High
Pressure Suspension Grinder | |
|
 |
| The machine is suitable
for grinding the barite, limestone, kaollnite, 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 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 asubstant 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. |  |
