It's a rigorous work to run the sand production line
Because it is a series of equipments instead of one sand making machine from starting
the sand production line to its normal operation, the operation is a very
rigorous work, so there must be a professional personnel to start it. Owning to
the multi-equipment, hard work, high degree of difficulty, which requires the
staff very well master the run and operation steps. We will introduce few
operation specification and matters need attention in the operation, and the
details are as follows:
Matters need attention when starting a sand making production line : after
preparation, according to the provisions of the driving sequence operation to
start the main motor, when starting the motor we shoul pay attention to the
current meter of the control cabinet, after starting the peak current for
30-40s, the current will reduce to a normal operating current value. In the
normal operation, we also should pay attention to current which should not be
more than the specified value. After the normal operation of the jaw crusher, it can actuate the
feeding machine, and according to the block size and the operating condition of
the jaw crusher adjust the feeding machine belt and change the feed quantity.
Usually, the material stacking height in the crushing cavity should not more
than the 2 / 3 of crushing chamber, and the diameter of the materials should not
be more than the 50%-60% of the inlet width, the jaw crusher has a highest
production capacity at this condition. When the materials with larger piece, it
will cause blockage affecting the normal production. To prevent metal ( such as
the spade teeth, crawler plate, bits ) from entering the jaw crusher and avoid
damaging the machine, it should be brought out when they pass through the jaw
crusher to prevent causing accident; when the electrical equipment automatic
trip, if the cause is unknown, forbid forced continuous starting.
Clearing the operation specification of various equipments in sand making
production line is very necessary for the safe to human body and equipment
application.
In efficient coal exploiting, crushers as well as grinding mills
The exploration and utilization of coal has played an important role in
economy development, but causes great damage on environment. Coal gangue and CBM
development are the main wastes. The coal gangue is the solid waste produced
during the excavation, mining and washing process of coal. It consists of
carbon, shale and sandy shale, and has a low calorific value. The carbon content
is 20% ~ 30%, some contain humic acid. They exist in large quantity in countries
of rich coal resources, which not only piles up the place and contaminate the
environment but also causes fire due to auto-ignition. As energy is increasingly
short, people gradually realize these wastes are employable. If the coal gangue
can be differentiated and crushed by breakage and grinding equipment, such as jaw crusher, impact crusher,
grinding machine, they can be utilized to achieve economic benefit in roughly
five aspects:
1). Filling the colliery. The coal gangue can be used as filling materials in
underground coal cavity directly or after processing.
2). Filling the ground such as road building.
3). Generating power. Coal gangue containing rich carbon and high calorific
value is used for fluidized bed and circulating fluidized-bed power
generation.
4). Building materials. The coal gangue is made into gangue brick, cement and
lightweight aggregate to act as building materials.
5). Extracted sulfur ore or other chemical products from coal gangue and
other
All these utilizations need crushing by jaw crusher, impact crusher, Raymond milling
machine, High pressure suspension grinding mill, micro-powder mill.
The further steps on the stage of small crusher markets
With the development of construction industry, machinery industry expands
fast, such as crusher market. The varieties of crushers are many, jaw crusher, impact crusher, small jaw crusher,
cone crusher, hammer crusher, roll crusher, mobile crushing station
... Here, we talk about the future of small crusher market.
Along with our country the acceleration of highway construction, small
crusher industry in recent years to get its rapid development, the market has
the rise. According to information, at the present time, the both product can
normally use, and small broken equipment utilization is increasing. Pavement
construction industries make small crusher products circulation quickly, the
market situation were promising.
As is known to all, China is a big country, but according to the mineral
resources in China, the characteristics of mineral resources in exploitation, we
must be careful to the dressing, so, the mineral processing machinery industry
in China to bring the very big development space. From last year at the in
Tianjin China mining and this year in Nanning china-ASEAN mining cooperation at
the BBS that countries continue to intensify for mineral exploration, and
increasing the development of mining investment policy to encourage Chinese
companies to go out of the country and the world mining resources development
cooperation.
As a conclusion, the demand of crushers will continue to increase, but at the
present China mining machinery enterprise with foreign trade enterprise overall
difference is bigger, the products less competitive. So crusher product price
and the same products abroad also have a large gap, increased research efforts,
improve product quality is still domestic crusher enterprise most need the
problems faced.
For saving energy, using Energy saving cone ball mill of Hongxing

The ways to enhance the effect of coarse flotation and increase flotation capacity
As we know, there are two main types of ore beneficiation process:
flotation process (Flotation machine) and
magnetic process (Magnetic saparator). In each type, there are also coarse
beneficiation and fine beneficiation. The flotation effect for coarse grained
mineral grains is poorer in general process conditions. In order to improve the
coarse grained flotation, we can use the following special process.
1. Selection and adjustment of the flotation machine
Practice has proved that the strong turbulence movement of pulp in the
mechanical agitation flotation machine is the main factors to promote ore grain
fell from bubbles. Therefore, we should reduce turbulence intensity of pulp
movement, which can be the ultimate measure for coarse particle flotation. So we
can take measures according to the specific circumstances.
(1) We should choose the special flotation machine which is suitable for
coarse grained flotation, such as flotation machine of ring shoot type, skinnier
type flotation machine, bubble sorting and fluidized flotation machine, etc.
(2) We should improve and adjust the structure and operation of the
conventional flotation machine, we can reduced groove depth (use shallow groove
type), shorten float up journey of the mineralization bubbles to avoid mine
grain fall off, we also install flotation above the impeller area to dampen the
pulp turbulence intensity, and to maintain stable foam area, to increase air
inflation capacity, in order to form more air bubbles. So it can promote the
formation of magnetic particles float group and it makes coarse grained rise up.
When we scrap the bubble, it is quick and smooth.
2. We can properly increment pulp density and improve reagent regime.
We should choose the strong power of collector and rationally increase
inhibitors consistency, the purpose is to increase the solid strength between
mineral and the bubble, speed the risen speed, in addition to add nonpolar oil,
such as diesel, kerosene auxiliary of collector, it can 'consolidate'
surrounding which three-phase contacts, to enhance the solid strength between
mineral and bubbles.
An arduous task for ball mill manufactory â Qualified standard of Cement ball mill
The ball mill as
universal grinding equipment, is widely used in cement, mineral processing,
building materials and chemical industries, the ball mushroom machine can be
divided into two kinds of dry and wet grinding method. According to the
discharging in different ways, can be divided into the grate type ball mill
overflow type ball mill two.
Cement quality, from the grinding process, and the mill before crushing
separator efficiency has no direct relationship. China's cement quality
inspection index in general there are two: Cement sieve residual value and
specific surface area. Our Hongxing is committed to improving the quality of cement mill. But internationally on
cement inspection standards are constantly changing, which requires
manufacturers continue to improve production technology of ball mill, executive
cement new standard, cement sieve residue values of this index has little
practical meaning. New standards for specific surface area to pay more attention
to some, but the cement particle gradation, no specific requirements. Ball mill
manufacturers generally executive cement new standard, must be substantially
improve cement product quality, accelerate the elimination of backward, promote
market competition, with ball mill grinding cement standard to conform with
international as soon as possible, as China's accession to the WTO after the
cement industry into the international market for. In this way, China ball mill
plant, especially small mill plant how to improve cement quality, has become an
urgent need to solve the problem.
Our company mill expert expresses, improve the mill after the cement quality
in many ways: adjustment of raw material proportioning, sintering process,
change, strengthen the mill equipment management and so on, these are required
by the production of cement units on their own, and the ball mill manufacturers
also takes a long time to research and improvement, we can do is the ball mill
grinding process improvements, improved the quality and output of ball mill.
The domestic price of Rotary kiln for your reference
In recent years, the demand for Rotary kiln in China is
increasing, and in order to meeting the trend, the manufacturers of Rotary kiln
make technological innovation, such as medium-sized rotary kiln, rotary kiln and
ultra large scale rotary kiln and other new products.
However, the industry has a problem: the price fluctuations of rotary kiln,
rotary kiln is very difficult to stabilize prices. Our Hongxing expert group
specialized in last few years the price trend of rotary kiln to make scientific
analysis, expert thinks, domestic rotary kiln prices changing, upper and lower
fluctuating, it is because we are in rotary kiln of many manufacturers, and not
standardized, at present, our country has quite a part of rotary kiln
manufacturers are not perfect infrastructure, produced by the rotary kiln
equipment does not meet national standards, the price also rotary kiln and
unrealistic, even some small manufacturers in order to disrupt the market,
deliberately low price of rotary kiln, and after the regular manufacturers out
of the rotary kiln prices far higher than the illegal small manufacturers of
rotary kiln price.
Believe, in the future 5-10 years, our country will promulgate a series of
regulations, normative machinery industry rotary kiln price, pass
macroscopically adjusting control, so that the price of rotary kiln tends
stable.
Rotary kiln can be divided
accoding to two approaches. The first dividing method of rotary kiln is by
structure. It can be divided into horizontal rotary kiln and vertical rotary
kiln. The second method is by manufacturing type. It can be divided into wet
method rotary kiln and dry method rotary kiln. Wet type rotary kiln is mainly
used in cement wet type production. Cement wet type rotary kiln is used to
process material slurry made of raw material and water which make up around 35%.
Because slurry inside rotary kiln has mobility and all kinds of material inside
rotary kiln mixed fully and evenly, the cement clinker calcined in rotary kiln
has very good quality. All these are the advantages of wet type production by
rotary kiln. While different from wet type rotary kiln, dry method rotary kiln
has opposite benefits. Dry method rotary kiln is used to process raw material of
dry powder which has water less than 1%. Therefore, Dry method rotary kiln can
save the energy which is used to evaporate water in wet type rotary kiln.
However, the energy consumption of dry method rotary kiln is still not low
because the high temperature of waste gas. And material inside dry type rotary
kiln mixes badly and components of material inside dry type rotary kiln
distributes unevenly. So, the most popular kind rotary kiln is wet method rotary
kiln.
Ball mill is the fine
grinding machine in the industry, which is suitable for grinding various ores
and other materials, it is widely used in the ore dressing, building and
chemical industry, Because of the working strength requirements,its daily
maintenance is very important especially lubricant replacement maintenance is
especially important.
1. All of the lubrication oil shall be taken out after f the ball mill
continuously running for one month, clean thoroughly, replace new oil. And then,
change the oil every 6months.
2. Inspect every lubrication point lubrication system and the oil surface
height every other 4hours.
3. When the ball mill running, main bearing lubrication oil temperature
should be no more than 55℃.
4. When ball mill running normally, driving shaft and the gear boxs
temperature should be no more than 55℃, Highest do not exceed 60℃.
5. Girth gear and the pinion gear transmission smoothly, no unusual noises,
adjust the gap when necessary.
6. Ball mill running smoothly, no strong vibrating.
7. Motor current should be no abnormal fluctuations.
8. Each connecting fasteners should not loose, combined surface is no oil
leaking, no water leaking, no ore leaking.
9. Add the grinding balls according to the wear pattern and add the balls
timely.
10. Stop the ball mill and maintain if finding abnormal conditions.
11. Ball mill liner should replace when there is 70% attrition or have 70mm
long crack.
12. Replace the liner bolts when it loose or wear.
13. Replace the main bearing when there is serious wear.
14. Replace the grid plate of the grate ball mill when it wears.
15. Girth gear surface wear to a certain can flip sides continue to
use.
How to deal with the high intensity rocks, crusher is the powerful arm
When the crushers used for the basalt, granite, river stone, and other high
strength of hard materials, you must note that: design the reasonable crushing
technology, for the investment, you should consider the stone production line cost, and
also consider the investment cost in the local place.
There are three factors that affect stone crushing: the crushed materials
hardness and crushed stones type, the materials silica content, water content,
the materials average size, output size and the output size proportion, finished
products usage, production capacity per hour, etc. In the actual crushing line,
some materials are lime stone, the jaw plates wastage of the jaw crusher is very
low, one pair of jaw plates can use one year is very normal, because limestone
is low hardness, and the silica content is very low, so it is high wear ability
and low corrosive.
When the materials are basalt, granite, the crusher equipment production cost
is far greater than the limestone production cost, therefore, when we design the
crusher equipment, try to select the laminated principle of crusher equipment to
reduce the resistant parts consumption. Typical laminated crusher equipment is
the stage of jaw crushers, or
jaw crusher add the sysmons cone
crusher technology. If the customers have high requirements of the final
stones, we can select the impact
crusher for shaping crushing, then this will form a three stage of crushing
technology; three stage of crushing will cause the high cost, but for the long
operation of stone crushing
plant, reduce the three stage of crushing is possible, for the hard crushed
materials, can adopt the jaw crusher and the impact crusher to form two stage of
crushing technology, but this will cause the impact crushers impact hammer
quick consumption, the blow bar is shorter life, and more returning materials,
etc.
Crusher equipment industry needs to develop continually, need to meet the
customers' requirements continually. In the process of urbanization and
industrialization of highway, rail, water conservancy and other major
infrastructure investment is increasing, which will increase the large demand
for the crusher equipment. Our crusher equipment include stone crushing plant,
spring cone crusher, jaw crusher, impact crusher, high efficiency fine impact
crusher, building wastage crushing equipment, etc.
The discrepancies between Grid type ball mill and Overflow type ball mill
Grid type ball mill
finished product size can be 0.2-0.3mm,therefore can be used in the first stage
of grinding, and from closed circuit with the spiral classifier. Overflow type ball
mill finished product size is less than 0.2mm generally, therefore, suitable for
the second grinding stage for regrinding in the two stages of grinding. Grid
type ball mill is able to discharge the qualified products timely,reduce ore
over crushing, high efficiency of grinding ores,the production capacity is
higher 15% than the same specification of overflow ball mill, can load more
balls. When the materials need to be groud t 48-65 mesh, adopt the grid type
ball mill is better. The beneficiation production line can select suitable ball
mill type and model according to the actual requirements.
In Bible, the God creats the human who is the Creator. What is the real
Creator meaning? In my opinion, Creator is someone or something which meets the
demands or times. Creator or Creater is holy. OK, let's go back to the theme -
Hongxing's Ball mill.
Ball Mill is an efficient tool for grinding many ball mill materials into
fine powder. Ball Mill is used to grind many kinds of mine and other materials,
or to select the mine. It is widely used in building material, chemical
industry, etc. There are two ways of grinding ball mill: the dry way ball mill
and the wet way ball mill.It can be divided into tabular type and flowing type
according to different expelling mine. To use the Ball Mill, the ball mill
material to be ground is loaded into the Neoprene barrel that contains grinding
ball mill media. As the barrel rotates, the material is crushed between the
individual pieces of grinding ball mill media that mix and crush the product
into fine powder over a period of several hours . Quite simply, the longer the
Ball Mill runs, the finer the powder will be. Ultimate particle size depends
entirely on how hard the material you're grinding ball mill is, and the time how
long the ball mill runs. Our ball mill have been used to grind glass, powder
food products, create custom varnishes, make ceramic glaze, powder various
chemicals, and make Black Powder.Welcome your inquiry to purchase.
Have a riddle: what is the crucial equipment for grinding after crushing
Answer: Cement mill is
crucial equipment for grinding after materials are crushed. It is an efficient
tool for grinding cement mill various materials into powder.
With regard to the use of cement mill belly bulge appeared in the process,
there are cement mill several factors:to see whether the cement mill to the mine
mouth spit normally expected, if not properly spit expected, is likely to lead
to bulging belly cement mill;listen to the sound of the cement mill; if the
smaller changes the cement mill sound it is very possible to be cement mill ball
bulging belly;look at the current cement mill control cabinet, so they think
that when the current value is likely to become larger cement mill expansion
belly of the precursor is in fact not the case, if the cement mill ball bulging
belly, its current value is become small. So we need to pay more attention to
operating the cement mill correctly. Cement mill operating principle: cement
mill is horizontal type and tubular running device, has two warehouses. This
cement mill machine is grid type and its outside runs along gear. The cement
mill material enters spirally and evenly the first warehouse of the cement mill
machine along the input material hollow axis by input cement mill material
device.

Modern time is the time for Super, such as Superfine grinding machine
Superfine pulverizing technology of milling machine is a new crushing
engineering technology developing with modern technology and new materials
industry. Now it has become the most important industrial minerals and other raw
material processing technology, which has important significance to the
development of high-tech industry. We company has developed and manufactured
Untra-fine Raymond
mill, superfine micro-powder grinding machine.
Chinese powder industry has become one of the major cross-industry and
interdisciplinary industry, the output of powdery industry has accounted for
half of the total industrial of the first and second industry, which has great
impact on the national economy. Professor Hu Rongze, Chairman of Chinese Powder
Industry Association (chips), said : Due to its extensive , advanced and
practical, powder industry has an important strategic position in the whole
national economy. Superfine grinding technology is penetrating in the industry
and the high technology fields, it was known as the origin of modern high
technology. Superfine grinding technology has been widely used in chemical
industry, metallurgy, mining, building material, chemical, food, medicine,
agricultural, environmental protection and aerospace and other fields. After the
superfine crushing, the superficial area of materials increased, and this may
cause other changes, and greatly improve the use effect and utilization of
materials.
In recent years, mill equipments play a vital role in its project territory.
Nowadays, mining machinery mill industries have passed on the vulgar stage that
depend on cheap labor and the cost of the environment, in order to comply with
the international trend of low carbon economic development, mill industries are
actively explore the path toward saving energy and environmental protection.
This not only demands the government to change ideas, but also demands the vast
number of grinding machine manufacture enterprises to further emancipate their
mind, extend their vision , view industry development with international
perspective. With rapid development of mill industry, batches of elite
enterprises were emerging in China. Chinese powder technology, from production
to application and equipments manufacturing all has made great progress. New
equipment and new products on the market show strong vitality and vigor. Henan
Hongxing Mining Machine Co., Ltd. which is a enterprise major producing crusher,
grinding machines and sand making machine,

developed countries gradually opened, China may become completely power of
superfine pulverizing technology and product manufacturing. Nowadays, Chinese
mill enterprise are manufacturing high quality products with scientific
management, perfect manufacturing process, innovative concept, first-class
manufacturing test and quality control means, and there is no doubt this will
lay Chinese grinding profession leading position.
Sand maker has a
development history in China.Since the 90s of last century,there has been a
study of artificial sand. Then many provinces and cities such as Tianjin,
Shanghai, Chongqing, Guangdong, Zhejiang, Hebei and so onthat were lack of sand
resources started to study the development and application of artificial sand,
and a lot of artificial sand making production line was founded. However, as
there was no artificial sand entries in sandstone international standard, many
limits and resisitance were existed in construction using of artificial sand.
With the coming of the 21th century, the implementation of new national
sandstone standard has providied theoretical basis for the production and
application of artificial sandstone.
With the continually expanding of enterprise scale, the demanding of
technology equipment of sand makerare becoming higher and higher. As the famous
and professional manufacturer and representitive of mining machine in China,
Henan Hongxing has developed and studied a series of expert sand maker.
In one family, there isn't improtance and unimportance for everyone's role
Crushing is the low-energy phase of the comminution process, and grinding is
the high-energy phase. Crushed products for direct use are known as aggregates,
which are hard inert materials used for mixing various-sized fragments with a
cementing material to form concrete or mortar.
Aggregates are used in commercial centers, homes, airports, highways,dams,and
streets. When aggregates from natural deposits were not available, they were
made from rocks by hammer and chisel, or sometimes even in a mortar pestle, and
later in crushers developed for the purpose.
The whole secret of the efficient reduction of material lies in a suitable
crushing unit of the right capacity. This, I suppose, is obvious, but when one
looks at some of the reduction plants in operation one is inclined to the belief
that obviousness of such a statement has escaped at least a few. The best way to
reduce any material is also the cheapest:the energy must be priportioned to the
work in hand, otherwise either the work is not being done property or energy is
being wasted.
During the second half of the 19th century,investors responded with jaw and
gyratory crushers that are still used today,among them the blake jaw crusher that was patented in
1858 and the Gates gyratory crusher that was patented in 1881.
By 1850,Smooth double rolls for grinding ores driven by 15-kw motors were
operating at 50 rpm and grinding 60tpd of siliceous ores. These rolls had come a
long way from the ones that Taylor used in Cornwall in 1805. From 1890 to 1910,
the cyanide and flotation process were established, and reliable fine crusher
were required to grind ores at high rates to less than 5 mm, which was suitable
then for ball mill feed. Roll
crushers were the answer, and models were built that were stronger and more
compact than those previously available and operated at high speed. By 1925,
rolls were 1.8m in diameter and 0.53 m wide and were powered by 112-Kw
motors.They typically ground siliceous ore to -3mm.
It is needed to be noticed that an ore is usually composed of several
minerals which have different physical properties and sometimes those are
differences are big. When this type of ores is crushed, the minerals in it are
crushed differently. Some of them are crushed to thick particles while the
others are crushed to fine ones. And the phenomenon is called selective crush.
The key reason for the occurrence of selective crush is that the mechanical
property in each mineral is big and the property of crushing machine also has
influence on it. For example, Impact crusher, Jaw crusher and
autogenous mill are easy to create selective crush. And it should be noticed
that it is important in mineral separation. For example, toward those ores whose
useful minerals are easier to be mud than gangues, their granularities which
possess useful disintegrated minerals should be distinguished without waiting
for the whole ores are grinded to the same granularity for it is good for
reducing overcrushing.
After understood the mechanical property of the ores and force application
situation of crushing equipments, it should be considered that the force
application method of crusher should fit the property of the ores and then there
will be good crushing effect. Toward the hard ores, crush them by adopting
bending and impact for grinding and stripping will damage the equipment
seriously. Toward those fragile ores, bending and splitting is better. If choose
grinding and stripping, there will be too much extra-fine powder. Toward those
tough or extra-tough ores, it is reasonable to adopt grinding and stripping
crush. For the dynam property of the materials is different, the crushing
equipments for them are various.
