Raymond mill (Raymond Grinder) machine is used
to grind barite, calcite, potash feldspar, talcum,
marble, limestone, ceram and slag below scale
7 of Moth's hardness and 280 odd sorts of non-inflammable
and non-explosive stuff in the traded of mining,
building material, chemical engineering and metallurgy
for power generation and processing. The product
size is adjustable on required in the range of
100-425 meshes.
Load the stuff for grinding evenly and continuously
into the grinding chamber of the main frame. Due
to the centrifugal force in rotation, the roller
swings outward and presses closely upon the ring.
The shovel carries the stuff to the space between
the roller and ring. When the roller rolls, the
stuff is thus grinded.
After being grinded, the stuff is to be routed
to the sorter along the wind belt of the blower
and the rough powder will be put back to the grinder
for regrinding. The fine powder flows into the
product cyclone collector together with airflow
and is expelled from the powder output pipe as
product.
In the grinding chamber, since the stuff may contain
moisture to some extent, the heat generated during
grinding makes the moisture evaporated; since
the pipeline joints are not airtight, the external
air is sucked in and the circulation air mass
increases. In order to enable the grinder to work
under negative pressures, the increased airflow
is guided to the deduster anew sequentially to
the atmosphere after purification.
