In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.

This minimizes grinding work of ball mills or may completely eliminate ball milling. Dry Finish Grinding The greatest power savings can be achieved if the high-pressure grinding roll is used in closed circuit mode for finish grinding. Savings of up to 50% are possible in comparison with conventional tube mill systems.

How ball mills work. A ball mill grinds material by rotating a cylinder filled with media (typically metallic or ceramic balls) mixed with a continuous flow of feed and recycled material. At slower rotational speeds, the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated.
