High pressure roller press as pre-grinding to ball mill

High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill. Grinding capacity of finish mill increases by about 30%. Up to capacity increases are reported in India with the use of this approach.

The typical unit of production remained the small workshop run by a single artisan helped by apprentices, using simple tools. Big factories, the "behemoth", whose history is delineated ably by Joshua Freeman in his fine book, are a recent invention. They started in Great Britain in the 18th century, although the majority were small.
