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.
The traditional impact work index Wi proposed by Fred Bond over 60 year ago is still used today in characterizing material crushability.
