Force produced from milling roller connected by pull rod and high pressure spring can avoid damages caused by bulk materials to the equipment.
Resilient coupling between main engine and the separator can reduce vibration and noise and improve service life of the equipment. Because of connecting crushing, drying, grinding, classifying and transmission together with 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.

Large bulk materials crushed by jaw crusher to the needed size are fed into storage hopper by mine hoist and then fed into grinding chamber of main engine uniformly, quantitatively and continuously by 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 grinding chamber for grinding again; materials meeting the requirements of the fineness are blown into cyclone powder collector with airflow through pipelines for separation and collection. Powder from discharging device is the finished product. Separated airflow is back to blower through return duct on the top of the cyclone powder collector.
In a dry grinding process, the concentrator selected autogenous mill firstly, which caused serious equipment loss, the efficiency is not high and the discharging granularity is much more than expected granularity. In this case, the customer adopted raymond mill finally. Raymond mill is an ideal equipment for dry milling, which has a higher efficiency than ball mill. It has low power consumption, small tear strength, and uniform discharge. The most important thing is that Raymond mill integrates crushing, grinding and classification together, the system is simple, and it adopts the impeller device, the discharge particle size is small, not only improved the production capacity, but also reduced the investment cost, the customer satisfaction is satisfied with the result.
