Bond Tests Mining SGS

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.

Bond Work Index Procedure and Method

2019-10-24  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. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

Bond Work Index Formula-Equation

Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack EnergyThe basic index equation is:W = 10 Wi/√P  10 Wi/√F(1)where W is the input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the index, or the grinding resistance parameter. It represents the energy input required in kilowatt hours to reduce a short ton from theoretically infinite feed size to 80% passing 100 microns. Thi
