Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

The Contraplex is a fine impact mill with two driven pin discs. In counterrotating mode, much higher relative speeds are possible than with the UPZ fine impact mill with only one driven pin disc. The highest relative speed develops at the outermost pin rows and can be up to 240 m/s. The fineness can be adjusted by altering the pin disc speeds.

It was found that the ball mill consumed kWh/t energy to reduce the F 80 feed size of µm to P 80 product size of µm while stirred mill consumed kWh/t of energy to produce the product size of µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
