1 Calculation ofball mill capacity. The productioncapacityof theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the productioncapacityof theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
1)Rod milling– a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit.
Mar 09, 2016· Re: motor selection for ball mill. @ BradtheRad, The jar should be rotating 80 rpm but the shaft should rotate faster than this. The Jar will be 10 times the diameter of the steel rod connected to the shaft of the motor. this means the motor should rotate 10 times the jar = 10 *80 rpm=800 rpm...

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.
