High Pressure Grinding Mill

Zenith High Pressure Mill is mainly applied to the powder processing of mineral products in the industries of metallurgy, construction materials, chemical, and mining, etc. It can produce powder from various non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as barite, limestone, kaolnite, ceram and slags, etc. The Product size 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 if necessary.

A 100-1500 kg powered pressure spring is fixed to the roller suspender in the main frame. The roller rotates around the main shaft after the grinder is put into effect, and rolls closely against the ring affected by the high pressure spring and centrifugal force. And its rolling pressure is 1.2 times higher than that of the Raymond grinder under the same power condition and the output is raised to a new degree. When the stuff is loaded into the grinding cavity, it is shoveled into the space between the roller and the ring for grinding. The resulted powder is routed to the separator along the circulation wind of the blower and the standard fine powder is guided to the cyclone collector as final product and large size stuff falls back to the grinder for regrinding. The circulation wind returns to the blower to repeat the above process and the remainder wind enters into bag deduster for purification.

If there is some wear on the roller and ring, it is recommended to adjust the length of the spring to maintain the previous pressure between the roller and the ring, and the stable output and fineness are kept.
