Roll Mill - an overview | ScienceDirect Topics

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.

Principles of Metal Manufacturing Processes | ScienceDirect

The manufacture of can body stock includes both hot and cold rolling. Hot rolling usually utilizes an integrated hot line. The breakdown mill is usually a four-high mill capable of reversing direction. The ingot is passed back and forth through the mill about 15 times, causing a reduction in thickness from about 60 cm to about 4 cm.
