Raymond Roller Mills are unversal grinding machine for up to 280 kinds of minerals such as limestone, gypsum, bentonite, talc, feldspar, calcium carbonate, barite, etc.

Raymond Roller Mills are widely used in many industried for making the mineral powder, and the mineral powder size can be from 40 mesh to 325 mesh, some fine powder size can be up to 1000 mesh.

Raymond Roller Mills working principle is as below：

◆Raw material is crushed by jaw crusher to the size required which is suitable for theRaymond Mill (Grinding Mill),

◆Then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feederevenly and continuously into the grinding chamber for grinding mill. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind.
