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.
ore sample will be tested in a standard Bond ball mill grindability test (aka. the Bond ball mill work index test) with a closing screen size chosen so the test product P80 closely matches the survey product P80. Depending on the plant configuration, it may be possible to also collect this raw ore sample without shutting down any grinding mills.
