Size Reduction Visual Encyclopedia of Chemical Engineering

The hammers grind the solid against the liner 4 of the grinding chamber. The beater plates rotate between 1600 and 7000 rpm revolutions per minute to reduce the size of the incoming particles. The classifier plate 5 separates the finely ground product for exit through the discharge outlet 6 while returning oversize material back to the mill inlet through the recycle housing 7.

Particle size reduction screening and size analysis

characteristic governing size reduction is hardness because almost all mechanical size reduction techniques involve somehow creating new surface area, and this requires adding energy proportional to the bonds holding the feed particles together. A common way of expressing hardness is the Mohs scale, on which talcum is a 1 and diamond is a 10.
