WFJ series air classifying mill pulverizer has been widely used for milling/pulverizing high fiber content materials, heat sensitive materials and brittle materials in food, chemical and pharmaceutical industry.
Main application:
Super-micro mill is mainly used to produce fine powder and super fine powder.This high performance equipment consists of main frame, feeding device, crushing device, discharge pipe, transmission and motor, supporting by the host, dust collector, high pressure centrifugal fan, rotary valve, whirlpool aggregator and electric control cabinet, etc. The particle size can be adjusted during operation and the fineness can be reached at 80-320 mesh. The equipment has a self-cooling function.It is widely used for material grinding in pharmaceutical, chemical, foodstuff, etc.
Working priciple:
Raw material is delivered to the grinding chamber by a screw conveyor, cut and sheared by the high speed rotating blades. Then the material is moved into the cyclone separator by means of negative pressure. No dust during operation makes it cleaner.
Main Features
1. Alloy steel hammer blades and rotor
2. GMP and food grade design
3. Negative working condition can prevent dust and be suitable for heat sensitive material pulverization.
4. Output size is adjustable via air classifier and air flow rate.
5. Feeding rate is automatic controlled
6. Particle size distribution can be accurately controlled
