The vertical ball mill is used for the processing of refined cocoa liquor. This machine is used to further refine the preground cocoa liquor which comes from the beater blade mill or singlestone mill at the initial stage. The vertical ball mill can be used in a 2 – 4 stage refining system, with 1 – 3 ball mills in a sequential row after the pregrinder.

Get Price### The operating principle of the ball mill

The operating principle of the ball mill consists of following steps. In a continuously operating ball 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. Then, discharge of ground material performed through the central hole .
