Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.

Ball mill or Rod mill or SAG or combination of any two is generally used in Alumina refineries for the purpose. The particle size of ground bauxite is decided based on the laboratory test work ranging from 149 microns to 1000 microns, however, minus 10 mesh size () has been f ound to be optimum size in most of the operative Alumina ...

The type of the ball mill used should be considered as an important factor. It is believed that roller ball milling leads to bring more contamination to the powders when compared with the roller rod mills. [8] This can be understood from the difference in the mechanisms between the two categories of mills, as previously discussed in Chapter 3.
