Raymond mill is how to work has the working principle of Raymond mill for many people who have not been exposed to the Raymond machine industry is still very strange, I will give a brief introduction to the majority of friends.
The working principle of the Raymond mill is as follows:
The material is broken into less than 20-35mm by jaw crusher.Lift to hopper by bucket elevator.Then the belt feeder is fed into the main machine cavity for grinding.The six roller grinding devices supported on the plum blossom stand in the main engine chamber rotate around the central axis, and the roller swings outward under the action of centrifugal force.In this way, the roller compacts the ring and rotates around the roller axis.The material raised by the rotating shovel is thrown between the grinding roller and the grinding ring, and the grinding effect is achieved by the rolling of the grinding roller.
The pulverized powder is blown by the air flow of the blower to the classifier above the main machine for screening.
Fineness accord with the specification of the wind into the double cyclone collector, after the collection of the powder out of the tube is the finished product.
The granularity of finished products can be up to 400 mesh.
The purified air flows into the blower through a pipe at the top of the large cyclone collector.
The air path is circular. Except for the positive pressure from the blower to the grinding chamber, the airflow in other pipelines flows under negative pressure. The indoor sanitary conditions are good.As the water content of the material is vaporized into gas by heat during grinding, the air volume in the gas circulation air path that drains into the air pipe at the joints of each flange and the inlet of the pipeline increases.These increased air volume through the blower and the main air duct between the residual to the residual dust collector, along with the airflow into the dust collector after dust collection by the residual dust collector by the dust bag into the atmosphere.
