The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 12.7 mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is 0.305m by 0.610m, with wave liners ...
Generally, Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power. In the current research, a simple, fast and accurate procedure is introduced to find the rod-mill work index based on the conventional Bond work index.

Apr 27, 2016 The specification for the apparatus to determining a Bond rod mill work index is first described in Bond amp Maxton 1943. It states that the apparatus is a tumbling rod mill to be operated in a locked cycle test at a fixed circulating load. The geometry of the grinding chamber is described as mill inside diameter of 12 inches
