Grinding Aids for Ball Mills Industrial Efficiency ...

A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill. A grinding aid prevents ...

The clinker is ground by conventional ball mill grinding with the present grinding aid composition. In continuous processes, the clinker can be pretreated, such as by spraying and the like, prior to entering the grinding zone. The resultant material is classified by particle size and the desired product is removed.

Effect of grinding aids in cement grinding

requires more energy and reduces capacity. The economic alternative is to use a grinding aid. Grinding aid or grinding additives refer to substa nces which when mixed into the mill contents cause an increase in rate of size reduction and flowability. Grinding process of clinker was carried on with a laboratory scale ball mill by varying ...

The variation of “k” parameter with ball mill feed rate and grinding aid dosage The m values were equal to each other for the tests performed in the same period. m parameters were calculated for GA-1, GA-2 and GA-3 as 0.72, 0.65 and 0.63 respectively.

Effects of grinding aid dosage on circuit performance and ...

In this study, the effects of GA on transportation rate of the ground material inside the cement ball mill and the effects of this change on the whole grinding circuit were investigated. In this context, industrial tests were carried out with three different dosages of an amine-based commercial GA in a closed-circuit cement ball mill.
