What is the additional structure of Raymond Roller Mills?

Raymond roller mills are the new type equipment , which is suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 7 and humidity less than 6%. It is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, about 400 kinds of materials in total.

Structure of Raymond Roller mills

Raymond roller mills are mainly composed of main unit, analyzer, fan, dischargeing cyclone separator, powder cyclone separator and air duct. Among them, the main unit consists of frame, blow shell, shovel, grinding roller and grinding ring.

Working principle of Raymond Roller mills

The rollers tightly rolled on the ring under the effect of centrifugal force. Shovel sends material between the roller and ring and the material is grinded into powder under the high pressure.Then the fan blows the power up into the analyzer. At this time, the power material met the fineness requirement get through the analyzer and get into the power cyclone separator while the others will be sent back for re-grinding.The whole system is airtight circulation.
