The basic objective of grinding of bauxite is to increase the surface area of material substantially so as to improve its reactivity with caustic soda to a desired level during digestion process. As such wet grinding of bauxite has been found to be energy efficient and environment friendly as well. Ball mill or Rod mill or SAG or combination of ...

The speed of mills depends upon their diameter; a ballmill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times. Tubemills run at a revolution or two faster (see Fig. 117). Some ores require much finer grinding than others to liberate the minerals, and this increases the milling cost. Ball Mill Product Classifying
