    botswana ball mill feeding process. ball mills are the most effective laboratory mills for rapid batchwise comminution of mediumhard soft brittle fibrous temperaturesensitive and moist samples down to the finest particle size the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding,grinding media wear rate calculation in ball mill,in any mill, the rate at which the surface of any ball decreases is proportional to its surface. since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. this is seen to be kick’s law.
