For an enterprise success with the quality, professionalism relies the dream
With the sharp rapid development , the construction of buildings need a lot
of sand and also the sand are not the same quality requirements, artificial sand
compared with natural sand, rough appearance and shape is the main difference.
Look less rough and the shape of round, concrete pouring for the mobility when
an adverse effect, this will cause poor mobility of concrete into the gap
created, directly affecting the quality of the projects. Therefore, the
advantages and disadvantages of artificial sand quality should be the main
points of the rough in appearance and shape of the circular degree of the other,
artificial sand production of raw materials, synthetic materials, there are
other limitations must be caused by manufacturing industry and construction
companies face serious on the issue.
Although the river sand in construction has very many advantages, but the
dwindling resources of river sand, sand from the direction of the construction
industry began to search for new sand source. With the building of the
indicators require the improvement of the natural sand and natural weathering
due to the geographical distribution of different generation conditions, and
present physical and chemical indicators of volatility, which for the concrete,
especially high-performance concrete is certainly not conducive to the stability
of quality. In fact, can be resolved through artificial natural sand presence of
these shortcomings. And because the decrease river sand, artificial sand in fact
not only solved the problem of the shortage of natural sand, but also an
important raw material of high quality concrete.
Coarse sand and rounded appearance of the poor degree of main production
equipment from the mechanism determined by sand. From the perspective of
industry associations, like the springing of artificial sand production, with
the herd instinct of the phenomenon, many practitioners lack professional
knowledge, coupled with some low-quality equipment manufacturers focus on
profits, the market appeared a large number of poor and immature equipment, to
the healthy development of artificial sand brought serious consequences.
Therefore, any investment there are risks, artificial sand investment is no
exception, investors need to note, in addition to market demand and prospects,
but also need to be careful enough there in the expert consultation.First, we
must know that sand production is the cost is high, and if that is simply
crushed stone sand, in products for the technical indicators are not clear on
its easy access, investors may have to be a heavy price.
Common problems encountered in the operation of sand washer and solutions
During the operation of sand
washing machine, customers may encounter some problems, such as the amount
of washed asnd is decreasing, the sand is leaking, the damage of sand net, bolt
ollseness, vibration of sand making machines
fixing frame, the sudden raised noise of transmission part, gear damage due to
its lack of lubrication, etc.
Here are some tips about sand making machines damage and resolution.
1). As to its bearing, the usual damage is lubrication shortage and seal ring
breakdown due to long times lacking of maintenance and cleaning. Based on some
rules, addition of lubricaiton or replacement of seal ring is necessary, among
which requent cleaning is the most important.
2). To avoid gear damage, timely maintenance is vital. Frequent oiling and
adjustment is required.
3). About the high noise of transmission part, add enough lubricating grease
if the gear gap changes. Adjust and tighten the anchor bolt of reducer.
4). The phenomena of decreased washed sand or sand leaking is mainly caused
by damage of sand net or looseness of bolt. So regular maintenance and
replacement of sand net, together with bolt tightening is necessary.
General descriptions of the ways in ore beneficiation
The common processes for ore dressing include gravity separation, flotation
separation, magnetic separation and electrical separation. The following text
will elaborate on these four methods.
A. Gravity Separation
It is an industrial method of separating minerals by the difference of their
relative density. Mineral particles of different density receive the
hydrodynamic and various mechanical force in the moving medium like water, air
and heavy liquid, causing proper loose strata and separation conditions, by
which minerals of different density are separated.
B. Flotation Separation
According to the physical and chemical differences among minerals, they can
cling on air bubbles selectively through flotation reagents disposal. The ore
dressing of nonferrous metal like copper, lead, zinc, sulphur, molybdenum, etc.
usually adopts this method.
C. Magnetic Separation
This method is based on the different minerals magnetic property. They are
separated by the different acting force in the magnetic field of magnetic separator. It
is mainly used in the separation of ferrous metal like iron, manganese,
chromium, etc. It also can be adopted in the separation of nonferrous metal and
rare mental.
D. Electrical Separation
Minerals are separated by the difference of minerals conductivity. When
minerals are in the high-voltage electric field of electricslot, due to the
different conductivity, minerals are separated by the different acting
electrostatic force. At present, it is mainly used in the separation of mixed
crude concentrate like the separation of scheelite and cassiterite, the
concentration of zircon and tantalum-niobium ores, etc.
It's necessary step to make a no load test for mining machinery
Doing anythig, there is a model. If you want to know one you pick is good or
bad, there is a necessary test. When the installation of mining machinery is
finished, a trial run, to be specific, no load test is a necessity before
leaving the factory.
Here are some requirements about this test.
1) No load running of Mining machinery should be no less than 2 hours in
series, and the machine halt should be carried out one hour late after the
bearing tempeature is steady.
2) During mining machinerys no load operation, the maximum tempeature of
rolling bearing should be no more than 75 °C, and its tempeature rise should not
exceed 35°C.
3) All moving parts should run flexibly, and any blocking should be avoided.
Pay attention to any abnoraml sound during no load test.
People need to bath to keep health, and similarly, machines also need a bath
to keep clean and prolong its life. Taking cleaning jaw crusher parts as an
example. There are mainly five cleaning methods of jaw crusher parts:
(1) Vibrative Cleaning: put parts on the cleaning basket or cleaning rack of
vibrating cleaning, and immerse them in the cleaning solution. By the cleaning
machines vibration that simulates artifical rinsing and washing movement,
together with cleaning solutions chemical effect, greasy dirt can be easily
washed off.
(2) Scrubbing: put parts in a container with diesel oil, coal oil or other
cleaning solution, wash them with cotton yarn or brush. This method is easy and
simple, but unefficient, so it is suitable for single piece small parts.
Generally, using gas is not allowd due to its lipid solubility, prone to causing
healthy problems and fire accident.
(3) Spray-wash: spray cleaning solution with some pressure and temperature
into the parts surface. This method is effcetive, but the equipment is a little
bit complicated, so it is suitable for the simple structured parts with much oil
dirt.
(4) Ultrasonic Cleaning: cleaning oil dirt by both cleaning solution and
ultrasonic oscillation.
(5) Boiling Wash: put well-compounded solution and parts into an appropriate
sized cleaning pool that is welded with steel plate. Heat it to the temperature
of 80~90 ℃, and boil it for 3~5min.

Raising the speed of rotary with excellent grinding machines by Hongxing
Now in the market, the popular and agreed grinding machine include the
ceramic ball mill,
energy-saving ball mill and rod mill. The ball mill has the advantages of
smaller size, even size and can apply to the grinding of the quartz and
feldspar. The ball mill has bigger output size so it can avoid the damage by
over crushing. So as the grinding machine, control the rotary speed is
benefit.
Each machine, each type has its certain rotary speed when it was be designed.
As all we known high speed will have high capacity. But control it to be some
certain is very important. High speed, intensified campaign, also the raw
material has its own energy, so the over crushing will be occurred in the
grinding.
Taking ball mill as an example, Type 1224. As we all known that its rotary
speed is 27-34 r/min, if we increase the speed to the 36 r/m, the capacity will
be get by 4.2%. In this condition, Capacity of the size below 5mm will increase
from 11% to 15%, and the metal will be 4% to 5.2%.
More knowledge, more news and more about the products come to Zhengzhou
Honxing Mining Machinery Co., Ltd. which is a professional manufacturer and
exporter in the mining equipment. We has strong technology, good products, and
design the processing line according to the site and requirements and realize
the concept of customer-first.
Short introduction to the tasks of impact crushers in ore beneficiation
With the pace of protection environment, the new energy-saving crusher has
been the minion of the beneficiation company, the crusher produced by the
Hengrui has several advantages :
First, it can be used on the hardness and soft materials.
Second, we can adjust the size of the products, you can adjust the size by
adjusting the rotary speed, the interval of the impact plate.
Third, the impact can deal the materials that has high moisture to forbidden
the blocking.
At last, the spare parts are cheap and low maintain cost.
What is the disease of over-broken for sand making production
When we make sand, the third generation sand making machinery
and the rod mill are main equipment, but we can also see the situation of the
over-broken. Today, the exports in Hongxing will explain it to you.
Firstly, when the rock was sent into the rod mill, we should discharge it
timely after broken. If it was grinded too long, it will be over-broken.
Secondly, the gap between the sticks are the way to protect the rock from
being over- broken, if the gap between the sticks are too narrow, the sand will
be over-broken.
Lastly, the compression strength of the rock is weaker than the stick. So the
sand was easier to be over-Broken.
Under country industrialization how to ripe all the thorns in crusher jungle
Crusher is used in mining industry in one of the most equipment, and now,
with the rapid development of our country industrialization, used mining
machinery and higher demand, so choose of high quality crusher becomes
crucial!!!!!
Although China's crushing equipment development of very good, but in the
development of our country, the crusher industry more than there will be some
problems still, these problems can directly affect the development of the
industry of our crusher, so what the problem really is plagued by the
development of the industry of crusher.
China's crusher complete products from the auxiliary tool to product change
only experience for twenty years, crusher industry was a young industry, but
also a sunny industry. But because of that, many in the industry by private and
into the mold enterprise as the main body, after 20 years of market beat up and
not a part of the success of the enterprise, but a more is in business started,
that is, in the period of capital accumulation and experience accumulation
stages, it is difficult to attend a deeper level of considered and as. Although
a lot of enterprise also have ten years, twenty years or even further to the
enterprise development planning and the grand plan, but this kind of planning
and the current situation of the mould enterprise in China and its own
developing space don't match, so more stays in theory, it is difficult to really
implementation.

costs, faster market response, the manufacturing process automation, intelligent
and improve product quality and consistency, labor strength reduction;
Thirdly, 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;
Fourthly, 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 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

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.
As to unburned ceramic what tricks played in Cement clinker production line
The production methods of Cement clinker production on unburned ceramic
including ingredients,grinding,into a ball,conservation:
a. Ingredient first been broken,and then fly ash, clinker,two water gypsums
measures l to be possible separately when feeds the ball mill.
b. Three types of raw materials in the ball mill mixing,uniform
grinding.Increase mixture of specific surface area, improve the particles of fly
ash excitation function of clinker, mixture fineness should meet 0. 080mm square
hole in under 8% of casade screen allowance, best to 3.5 per cent to 6%.
c. The particle size of the finished ball mill should be within the 5 -
20mm.Grasping the watering quantity, the feed speed, to become the spherical
segment angle, this after formation the material ball's intensity, to the
material ball initial intensity is a key especially. According to the
experiment, the watering quantity is 23.0%-27.5%, becomes spherical segment
angle 45 ~60.
d. The ceramic does not require burning or steam curing,do not need to add
any additives,but in the natural temperature conditions will feed the ball into
aggregate for conservation.
The main techniques of Cement clinker production on unburned ceramic:
a. The core of this technology is the use of silicate cement clinker
stimulate the activity of fly ash, at the same time, because of no join clinker
and plaster mixed material, its sour 2 calcium and Portland cement with
cementation sex more.
b. Gypsum can play a supporting role in stimulating and strengthening the
excitation of fly ash clinker.Choice of gypsum plaster, plaster of Paris,
chemical gypsum, waste gypsum mold. To reduce the cost, the best selection of
all kinds of waste gypsum.
c. Raw material grinding, mixing respectively to grinding the result is bad.
In the mixed grinding in each material can increase the contact, and mixture
evenly, to improve the reaction performance.
Sand dryer is a kind of equipment to dry large amounts of material.As it's
reliable operation, operating flexibility and adaptability, large capacity per

How to solve the problems affecting the life of Rotary dryer
To understand the factors which affect the service life of drying mechanical,
solve these problems, and prolong the service life of rotary dryer, HXJQ as a
rotary dryer supplier, can provide help.
A. The refractories of rotary dryer is the key factor to extend the service
life , the use length of refractories directly affect the rotary dryer's
availability.If frequently stop refractory kiln lining, it not only increased
overhaul strength, but also affect the normal operation of rotary dryer,
increasing manufacturing cost, bringing huge economic losses. The service life
of the refractory materials mainly depends on the operation status of rotary
dryer, the corresponding process, as well as refractory material selection, the
right building method. Properly laying refractory materials will be the key to
the service life of dryer, not only be helpful to prolong service life, still
can eliminate this should lead to premature damage to some of the stress; The
wrong laying method can greatly shorten the refractory materials using life.
B.Usually, the anchoring in the rotary dryer is heat-resisting steel more
than a qualitative, rivet's welding have the strict request, often should check
these parts, and change in time to ensure the the normal operation of rotary
dryer.In the construction site inspection, we often find the anchor isn't firmly
welded, sometimes even appear off phenomenon with a feet touch .if that is not
handled in time, it will appear that large area pouring materials chunks in the
production. It can cause accidents.
In the process of daily work, we should be strictly to the rotary dryer
reviews, solve the problems in time, increase production efficiency, bring
benefit to the company , as well as increase safety insurance.
In various working circumstances Hongxing Coal Slime Dryers distinguish
Coal slime dryer mainly consists of draft fan, scattered, belt device feeder,
feeding machine, rotary roller, heat source, belt discharging machine, unloaded
feeder and distribution ark to form.The work area of coal slime dryer consists
of gaide material area, lift up the stripper plate area, the material
discharging area and clean up area.
Honxing Mining Machinery is a professional rotary dryer
manufacturer, and professionaly design rotary dryer, sand dryer, coal slime
dryer, rotary kion, cement rotary dryer which have the advantage of high
capacity, perfact drying effect, low energy consumption, low cost.
A) Cleaning area: Wet coal slime in cleaning area is copy plate start to copy
form curtain material condition.Material falls easily formed wall binding
phenomenon.In the cleaning up area, for mechanical design having cleaning
device, cleaning device reasonably cleans material adhesion on the wall. In the
process, cleaning device also plays materials group ball agglomerate crushing
effect, which increases the heat transfer area, improves drying rate;
B) The material area: In this area, do not set up roller copy plate, the
material rolling taxi to discharging mouth, finish the coal slime dryer drying
process;
C) The guide material area: after wet coal slime goes into the guide material
area and high temperature hot air contact area soon a lot of coal slime water is
evaporated.In big lead angle to copy plate, coal slime can't form copy dynamic
binding and was introduced into the next working area;
D) Tilt stripper plate area: wet coal is already low moisture loose state and
don't have the binding phenomenon in this area.After heat transfer, coal slime
reach the demand water moisture, then goes to the next material area.
Hongxing advises One in A Hundred for drying plant
Do you have troubles when you want to buy a drying plant?Do you have problems
about how to select a drying plant?You must want to know which is the most
suitable dryer when you want to start a mining business. Because a reasonable
selection of drying plant can save investment, reduce running cost to ensure
product quality, get the maximum economic benefit.
The ideal selection of dryer must be according to user's conditions and
material's factor, having the stress to find the most suitable model for you
materials. The following is the general principles of drying plant
selection:
1.Before the selection of drying plant, we had better make a material drying
experiment.In-depth understanding of the drying device that the slimilar
material has used, has help for the proper selection of drying plant.
2.The dry device which is simple structure, high reliability, long service
life has a selection priority.
3.The drying plant must first can apply to specific materials and meet the
basic requirements of the dry material use, including deal with material very
well, satisfy the handling capacity, taking off the water, product quality and
some other basic requirements.
4.The drying plant must have a lower cost, including equipment depreciation,
energy dissipation, labour, maintenance, spare parts fee.
5.Low consumption.Different drying methods have different energy dissipation
indexs.Generally , energy transmission drying can reach 100% in the thermal
efficiency, while the streaming drying only about 70%.
6.Accord with environmental protection requirement, good working condition
and high safety.
7.Save investment. To complete the same function, sometimes the drying plant
can vary considerably cost.We should choose the one which is lower cost.
8. High drying rate. Just look at the drying rate, The material is highly
decentralized in hot air when we use convection drying method.And critical
moisture content is low, the drying speed is fast. With convection drying,
different dry method has differnet moisture content. The drying rate is
differnet also.
