Aug 20, 2020. Closed circuit cement mill. The strength development of concrete is the result of the chemical reaction of water with cement particles. The reaction always starts at the surface of the cement particles. Thus larger the surface available for reaction, greater is the rate of hydration and strength development.

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.

The answer is the cement industry. Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 8090% of the raw material for the kiln feed is limestone.

Keep in mind that if feed is to be sampled from sacks, bins or feed bunks the sampling variation is increased (that is, it will be more difficult to obtain a representative sample). This increase in sampling variation is due to feed ingredient segregation. The use of a sampling probe may help to reduce some of this variation. Sample size
