This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of

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.
