The grinding system is automatically controlled. According to the noise of the ball mill , the electric vibrating feeder or the belt feeder is controlled by the electric ear method, and the proper amount of the material in the grinding machine and the automatic adjustment of the material are uniformly added, so that the material amount in the grinding is always maintained at an optimum state, which can increase the mill output.
Strengthen the ventilation inside the ball mill.
The mill has a certain wind speed, so that the fine powder generated during the grinding process can be taken away by the airflow in time, which reduces the buffering effect of the fine powder, can improve the grinding efficiency, and the product quality is not affected.
The ventilation speed in the mill varies with different materials, generally 0.3-1.0 m/s.
When the ventilation is good, the water vapor in the grinding machine is discharged in time, the pores of the partition plate are not blocked, the adhesion phenomenon of the grinding body is also reduced, and the temperature inside the grinding machine can be lowered, which is beneficial to the operation of the mill and the improvement of the product quality.
For the production of high-strength grade cement, low speed should be used; otherwise, a larger speed should be used.
Spray water in the ball mill.
A lot of heat is generated when grinding cement, which is unfavorable for cement quality and grinding efficiency, and affects production.
The water is sprayed into the mill by high-pressure air, effectively taking away the heat inside the mill and achieving internal cooling in the mill.
Water is a surface active material, which easily disintegrates the agglomerates of the particles and prevents the inclusion of the abrasive.
The water spray in the mill is determined according to the temperature inside the mill, and generally does not spray water below 1000 °C.
In addition, the amount of water spray depends on the temperature of the clinker, which accounts for about 1% to 2% of the amount of cement, and completely evaporates the water injected into the mill without leaving moisture.
It can be sprayed from the grinding head or sprayed with water. When the temperature of the milled material is very high, it is advantageous to spray water from the grinding head, and in general, it is sprayed from the tail.
Water spray in the mill can increase production capacity by 5%-10%.
Adding grinding aid to the mill mill can increase the production capacity by about 10%. Generally, triethanolamine is used, and the blending amount accounts for 0.04%-0.1% of the milled material.
