Bond Impact Crushing Work Index -Procedure and Table

2015-6-16  The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers)

Bond Work Index Tests Grinding Solutions Ltd

The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers. The open and closed sized settings for given product sizes can also be determined.
