Aball millis an important tool in the material handling industry. It is used to grind, blend or even mix materials. There are many tools available to designball mills. Most use an empirical approach developed from the extensive research into theoperationof aball mill.
At the same time, end miller, arc miller and ball miller are respectively selected in the software. So there are totally 9 simulations of the milling process that are performed. Then the experimental cutting processes are performed correspondingly and the surface roughness and the accuracy are measured.
Theball millsare often applied in mineral processing, they are e.g. an important part of the cement industry. A key factor, which influences themillingprocess, is the granular flow of grinding media. The flow determines: energy consumption, time ofmillingand capacity; thus there is a need to describe the phenomenon. The discrete element method - DEM is a computational method, which ...
