The particle shape of the materials from the roller press and the vertical roller mill is also different. The vertical mill grinds the material by two forces, the extrusion force and the shearing force between the roller and the grinding disc; the roller press grinds the material by only one force, the force between the two grinding rollers.

Jan 16, 2021 · There are two main types of forces between two rolls in roller bodies. Compression force and sheer force. When adjusting rolls, rolls get close each other, in that moment, compression forces act on each rolls. This compression force is responsible for cut open the grain as well as for reduction of particle size of endosperm.
