Ball Mills use grinding media in spherical or cylindrical shapes in rotating containers to grind a wide range of material types to very fine sizes. Jars and grinding media are available in a wide variety of material types to optimize performance characteristics for long-term wear-resistance, low contamination levels, or economical operation.
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.
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples.
