High efficiency used for 200mesh plaster Raymond Grinder Mill

Product Overview

Description

High efficiency used for 200mesh plaster Raymond Grinder Mill 

Raymond mill is suitable for powder making of more than 280 materials in mining, building material and chemical industry. They are non-flammable and non-explosive materials with humidity less than 6% and Moh`s hardness less than 7, such as barite, calcite, 

feldspar, limestone, marble, glass and so on.

 

 

Working principle of Limestone grinding machine Raymond mill:

 

In the mainframe of Raymond Mill, there are strong springs with pressure as high as1000-1500 kg equipped on the roller suspender. When Raymond Mill works, the roller rotates around the principal axis, and clings to ring under the effect of the strong spring and eccentricity. Its press is 1.2 times of Raymond mill under the same press condition, so the production is largely increased. When the materials are sent into the grinding chamber, they are brought to the space between the roller and ring and get grinded. Then the powder grinded will be blown into separator. The fine powder after departed with the air is discharged through the outlet as final product. The large-sized powder falls back for regrinding. The air will be back to the blower for repetition of the above process. The left air wil come to the bag filter to get cleaned. When the wear and tear between roller and the ring reaches certain degree, adjust the length of the strong spring,, so to keep the invariable pressure between the roller and the ring, to make sure the stable production and the fineness.
