High Pressure Grinding Mill Introduction:

High Pressure Grinding Mill is a new kind of mill with high pressure. It 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 Moh’s hardness below 9.3 and moisture content below 6%, such as gypsum, barite, limestone, etc. Size of final products can be adjusted between 40-425 mesh (The fineness powder can be 1000 mesh).

High Pressure Grinding Mill Principle:

In the mainframe of the mill, there are strong springs with pressure as high as 1000-1500 kg equipped on the roller suspender.

When High Pressure Grinding Mill (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 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.

High Pressure Grinding Mill Performance Feature:

01- Compared with the traditional 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.

02- Output Size of final product can be 0.613mm (30mesh) –0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).

03- Meets the requirement of national dust-dump standard.

04- The separator can be adjusted very easily.
