Raymond mill stone milling machine advantage:
1.High output: the output of this model is improve 30%-50% higher than the output of 5R4128 Raymond machine.
2.The main engine structure is advanced: the main engine adopts the buffer device, the main engine cover structure is optimized design, the operation is stable and the noise is low; the main engine and the classify machine adopt the quick change pressing device, which is convenient for maintenance.
3.Large conveying capacity: the air blower adopts a high-pressure centrifugal fan, and the air volume and air pressure increase, which greatly improves the pneumatic conveying capacity.
4.High classification precision: the classifier adopts the built-in squirrel cage cone turbine classifier, and the finished product granularity can be adjusted arbitrarily within 80-400mesh.
5.Curved non-resistance air duct: The air duct adopts a curved non-resistance air duct design to reduce wind resistance, reduce air volume loss, and make material flow direction good, thereby increasing the analyzer's powder selection rate.
Raymond mill working principle:
Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.
Hangda mining machinery Raymond mill history:
1. have long been exported to South Korea, Vietnam, Laos, Myanmar, Malaysia, Indonesia, Peru, Colombia, Venezuela, Nigeria, Egypt and other countries.
2. 10 years history at Raymond stone milling machine in China.
