Bond Work Index Tests Grinding Solutions Ltd

The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits . The test requires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of <3.35 mm. Any screen size below 600µm can be used for the

Rapid determination of Bond rod-mill work index by

01/01/2013· The Bond rod-mill work index is used in conjunction with Bond’s third theory of comminution to merely calculate net energy requirements for sizing rod-mills. This test was originally developed in the mid 1930s by F.C. Bond. Though, it was altered in succeeding years, it has essentially remained unchanged since 1961 . To calculate the Bond work index (W i) in a standard laboratory scale rod

Testwork: Bond rod mill work index SAGMILLING.COM

The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus. The SAGMILLING.COM models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners". Most laboratories outside of Australia use the wave liner style of machine these results can safely be used in the models. Bond rod
