First, the equipment overview: 
The machine is composed of three parts: main machine, auxiliary machine and electric control box, with a variety of performances such as air selection, no screen, no net, uniform particle size, etc., and the production process is continuous. The machine is equipped with a grading mechanism, which can make the crushing and grading complete at one time.

Second, the working principle and characteristics: 
The material enters the crushing chamber by the hopper through the screw conveyor, is crushed by the high-speed rotating blade shear, and the material is transported into the cyclone separator by the method of negative pressure wind transport, and the bag filter and the discharged material meet the requirements of the product. Negative pressure conveying makes the heat generated in the cavity during the crushing operation continuously discharged, so it is also suitable for the crushing of heat-sensitive materials.

Third, the equipment application:
This machine has a wide range of application, the production process is continuous, the particle size of the discharge is adjustable, it can handle the crushing and grading of chemicals, food, drugs, cosmetics, dyes, resins, shells and other materials, the machine has reached the international advanced level, and is widely used in the crushing of materials in pharmaceutical, chemical, food and other industries.

Fourth, the structural characteristics of the crusher:     
The structure of this machine is simple, strong, smooth operation, good crushing effect, the pulverized material can be directly discharged from the main grinding chamber, and the particle size is obtained by replacing different pore size mesh screens.
For some heat-sensitive materials, such as resin powder, white sugar, salt, etc., you can choose the water-cooled crusher produced by the company, and the temperature control effect during the crushing process is excellent.
For customers who need large-scale continuous crushing, you can choose the air-flow pulverizer prod
