Micro Grinding Mill

Micro grinding mill is suitable for grinding the barite, limestone, kaolnite, ceram and slags, etc. which below scale 9.3 of Moth 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 . The Product size is adjustable in the range of 80-425 mesh. The micro grinding mill is possible to produce 30-80 mesh coarse powder through special device in the machine.

micro grinding mill working process

In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the hammer mill is put into effect, the roller rotates around the main shaft, 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 micro grinding mill 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, The micro grinding mill 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.
