The airflow crushing classifier is a new type of equipment developed on the basis of the original airflow mill for the production process and characteristics of the polishing powder. The model uses the fluid mechanics software developed by our technical research institute to calculate the most suitable flow. Field, the most ideal pressure distribution to guide the design, breaking through the particle acceleration technology, greatly improving the pulverization efficiency and reducing the energy consumption; the material is driven by the supersonic flow to make the particles collide with each other, friction to crush, the material will not Collision and friction directly with the inner wall of the equipment, thereby effectively reducing the secondary pollution of materials during the production process and ensuring the purity of the product.
How the jet mill works
The airflow pulverizer and the cyclone separator, the dust collector and the induced draft fan form a complete set of pulverizing system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber at high speed through the Laval nozzle. At the intersection of the multiple high-pressure air streams, the material is repeatedly crushed, rubbed, sheared and crushed, and the crushed material rises under the action of the fan. The airflow moves to the classification zone, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles meeting the particle size requirements are collected by the classification wheel into the cyclone separator and the dust collector, and the coarse particles are lowered to the crushing zone to continue to be crushed. .
Airflow mill application
The pulverization mechanism that is mainly applied to the jet mill determines its wide application range and high fineness of finished products. Typical materials are: super-hard diamond, silicon carbide, metal powder, etc. High-purity requirements: ceramic pigments, medicine, Biochemical, etc., low temperature requirements: medicine, PVC. By changing the ordinary air of the gas source part into an inert gas such as nitrogen or carbon dioxide gas, the machine can be used as an inert gas protection device, and is suitable for crushing and classifying processing of flammable, explosive, and easily oxidizable materials. Widely used in chemical, mineral, metallurgy, abrasives, ceramics, refractory materials, medicines, pesticides, food, health products, new materials and other industries.
