High Pressure Grinding Mill Specifications:
High Pressure Grinding Mill is a new kind of mill, which is invented with great concentration and on the basis of many years of powder processing experiences. This invention starts an epoch of high efficiency and low cost in international mining industry. High Pressure Grinding Mill can be used to grind non-inflammable and non-explosive materials with Mohs hardness below 9.3 and moisture content below 6%, such as barite, limestone, pottery, and scoria. Size of final products can be adjusted between 80-425 mesh (The fineness can reach 1000 mesh). High Pressure Grinding Mill can produce coarse powder between 30-80 mesh by adding special equipment. This machine is widely used in the fields like mining, chemical industry, construction materials, metallurgy, etc.

High Pressure Grinding Mill Features:
1. Having higher capacity of 20-30% relatively to Raymond mill, and Higher grinding force of rollers to stuffs because of high pressure springs.( notes for 5R4121: compared to 5R4119 Raymond mill, at the same motor powder, capacity is improved to 10%, and Higher grinding force of rollers to stuffs because of high pressure springs.)

2. It can process the mineral stuffs of Moh's hardness below 9.3 grades.

3. The final products have a wide range, max? powders are up to 0.95mm (20mesh), mini ones are 0.038mm(400mesh). little pollution and dust collector efficiency is to national limitation.

High Pressure Grinding Mill Working Principle:
??? In the mainframe of High Pressure Grinding Mill, there are strong springs with pressure as high as1000-1500 kg equipped on the roller suspender. When High Pressure Grinding 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 will 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.

High Pressure Grinding Mill 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. Size of final product can be 0.613mm (30mesh) 0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).

3. High Pressure Suspension Mill meets the requirement of national dust-dump standard.

4. The separator can be adjusted very easily.

5. The multi-class seals are adopted to keep the grinding equipment tightly closed.
