The most common grinders are the hammer mills and the roller mills.they have been applied to the task of particle size reduction or grinding in feed milling applications. roller mills have been used in the processing of common feed materials for years. the earliest roller mills used in the feed milling were abandoned flour milling roll stands, used primarily to produce coarse granulations of grinding mill.

Pressing operation is important for the capacity and economy of a paper machine and has great influence on paper quality. it determines the dryness of the sheet entering the dryer section. it has a major impact on the structure and runnability of the paper and thus the operating efficiency of the machine wahlstrom, 1969.

The purpose of the primary crusher is to reduce the rom ore to a size amenable for feeding the secondary crusher or the sag mill grinding circuit. the ratio of reduction through a primary crusher can be up to about 8:1. feed: rom up to 1.5 m. product: -300mm for transport to -200mm for sag millgrinding mill. roll mills. the roll mill is the simplest batch mixing equipment. the principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. the ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

A three roll mill or triple roll mill is a machine that uses shear force created by three horizontallygrinding mill relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into itgrinding mill. operation of a three roll millgrinding mill nip experiences very high shear force due to the different rotation speeds of the two rolls.
