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.

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

When the speed of the ball mill is kept constant, the greater the filling rate of the steel ball, the more the number of blows to the material, the larger the grinding area, and the higher the grinding efficiency of the ball mill. However, if the filling rate of the steel ball is too high, the motion state of the steel ball will easily change, which will reduce the impact on large-particle

Ball Mills . For many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still.

Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill. The discharge trunnion can be furnished with trommel screen.

The ball mill has been the industry’s workhorse for over a century and despite its estimated meagre four per cent efficiency, little has changed over the years other than increases in the wear resistance of mill internals and the scale of the equipment.

3. If the rotation speed of the ball mill exceeds a certain limit (the rotation speed is very high), the steel ball rotates with the barrel without falling, and is in a centrifugal operation state. At this time, the steel ball has no impact effect, and the grinding effect is very small to stop the grinding effect.
