Introduction of Raymond mill:
Raymond Mill is the new type Raymond mill of our company, which is suitable for processing various non-flammable and non-explosive mineral materials with Moh's hardness less than 9.3 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 30 and 425 mesh. 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 mill:
Raymond mill(Rammond roller mill) is 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 mill:
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.
 

Advantages of Raymond Mill:
1. High pressure spring design.
2. Smoothly vibration reduce design
3. Convenient vane adjust design.
4. The machine has a strong material applicability , which suits for many kinds of material whose Moh’s hardness is less than 9.3.
5. Grinding device adopts superimposed multistage seal, sealed performance is good.
