Ball mill grinding, as a general-purpose

equipment, is widely used in mineral processing, building materials and chemical industry,

ball mushroom can be divided into two kinds of dry-wet grinding method. According to

different ways of discharge can be divided into lattice-type ball mill two overflow type.

First, the practical problems exist

1.1 mill production problems

In general, direct way to improve mill output has 3 kinds:

1 set front mill crushing machine;

2, improved grinding system to improve the grinding efficiency;
3, plus set high efficiency separator.

As we all know, the ball mill the material is broken, and then to smash the key equipment.

It is widely used in cement, silicate products, new building materials, refractories,

chemical fertilizer, black and non-ferrous metals and glass ceramics and other mineral

production industries of all kinds of ores of other grind-able materials can be dry or wet

grinding. 3 methods mentioned above, any one kind of ball ...
... mill can greatly improve yields.

Of course, if conditions permit, the factory, then supporting the use of the above 3

methods, the effect is the most ideal, which is grinding system at home and abroad in recent

years the trend. Three relationships: the premise of grinding before crushing, grinding

powder to ensure that after the election, the fundamental transformation of the
roller mill. Made before the crushing mill

grinding of materials into the particle size greatly reduced, thereby reducing the grinding

system load; separator efficiency, the most direct benefit to the maximum fine to be

finished in time chosen to reduce the cement products back to the extraction rate, reduce

the ball mill load ; the mill renovation, will improve the grinding system, the most

fundamental solution. Into the ground particle size is reduced, the powder efficiency, and

less efficient if the grinding system, affecting not only mill production, but also affect

the quality of cement mill.
1.2 The quality of cement
Cement quality, just from the grinding process, the crushing and grinding the powder before

the efficiency is not directly related. Quality inspection of concrete indicators are

generally two: the residual value of specific surface area of cement screen. But in recent

years of international quality testing indicators of cement particle size distribution of

cement, and that the residual value of the target screen surface area than cement better

reflect the real situation of the cement quality. This has caused considerable attention to

China's cement workers. Generally, the cement particles, particles less than 3μM rapid

hydration, the cement is not conducive to long-term strength, we recommend no more than 10%;

almost no activity of particles greater than 65μM, preferably no; 16-24μM particles the

highest activity. Cement production has added limestone. Limestone is not active, just a

filler, but it can improve the particle size distribution of cement products.
After the implementation of new standards of cement, cement residual value of the index

screening practice do not mean much. New standard pay more attention to some of the specific

surface area, and for the cement particle size distribution is no specific requirements.
The significance of the implementation of new cement standard cement products have greatly

improved the quality of further significance to speed up elimination of outdated, to promote

market competition, with the international cement standards for the cement industry after

China's accession to WTO to prepare for integration into the international market. As a

result, our cement plant, in particular, production of small cement plants how to improve

the quality of cement, has become an urgent problem.
Improve the quality of cement production There are many ways to adjust raw materials and

fuel ingredients programs to change firing process, strengthen equipment management, etc.,

these units need to be resolved by the production of cement, and may for a long time of

improvement, now we can do to powder cement grinding process on a small improvement to

provide effective, improved quality and yield of ball mill, faster with international

practice.
