How Is The Capacity Of Ball Mill Determined In Afghanistan

Ball Mills Mineral Processing Metallurgy Working Principle Operation The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the

Calculate Ball Mill Grinding Capacity The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent It is especially difficult to teach mill
