The point where the mill becomes a centrifuge is called the Critical Speed, and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.

A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10 –t n …

A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear ...

In terms of the actual implementation, coarse and fine feeds were simulated for three different feed flow-rates (300, 600, and 1200 m 3 /h). Feed fineness was varied by keeping λ = 1.7 constant in Eq.
