### US4605309A - Mixing and shearing roller-mill - Google

A roller-mill for mixing and plasticizing materials, comprises two tempered, rotatable rollers which are operable at different circumferential speeds. The rolls are long and are provided with angular grooves which are inclinedly disposed relative to the axis of rotation of the rolls. The grooves on the two rolls extend in opposite directions to one another.

Shearing stresses produces grinding action on the clinker. A grinding force is transmitted to a set of three rollers at 120 Degree apart through a hydraulic system. The table and rollers then grind the material, which is then extracted from the VRPM by gravity and a little help from a scrapper.

2019-2-4 Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring.
