Bond Work Index Tests. Grinding Solutions offers a range of Bond Work Index Testing from crushability and abrasion to ball and rod mills. For more information on the tests please see below Bond Low Energy Impact Test. The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi) also known as the Impact Work Index.

How hard a ball mill operator has to work depends partly on himself and partly on the kind of muck the mine sends over to the mill. In some plants the ore may change two or three times a shift and a ball mill operator has to keep on his toes.

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
