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 ...

For many decades the two-compartmentball millinclosed circuitwith a high-efficiency separator has been themillof choice. In the last decade verticalmillshave taken an increasing share of the cement milling market, not least because the specific power consumption of verticalmillsis about 30% less than that ofball millsand for finely ...

Crushed ore is fed to theball millthrough the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dryball mills, theball millis charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged.
