2016-2-23The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm and sie a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is 0.305m by 0.305m with rounded corners a smooth lining and runs at 70rpm. The charge consists of 285 balls weighing a
