## Bond Work Index Formula-Equation

The Work Index is used when determining the size of the mill and grinding power required to produce the required ore throughput in a ball mill. 2. Procedure 2.1. Bond Ball Mill Grindability The sample was crushed to 100% passing 6 mesh (3.35mm), from this a 700 cc volume was measured and weighed to be used as feed for the Bond Mill.Orway Mineral Consultants Canada Ltd. Mississauga, ON,,Test data from the Bond ball mill work index test is used to calculate the fine grinding index (M ib). The M ia and M ib indices are used to calculate specific energy for the coarse (W a) and fine (W b) components of the total grinding specific energy at the pinion (W T) according to Equation 7. W i = 4.K.M i.[Pf(P)-Ff(F)] (6) W T = WMachining Solutions,During circle interpolations and other milling applications where a radius is generated, other factors must be accounted for. Refer to the Circle Interpolation Calculator. NOTE: For use when less than 1/2 of the diameter of milling cutter is engaged in the width of cut (WOC) and for all slotting type cutters.
