High Pressure Suspension Grinder

The machine is suitable for grinding more than 280 kinds of non-inflammable and non-explosive materials with the hardness below scale 9.3 of moh’s and the moisture content below 6%, such as barite, limestone, kaolin, ceram and slags, etc, in the trades of mining, metallurgy, chemical engineering and building material for high fine powder generating and processing . 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.
In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring effected 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 condintion and the output is raised to substantial 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 seperator 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.
When a certain degree of wear of roller and ring is caused, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured.
