Raymond mill is a kind of grinding machine widely used to grind barite, calcite, potash feldspar, talcum, marble,
limestone, cream and slug below scale 7 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.
As it is a new machine , we would like to describe its working way hereby ,Load the stuff for grinding evenly
and continuously into the grinding chamber of the main frame. Due to the centrifugal force 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 sequential atmosphere after purification.
Now a days it is becoming famous day by day, as it is cheaper than other mills and less energy consuming,
user friendly.
