What type of mill is a Raymond mill?
Raymon mill also known as Raymond grinding mill, Raymond roller mill and Raymond grinder. Is suitable for grinding non-flammable and non-explosive materials. The finished powder size can be adjusted between 30-425 mesh(0.613mm-0.044mm)
The raymond grinding mill is widely used in such small and medium industries as mining, chemicals, building materials, metallurgy, refractories, pharmaceuticals, cement, etc. It can be used in grinding of quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore,slag, carborundum, bauxite, rock phosphate, coal , etc.

Features of Raymond Mills
1. High efficiency and precision classifier, unique airtightness, which canensure the quality of end products.
2. The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss and avoid air energy loss.
3. The bevel gear overall dive can achieve higher transmission efficiency, easy to install and adjust, long service life and lower cost.
4. Convenient repaire and maintenance.
5. Long service life.
How does a Raymond roller mill work?
After the materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust filter.
