually derive from the early enterprises of the industry, the geographical
location is relatively centered and the personnel structure exists serious
defect. So far, the enterprise is mainly distributed in the Jiangsu, Zhejiang,
Shanghai, Liaoning, Heilongjiang, the enterprise of this several area businesses
is accounted for almost 50% of the total number of entire industry, what forms
the sharp contrast with which is that there are still areas without drying
equipment production enterprises. The industry competition is fierce, some
enterprises focus on the immediate interests, which severely hamper the normal
development of the industry.
Technology development capability not strong
Since the reform and opening up, especially in recent years, China's economic
growth potential have been effectively release, the relationship between supply
and demand by the shortage economy produces a fundamental change, buyer's market
preliminary formed. In the pressure of buyer's market, some enterprises are
after market rather than to seek and explore the market, and the enterprises
focus on the products in more market demand or the developed recently. Therefore
manufacturers are more concentrated in oven, vibration fluidized bed, spray
dryer and other common products and the competition is unusually intense. We
should to research and develop new products to change the status quo.
In recent years, with excess capacity and homogeneity intensifies in China's
crusher industry, which increased competition in the market .Some companies
began to adopt some irrational promotions from buy product draw large domestic
appliances to get prizes such as cars, small breakers until the introduction of
mortgage purchase zero first-pay promotional measures.
Irrational promotions for these phenomena, it is clear that is incorrect. It
is unfortunate, crushing machine industry has now caught in a vicious circle:
obviously people cry 'zero down payment', but a lot of enterprises on the use of
such means. First of all, there are only some small enterprises to participate
in, and later even the large well-known companies are involved, promotional
products from certain categories of aircraft gradually spreading to more
machines. Or even exclude some enterprises while shouting slogans against unfair
competition, but side with others to follow use such means.
In fact, this phenomenon is not hard to understand in the vital interests of
the real face of market share. Few companies are able to self-discipline truly.
In fact, we all know that trade associations are not much binding to
enterprises. Moreover, our law does not require enterprises which are not
allowed to implement a zero down payment . In a market economy , naturally has
its set of rules of the game .
Now , China crusher(jaw crusher) market
opportunities have emerged , 'tiger ' will come here. Tiger said here ,including
the macroeconomic slowdown , tightening of monetary policy , tough credit
environment, including market advances , the adverse situation of excess
capacity ,rising raw material prices increasingly, labor costs ,as well as
emerging problem of adverse market order. Due to these 'tiger' catch-up,in the
crusher industry more than a hundred Chinese Original Equipment Manufacturers
and component manufacturers have started a super- scale long-distance race. It
is the the competition between enterprises has become not only the competition
between product quality, But also the competition for technology, markets,
capital technology , services ,marketing channels, R & D capabilities , and
many other elements.
We want to ensure that our customers' crusher equipment safe and efficient
production . At the same time ,the way to humane high- service brings a large
number of customer loyalty , actively strengthen of determination China crusher
.
