Raymond Mill(Raymond Roller Mill)
is applicable to the grinding and processing of more than **0 kinds
of non-flammable and non-explosive materials with hardness less
than 7 and humidity less than 6% in mining, construction ,chemical
industry and metallurgy, such as barite, calcite, feldspar,talcum,
marble, limestone, clay, glass. The fineness of the finished
product can be adjusted from **0 mesh to **5 mesh according to
requirements. Raymond Mill Structural
Characteristics : The whole raymond grinder is of a
standing structure. Raymond Roller mill features small occupying
space and strong integration capacity. Raymond Roller mill can form
an independent production system from the lump materials , crushing
to finished powder and packaging.
All the finished particles have a good uniformity of fineness, with
passing screen rate as high as *8%. This is what other machine
cannot reach.
The machine adopts electromagnetic vibrating feeder, which ensures
even and regular feeding.Raymond mill is easy to adjust, small in
dimension, light in weight, with lower oil and power consumption
and easy to maintain.
The transmission device of the main unit is equipped with a close
gearbox which ensures its smooth transmission and reliable
operation.
Attendance of operater is not necessary in the mill operating room
because the adoption of advanced central control console
switch. Raymond Mill Working Principle: 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 go 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 classifier
along wind belt of the blower and the rough powder will be put back
to the grinder for regrinding. The fine powder flows into the
cyclone collector together with air flow and is expelled from the
powder output pipe as product.
In the grinding chamber, since the stuff contains moisture to some
extent, the heat generated during grinding makes the moisture
evaporate; 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 in negative pressure, the increased
air flow is guided to the deduster and sequentially to the
atmosphere after purification.
