Description
Description of Raymond Grinder:
Raymond Grinder (Raymond Mill) is used to
grind barite, calcite, potash feldspar, talcum, marble, limestone,
ceram and slag below scale 7 of Moth's hardness and ***-odd sorts
of non-inflammable and non-explosive stuff in the trades of
mining, building material, chemical engineering and metallurgy for
powder generation and processing. The product size is adjustable on
required in the range of *****5 meshes. Some of the materials
up to ***0 mesh.
Structural characteristics:
The whole grinding mill is of a standing
structure, all the finished particles, have a good uniformity of
fineness, with passing screen rate as high as *8%.
Functional process of Raymond Grinder:
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 to reginding. 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.
