Raymond Mill

Raymond mill is used for ore preparation and coal preparation such as the fine grinding process of ore raw material, gypsum ore and coal materials. The machine consists of the host, analyzer, plumbing installation, blower, micro powder cyclone separator, while the host consists of rack, diffuser, shovel knife, grinding roll, grinding ring and housing device.

Working Principle

Grinding roller rotates under the centrifugal force. The shovel blade shovels the materials and sends them to a place between the grinding roller and grinding ring, and the materials with grinding pressure will be crushed into powder. Then the powder will be blown up by the blower to the analyzer. The powders that meet the fineness can go through the analyzer and are collected by the micro powder cyclone separator, otherwise, the powders will be returned to the grinding chamber to be ground again.

Application Range

Raymond mill is widely used in ultrafine grinding process of barite, calcite, potassium feldspar, limestone, talc, marble, dolomite and gypsum, etc. It also can do the super fine grinding process of non-flammable and non-explosive ore, chemical and construction materials with Mok’s hardness under 9.3 and humidity below 6%. The particle size of the products can be regulated within 40-400. This series of Raymond mill can be divided into high-pressure micro powder grinding mill, strong pressure suspension grinder and general Raymond mill according to the fineness and productivity of finished products.
