These ball mills are built on a steel frame, on which the complete drive is also installed. The mill runs on rubberized rollers, which are driven via torque arm speed reducers and rope drives from two standard squirrel-cage motors. The speed reducers are of standard type running in oil in dust-tight housings.

In the early 1980's, Johnson Bros. produced Z-Purlins for building sized parabolic satellite antenna receiving station discs, used around the world. They were made from 6061-T4 age hardening Aluminum. Two sizes of Purlins had to be bent with a sweep in the hard direction, for 16 different radii, that made up the frame of the dish.
When the roll diameter reduces to less than the minimum diameter required by the mill stand after turning down, then the roll is to be discarded. Stand and roll guide set-up. The goal of mill and the roll guide setup is to get the first bar rolled when changing product, on the cooling bed within the tolerance so that it is a saleable product.

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 three roll mill is composed of body, discharge plate, cooling system, rolls, baffle plate, electrical switch or electrical control system, hand wheel, transmission system, and other components. Among them, the most critical component is installed in a cast-iron frame.
