2.High steady and reliability.
The gearing of Raymond mill uses Enclosed gear box and belt wheel, which is stable and reliable. Key parts are all manufactured by using premium casting and proximate matter. Exquisite technology and rigorous process makes sure the durability of the whole set device.

3.Low production cost.
The complete Raymond mill uses vertical structure, which is of small floor space and strong systematicness. From raw material rough machining, transmission, powder making to the final packing, it forms an independent production system. Compared with other powder grinding device, its sieve rate reaches up to 99%.

4.Long service life.
The quick-wear parts of Raymond mill texture uses high manganese steel, which has long service life. The motors are all national standard products.

5.No environmental pollution.
High sealing degree. During the production process, dust will not enter into the device easily and it will not produce dust easily as well, which reduces pollution. Excellent environmental protecting effect, and it is good for improving the production site environment. 
Working Principle of Superfine mineral ore grinding Raymond mill
1. After the materials are ground, the draught fan blows air into the main engine shell. Powder is blown up, and is separated by the analyzer above the grinding chamber. Materials with excessive coarse fineness fall into the grinding chamber again for grinding, and materials with standards fineness enter into the cyclone collector along with the airflow.
2. After being collected, they are discharged at the powder outlet, and becomes finished products. Airflow is recycled into the draught fan by return duct on the upper end of the big cyclone collector. The whole airflow is recycling, and flows under negative pressure condition.
3. When the air volume of the circulating airflow increases, part of the airflow is discharged through off-gas line between the draught fan and main engine. Then they enter into the small cyclone collector for purification treatment.
