Ball Mill: Operating principles components Uses

The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; Residence time of the material in the mill chamber. The size, density and number of the balls.

Particle size reduction screening and size analysis

Impact mills use revolving hammers to strike incoming particles and to break or fling them against the machine case. In jet mills, particles strike each other as they are transported in a stream of air or steam. For the initial reduction of large materials, a rotating drum propels the feed into the air where the pieces strike each other and fracture.
