High Pressure
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.
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 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.
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.
