High Pressure Grinding Mill

is suitable for grinding the barite, limestone, kaolnite, ceram and slags, etc. which below scale 9.3 of Mosh and below 6% shadness and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgy, chemical engineering and building material for high fine powder generating and processing .

Product size with the High Pressure Grinding Mill is adjustable in the range of 80-425 mesh. It is possible to produce 30-80 mesh coarse powder through special device in the machine.

The whole system of

High pressure Grinding Mill

consists of main frame, decelerator, classifier, piping device, blower, jaw crusher, dustpan elevator, electromagnetic vibration feeder, and electric switch box , motor, etc.

In the mainframe of the

High Pressure Grinding Mill (suspension mill）

, there are strong springs with pressure as high as1000-1500 kg equipped on the roller suspender. When the High Pressure Grinding Mill (suspension mill) works, the roller rotates around the principal axis, and clings to ring under the effect of the strong spring and eccentricity. When the materials are sent into the grinding chamber of the High Pressure Grinding Mill (suspension mill）, they are brought to the space between the roller and ring and get grinded. Then the powder grinded by the High Pressure Grinding Mill (suspension mill） 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 when the

High Pressure Grinding Mill

(suspension mill ）works.

• Compared with the common Raymond mill under the same power conditions, the capacity can be increased by 10%, under the performance of high-pressure springs, the rollers grinding pressure on raw materials can be raised by 1500kgf.
• All the mineral materials with Mohs hardness below 9.3 can be crushed.
• The final product size of the grinding mill ranges from the maximum particle diameter of 0.95mm (20mesh) to the finest diameter of 0.038mm (400 mesh). A few materials can reach 0.013mm (1000 mesh).
• Its dust-removing effect fully meets the national dust discharge standard.
• The classifier is easy for adjustment.
• The grinding machine adopts a superposition multi-grade sealing with good sealing performance.
