Are you worried about garbage disposal? Hongxing helps you
'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.
