R-type Raymond mill is a classic and widely used grinding machine. This type of Raymond roller mill is commonly applicable to over 280 kinds of non-combustible and non-explosive materials with Mohs hardness of not more than 9.3 and a humidity of less than 6%, such as barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, limestone, activated clay, activated carbon and bentonite, kaolin, cement, phosphate ore, gypsum, heat-insulating material, etc.


These materials can be used as fine powder production additive in the mineral chemical industry, construction,and other industrial fields. The finished product by the R-type Raymond miller machine can be controlled from 80-400 meshes.

Raymond Miller Structure and Working Principle

Raymond mill is mainly composed of the main body, blower, analyzer, powder collector, dust collector, pipeline device and motor. The main body refers to the frame, blade, grinding roller, grinding rings, and housing, etc.

Raymond Roller Mill Working Principle

Large block materials are crushed by jaw crusher into smaller particles within the feeding size of Raymond miller. Then the materials are sent into the storage hopper by bucket elevator machine and fed into the main grinding chamber evenly and continuously by vibrating feeder.

The finished product is taken away by the airflow of the fan. Analyzer machine will classify the powder based on set requirements. Qualified fine powder enters the large cyclone collector for separation. Lastly, the collected qualified powder is discharged through the pipe.
