Raymond Mill, Raymond Grinder, Raymond Grinding Mill, Raymond Roller Mill: PulverizerRaymond Mill is suitable for chemical industry like rubber, pesticides, enamel, paint, phosphate fertilizer, paper. Hardness in the Mohs seven following humidity below 6% non-flammable and explosive materials. Such as: Talc, barite, calcite, limestone, manganese ore, iron ore soil, chrome ore, quartz, gypsum, bentonite, etcceramics, etc. With qualified products and good service, Hengda supplies series Raymond roller mill (Raymond mill)Working Principle of Raymond Mill: First material should be crushed into the desired size by Jaw Crusher, and delivered to the Silo by Bucket Elevator. Our Designed Vibrating Feeder will feed the material into the grinding room. With the air current from the Air Blower, those powder conforms to the fineness degree will be blew into the cyclone collector and those powder that is not consistent with the desired size will return to the grinding room to be re-ground. The whole system is airtight circulation, and the circulatory flow under the negative pressure. Raymond Mill features: 1. Three-dimensional structure2. Land-saving3. The screen-passing rate can reach to 99%4. The transmission is steady and reliable; 5. The transmission device of mainframe adopts airtight gear case and zonal wheel. 6. Centralized control for the electric system, convenient to operate
