Aug 23, 2019· There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.Key properties of grinding mediaaresize,density,hardness, andcomposition.
Ball mill can be dry or wet grinding for all kinds of ores and other materials that may be ground. It is widely used in mineral processing, building materials and chemical industry, etc. Ball mill can be divided into two kinds of grinding ways:dry and wet.

a)Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the …
Better efficiency, starts with better grinding. You’ve already gone through the work to bring the ore to the mill, now it’s time to recover as much precious metal as possible.GrindingExpert™ automatically adjust feed rate,mill speed and water addition to reduce upsets,eliminate grind-outs and increase tonnage in SAG / ball mills.
Ore Grinding Mill THEORY BALL AND TUBE MILLS Grinding Action INSIDE Mill. The grinding that takes place in mills of this type isusually ascribed to two actions,impact and attrition, although some authors do not believe that a sharp line of demarcation can be drawn between the two actions.
Mill sizing for most grinding installations is usually arrived at through calculations involving requiredthroughput,ore work index estimates, andfeed and product size-distribution requirements. This information is then tempered with experience to arrive at actual mill size recommendations.
Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The requiredproduct size distribution is to be 80% passing 100 mesh (149 microns).
