High Pressure Suspension Mill can be used for ultra-fine powder processing of 280 non-inflammable and non-explosive materials with Moh’s hardness below 9.3 and moisture content below 8%, such as barite, limestone, pottery, scoria, in the work of mine, metallurgy, chemical，building materials. The particle size of finished product can be adjusted from 80-425 mesh. With the special device increased in the machine, it can produce 30-80 mesh coarse powder.

Working Process

In the mainframe of High Pressure Suspension Mill, there are strong springs with pressure as high as1000-1500 kg equipped on the roller suspender. When High Pressure Suspension 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 thel 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.

Main Characteristics

1. Compared with other mills, its capacity increases by 10%-20% under the same power condition, and compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring.

2. All the materials with Moh’s hardness below 9.3 can be grinded and smashed.
