Working Principle & Operation. The apparent difference in capacities between grindingmills(listed as being the same size) is due to the fact that there is no uniform method of designating the size of amill, for example: a 5′ x 5′Ball Millhas a working diameter of 5′ inside the liners and has 20 per cent more capacity than all otherball millsdesignated as 5′ x 5′ where the ...
