Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.

This is to ensure a return of 51.85 percent for milling copra and 57.73 percent for ball copra over the all India weighted average cost of production. The increase in MSP for copra for 2022 season is in line with the principle of fixing the MSP at a level of at least 1.5 times the all India weighted average cost of production as announced by the Government in the Budget 2018-19.

Ball milling enables high-solids slurry to maintain low viscosity and yield stress while obtaining a non-toxic high-concentration fermentable syrup, which is undoubtedly of great significance for inter-unit processing, mixing and downstream process. In addition, the energy input for ball milling could be balanced by the reduced mixing energy.
