Automatic control of grinding system. According to the noise of tha ball mill, adopt the electric ear method to control the electromagnetic vibration feeding machine or belt feeding machine, and make the material of the grinding material and the automatic adjusting material uniform to join, keep the ball mill material in optimum condition, which can improve mill output. 

 

Strengthen the ventilator in the ball mill. A certain wind speed in the mill, which causes the powder to be taken away in time by the airflow, that is reducing the cushioning effect of micropowder can improve the efficiency of powder grinding and the quality of products will not be affected. The grinding speed of the mill is different from different materials, generally 0.3-1.0 m/s. When the air is well ventilated in the ball mill, the water vapor is discharged in time, the compartment is not blocked, the adhesion of the grinding body also decreases, and the temperature of the ball mill can be reduced. This is good for ball mill operation and improve product quality. High strength grade cement should be used at low speed; Instead, choose a larger speed. 

 

Water spray in the ball mill. A lot of heat is produced when ball mill grinding cement, which is bad for both cement quality and grinding efficiency, and have bad affects on production. Water is atomized and sprayed into the ball mill with high pressure air, effectively remove the heat from the ball mill to achieve the grinding cooling. Water is a surface active substance, which makes it easy for the particles to collapse to prevent the grinding of the material. The water spray in the ball mill is determined according to the temperature of the mill, usually under 1000 ℃ not spray. In addition, the amount of water spray is determined by the temperature of the ball mill, which is about 1-2% of the amount of cement. And make the water completely evaporation with no residual water. It is possible to spray water from the ball mill head or tail. When the temperature of the grinding material is high, it is better to spray water from the ball mill head, but in general, from the end of the ball mill. Water spraying in the ball mill can increase production capacity by 5% to 10%. 

 

Add the grinding aid to ball mill can improve production capacity about 10%, It's usually triethanolamine, the incorporation accounted for 0.04%-0.1% of the grinding material.
