In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Difference between grinding and milling The abrasive grains in the wheel are much smaller and more numerous than the teeth on a milling cutter. Cutting speeds in grinding are much higher than in milling. The abrasive grits in a grinding wheel are randomly oriented . A grinding wheel is self-sharpening.

between balls and raceway occurs in non-rotating ball bearings that are subject to external vibration. When the bearing isn't turning, an oil film cannot be formed to prevent ~rina~ ~mks raceway wear. Wear debris oxidizes and accelerates the wear process. Correct by isolating bearings from external vibration, and using greases containing antiwear
Table of ContentsBall Mill Equipment and SpecimensBall Mill ProcedureBall Mill Results and Discussion When a lump of ore is crushed by the impact between two balls in a ball mill, it is considered high-stress, three-body abrasive wear. The abrasive wear of balls that results from the milling of ore is the major wear loss in most minerals processing plants.
