Rod mills, how they function. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers.

4.2.3.1.1 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.

The major factor determining the design of a rolling mill is the mill's function relative to the range of production or the technological process. Based on the range of production, rolling mills are divided into billet mills (including mills that roll slabs and blooms), sheet and band mills, section mills (including beam and wire mills), and ...
