The operating principle of the ball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
Jul 01, 2003· Energy Density = InstalledMotorPower (kW)MillChamber Volume (liters) Since coolingcapacitydictates the installedmotorpower, by comparing the energy density of each mediamilltype, it is clear to see which ones have the most cooling capability to allow for the maximum grindingcapacity.
Themillproduct can either be finished size ready for processing, or an intermediate size ready for final grinding in a rodmill,ball millor pebblemill. AG/SAGmillscan accomplish the same size reduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of aball mill.
