Metal wear and grinding Dry grinding requires approximately 30 % more energy per unit weight of ground material. Consequently, dry mills need more mill volume than comparable wet mills [69a]. In Germany, an excess figure of 10 % is generally considered for dry grinding in contrast to the energy consumption for wet grinding [69b]. The increased metal wear of grinding media and …

The ball mill is used for the grinding of a wide range of materials, including coal, pigments, and felspar for pottery, and it copes with feed up to about 50 mm in size. The efficiency of grinding increases with the hold-up in the mill, until the voids between the balls are filled. Further increase in the quantity then lowers the efficiency.

1. Shell: The shell is the outer casing of the ball mill, providing structural support and containing the internal components. It is typically made of cast iron or steel to withstand the forces generated during operation. The shell is designed with thick walls to maintain its shape and prevent deformation under the weight of the grinding media and materials.
