VRPM – AMCL Machinery Limited
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.

Shear Stress: Definition, How it Works, Example, and …
Shear force is an internal force generated by an applied load. It is typically depicted in shear diagrams for different sections along a structural member and appears as a pair of vector forces of equal magnitude but opposite directions. Shear stress, on the other hand, is a measure of the intensity of this force distributed over a unit area.
