The machine is used forgrinding the barite, limestone, kaolin, cerames, ahd slags, etc,below scale 9.3 of Mohs hardness and 280-odd sorts ofnon-inflammable and non-explosive stuff in the trades of mining,metallurgical industrial, chemical engineering and buildingmaterial for high fine powder generation and processing. Theproduct size is adjustable in the range of 80-425 (1000 the finest)meshes. It is possible to product 30-80 mesh coarse powder throughspecial device in the machine.
Workingprocess:
In the main frame, a 100-1500 kg powered pressure spring is fixedto the roller suspender. After the grinder is put into effect, theroller rotates around the main shaft, and rolls closely against thering pressed by the high pressure spring and centrifugal force. Andits rolling pressure ration is 1.2 times higher than that of theraymond grinder under the same power condition and the productionoutput is raised to substantial degree.
When a certain degree of wear of roller and ring is effected, it isrecommended to adjust the length of the spring to maintain theconstant pressure between the roller and the ring. As a result, thestable output and fineness are ensured.
