Thecapacity, or throughput, of aball mill, is directly linked to particle size of theball milldischarge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. Establishing a commercial liberation size is critical when designing and engineering yourgrinding circuit.
Working Principle & Operation. The apparent difference in capacities betweengrinding mills(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 20percent morecapacitythan all otherball millsdesignated as 5′ x 5′ where the ...
