Product Description

· Principle of Operation

The high pressure gas (air, nitrogen, other inert gases, etc.) is accelerated into a supersonic flow through the Laval nozzle and then sprayed into the crushing area to form a high speed flow field. The material particles entering the crushing zone are driven by the high speed flow field to collide with each other and crush. The crushed material is conveyed to the grading area by the rising airflow. Under the action of the high-speed rotating grading wheel, the coarse powder which does not reach the particle size requirement returns to the crushing area under the action of centrifugal force and gravity and continues to be crushed. The qualified fine powder passes through the grading wheel with the airflow and enters the high-efficiency cyclone separator to be collected. The separated dust-containing gas is filtered by the dust collector and discharged into the atmosphere or compressed again into a high-pressure gas for closed-circuit recycling after filtration.

· Technological process

Air Jet Mill

· Design Highlights

 It is suitable for the ultra-fine crushing of materials and its grading accuracy is high. Easy adjustment of particle classification particle size.
2. The interior of the pulverizer can be sprayed with tungsten carbide or lined with wear-resistant ceramics to avoid contamination by metallic impurities.
3. The pulverizer is equipped with a high precision load cell for accurate recording of incoming and outgoing material quantities.
4. It can crush materials up to Mohs hardness class 9.
5. Easy maintenance replacement of the classifier wheels and nozzles.
6. Optimization of the cavity structure and gas flow field through calculations and simulations.
7. It is suitable for automated production lines and allows for closed-cycle protective gas as well as online and remote control.
8. Noise-reducing design to reduce noise damage to humans.
9. The motor shaft end seal adopts a new combination of positive pressure gas and labyrinth seal, which effectively stops the leakage of gas dust;
10. Positive pressure air seal between the grading wheel and the discharge end to stop unqualified particles from mixing into the graded material.
