Grinding Media Quality Assurance For The Comminution

Comminution costs constitute mainly electricity, grinding balls and liners. Of these three components, grinding balls form the major portion of the consumable costs, and can be as high as 4045 of the total. As a result, proper grinding ball selection is a key consideration towards reducing mining costs.

BALL MILLS The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
