Bond index ball mill rod mill bt 100 xl. The optimum number of grinding balls is 285 however the ball diameters vary due to wear therefore the total ball number should be adjusted from time to time to ensure a total mass of 20125 grams the grinding jar of the bond index ball mill measures.
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.
