Raymond Mill
Raymond Grinder is suitable for producing minerals powder, which is
widely used in the fields of metallurgy, building materials,
chemical, and mining industry.
Working Process
The whole raymond grinding mill machine is collocated with jaw
crusher, elevator, hopper,electromagnetic vibrating feeder, main
unit, classifier, collector, cloth deduster and high-pressure
blower.
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.
