Detailed Product Description

The machine is used for grinding the barite, limestone, kaolin, cerames, ahd slags,
etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and
non-explosive stuff in the trades of mining, metallurgical industrial, chemical
engineering and building material for high fine powder generation and processing.
The product size is adjustable in the range of 80-425 meshes. It is possible
to product 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 pressed by the high pressure spring
and centrifugal force. And its rolling pressure ration is 1.2 times higher
than that of the raymond grinder under the same power condition and the production
output is raised to substantial degree .
When a certain degree of wear of roller and ring is effected, 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.
