Technical principle of flat air flow pulverizer

The pulverizing mechanism of air flow pulverizer mainly determines its wide application range and high fineness of finished products Typical materials include: super hard diamond, silicon carbide, metal powder, etc., high-purity requirements: ceramic color, medicine, electronics, battery materials, fine chemicals, etc., and low-temperature requirements: medicine, food, PVC, etc By changing the common air in the air source into nitrogen, carbon dioxide and other inert gases, the machine can be used as an inert gas protection device, suitable for the crushing and grading processing of inflammable, explosive and oxidizable materials The working principle is: a complete set of pulverizing system is composed of flat air flow pulverizer, cyclone separator, dust remover and induced draft fan After filtering and drying, compressed air is injected into the crushing chamber at high speed through Laval nozzle At the intersection of multiple high-pressure air streams, the materials are crushed by repeated collision, friction and shearing The crushed materials move to the classification area with the upward air stream under the action of the fan suction Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated and conform to the particle size The required fine particles enter the cyclone separator and dust collector through the grading wheel for collection, and the coarse particles drop to the crushing area for further crushing Features of flat air crusher: 1 Suitable for ultra-fine grinding of dry and brittle materials, it is easy to obtain materials of several microns; 2 The products are not easy to be polluted and have high purity due to self grinding between powders; 3 Flat air crusher has no running parts, and other parts will not be damaged except for normal wear of lining; 4 Airtight, dust free, environmental protection; 5 Low noise, vibration free, easy to remove and wash; 6 Continuous production with large processing capacity, high automation; 7 The flat air flow pulverizer can select the corresponding lining materials (mainly around the pulverizing chamber and the inlet and outlet pipes) according to the materials of different properties, so as to solve the problems caused by the pulverizing of hard materials (Mohs hardness is not greater than 9) and sticky wall materials.
