Product Details

Raymond Mill is a classic and widely used industrial grinding equipment. It is mainly designed for processing non-flammable, non-explosive and brittle materials with Mohs hardness below 9.3 and humidity below 6%. The equipment features compact structure, stable operation and high grinding efficiency, serving as a core device in the powder processing industry.

Large bulk materials crushed by the jaw crusher to the needed size are fed into the storage hopper by a mine hoist and then fed into a grinding chamber of main engine uniformly, quantitatively and continuously by a electromagnetic vibrating feeder for grinding. Grinded materials are blown into separator by blower for classification. With the function of impellers in the separator, materials without meeting the requirements of the fineness are fallen into a grinding chamber for grinding again; materials meeting the requirements of the fineness are blown into a cyclone powder collector with airflow through pipelines for separation and collection. The powder from a discharging device is the finished product. Separated airflow is back to blower through return duct on the top of the cyclone powder collector.

Product Advantage

  • Force produced from milling roller connected by the pull rod and the high pressure spring can avoid damages caused by bulk materials to the equipment;

  • Resilient coupling between the main engine and separator can reduce the vibration and noise and improve the service life of equipment. Because of connecting crushing, drying, grinding, classifying and transmission together with the simple system and compact layout, it covers about 50% of the area of the ball mill system and can be outdoor arrangement, which can reduce the investment cost a lot;

  • Milling roller devices adopt superimposed multistage seal with excellent seal performance. Unique air circulation system with advanced dust remover carries the environmental protection concept through to the end;

  • Impeller devices with high density and high precision increase more than 50% of finished product yield under the same power. Efficient and energy-saving centrifugal induced draft fans improve the efficiency of induced draft fans greatly. Convenient impeller adjusting devices improve the precision of the finished product.
