What is the Bond Work Index FormulaEquation? In case you had forgotten, here is a classic: You can read all the details of this now “Biblical” grinding power requirement calculation formula in Fred Bond’s original paper. You can also review the stepbystep Bond Work Index Test Procedure I posted here.Procedure for determination of ball Bond work index,, with which the Bond test for the determination of the work index could be commenced. Thus, the number of grinding tests in the standard Bond procedure can be reduced. Thus, the number of grinding tests in the standard Bond procedure can be reduced.A quick method for bond work index approximate value,,The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial,

Introduction A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modiﬁed in 1961 (JKMRC CO., 2006).Bond Work Index Procedure and Method,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. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.
