The fluidized bed airflow pulverizer is a kind of high-speed airflow to realize the ultrafine grinding of dry material. It is composed of crushing nozzle, graded rotor, screw feeder and so on. The material enters the crushing chamber through the screw feeder, special configuration of the supersonic nozzle to the crushing chamber high-speed jet, the material in the supersonic nozzle jet acceleration, and repeated in the nozzle interchange, collision, to crush. The particles are subjected to the centrifugal force generated by the graded rotor and the centripetal force generated by the viscosity of the air flow. When the particles are subjected to centrifugal force greater than the centripetal force, the coarse particles above the grading diameter are returned to the crushed material. Room to continue the impact of crushing, grading below the fine particles with the air into the cyclone separator, collector collection, the gas discharged by the fan.
Characteristic:
1.Low energy consumption, compared with other types of jet mill saving 30% -40%
2.Low wear, because the main crushing effect is the particles collide with each other, high-speed particles and wall rarely collision, can be applied to crush Mohs hardness of more than nine materials.
3.No pollution, because the material is driven by the air under the collision of their own crush, not into the media, so that the material in the crushing process will not constitute pollution
4.Does not increase the temperature, because the material is in the state of gas expansion, so the crushing chamber temperature control at room temperature, the temperature will not rise
On the flammable and explosive materials can be used for inert gas rushing.
Application
The machine is widely used in western medicine, Chinese medicine, pesticide, chemical, metallurgy, non-metallic mineral, talc, barite, kaolin, qu
artz, graphite, flame retardant materials, advanced materials, ceramics and other dry powder
