Description
Fluidized bed jet mill is a way to achieve the dry material superfine crushing equipment with high-speed air flow. It consists of crushing nozzles. A classification rotor. The spiral feeder etc. material into the crushing chamber through the screw feeder. High pressure air through a supersonic nozzle special configuration to the crushing chamber. The material in the high speed jet flow in supersonic jet nozzle junction of acceleration. And in the repeated impact. Collision. To crushed. The crushed material with the increase of air flow into the grading chamber. The classification of the high-speed rotation of the rotor. The particle not only by the centrifugal force generated by the rotor. The classification of air flow generated viscous effects of the centripetal force. When the particles by centrifugal force is greater than the centripetal force. The classification of the coarse particle size returns the crushing chamber to impact comminution. Classification of fine particles with diameter below the gas flow into the cyclone separator. Collector to collect the gas discharged from the fan.



Principle And Characteristics
1. low power consumption. Compared with other types of jet mill energy saving 30%-40%.
2. wear small. Because the main function of grinding particle mutual impact. High speed particles rather than the collision with the wall. Suitable for crushing Mohs hardness of nine above materials.
3. Use a wide range of crushing in the range of d97=2-15um. The structure compact equipment. The internal composition. Closed-circuit comminution equipment maintenance convenient. Adopts imported frequency instrument operation. The operation of equipment to realize automatic control.
For flammable and explosive materials available. Inert gas as working medium crushing.
4. do not rise, because the materials in gas state crushing crushing cavity, so the temperature control in the normal state, the temperature will not increase.
5. no pollution, because it is the material in air driven self collision crushed, not into the medium, so in the process of crushing material does not constitute pollution.

Application
This machine is widely used in pharmaceutical medicine. Pesticides. Chemical. Metallurgy. Non metallic minerals. Talc. Barite. Kaolin. Quartz. Graphite flame retardant materials. Advanced materials. Ceramic powder material of ultrafine grinding.
