A first survey of grinding with high-compression roller mills
Abstract. The special feature of high-compression roller mills (HC-roller mills) is that a bed of particles is compressed between two rollers to a high solid density more than 70% of volume. The size reduction occurs by interparticle crushing. The milling force must be adjusted to a level so that the particle bed is loaded by a compressive ...

Cold Rolling – Process Overview
Due to the high compression forces and friction, the temperature of each pass has the potential to reach as high as 250 °C. ... Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to 2.5 million tons of cold rolled steel annually.

Cold rolling is mainly performed by tandem mills consisting of successive mill stands. These stands gradually reduce the thickness of the strip by entraining it through friction into the roll bite, i.e. in-between their work rolls. European tandem mills were mostly built at least 30 years ago, when rather soft steel grades were cold rolled.
