Vertical Roller Mills The roller grinding mill technology, patented in 1928 and continuously developed since then has become synonymous with Loesche's pioneering engineering and know-how. The material to be ground is crushed between the rotating grinding .
tion of compressive and shear stress right through to shear-free grinding, or pure compressive comminution. The grinding material is comminuted in the Loesche mill between the rotating grinding track and the stationary grinding rollers. There are two basic types of roller axis position in relation to the centre of rotation of the grinding plate.
Vertical roller mill is a kind of grinding machine for cement raw material, cement clinker, slag and coal slag. It has the features of simple structure, low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.

roller grinding mill between the rotating horizontal grinding track and the stationary grinding rollers. Grinding is effected primarily by compression. A certain amount of shear force increases the quantity of fine particles in the grinding material. This effect is created by tapered rollers, whose axes are angled
I see that several have answered based on dry grinding, i.e. Vertical Roller Mill vs. conventional Ball Mill. If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies.
