Cement clinker ball mill Cement clinker ball mill application Ball mill is the key equipment to grind after the material was crushed. Ball mill is widely used in grinding clinker, carbonate, fireproof stuff, and chemical materials, ball mill also can be used in beneficiation industry to grind the ores before selection.

The grinding sound of the mill is too clear and harsh. The grinding sound value of the electric ear is 158 dB, which is obviously higher than the normal 120 dB standard. It is fully explained that the mill load is too small, the feed quantity is too small, and the steel ball impacts the liner for a long time, resulting in fracture.

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

2) The material grinding adopts the company's large-scale ball mill equipment with a tube diameter of 4.2 meters and an hourly output of 85t cement, which is a professional cement production grinding equipment. The combined use of the ball mill and the crusher pre-crushing system can give full play to the grinding effect of the ball mill.
