How does raymond mill work? Here is the the working principle of raymond mill as below:

The whole structure of Raymond mill is composed of a Main unit machine,Driving system, Classifier, pipeline device, blower, finished cyclone separator, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric motor and other components. The Main machine is composed of a machine frame, Raymond mill inlet volute, blade, grinding roller, grinding ring, a cover casing and a motor.

the working principle of raymond mill

The bulk materials by jaw crusher to the desired size, by the elevator will be the materials to the storage hopper, then after vibrating feeder evenly and quantitatively and continuously into the indoor Main machine grinding, grinded powder was blow by airflow away. Through the Classifier grading, consistent with the powder fineness with air flow through the pipeline into the cyclone collector, were isolated and collected, and then by the powder in tube is discharged into the finished powder. Air flow from large cyclone collector is arranged at the upper end of the air return pipe suction blower. The air current of the whole system is a closed loop, and flow circulation in the positive and negative pressure condition.

In the grinding chamber internal was grinding material has certain water content, grinding heat is generated resulting in grinding indoor gas evaporation changes the gas flow rate, as well as the whole all the pipe connection is not tight so that the external gas is inhaled, the circulating air flow volume increased, as is this by adjusting the fan and the host computer are the pipe to achieve the flow balance, and gas is introduced into the small cyclone collector excess, the residual gas into fine powder collecting down, then the cyclone collector upper exhaust pipe into the atmosphere, or into the dust collector in the exhaust gas purification.
