Do you know the function of air jet mill? EPIC Powder Machinery

With the development of society, the application of jet mill is more and more popular. The ultramicro pulverizer is composed of a silo, a mechanical pulverizer, an induced draft fan, a cyclone, a vibrating screen, a liquid nitrogen tank, etc. The cryogenic pulverizer system uses liquid nitrogen as the cold source. After the crushed materials are cooled to become brittle and easy to crush at low temperature, they enter the chamber of the mechanical pulverizer and rotate at high speed through the impeller. Under the combined action of repeated impact, collision, shearing, friction, etc. between materials and blades, toothed discs, materials and materials, Achieve crushing effect. The wearing parts of the ultra-fine crusher have low loss. All wearing parts are made of high-quality wear-resistant materials at home and abroad, with a long service life. A small number of easily worn parts are made of hard wear-resistant materials, which are small in size, light in weight and easy to replace accessories. After being filtered and dried, the compressed air of the air flow pulverizer is sprayed into the pulverizing chamber at high speed through Laval nozzle. At the intersection of multiple high-pressure air flows, the materials are crushed by repeated collision, friction and shearing. The crushed materials move to the classification area with the rising air flow under the action of the fan pumping force. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, The fine particles that meet the particle size requirements enter the cyclone separator and dust remover through the grading wheel for collection, and the coarse particles drop to the crushing area for further crushing. This paper introduces the closed crushing function of air flow crusher, hoping to provide you with some effective help

The main application of the pneumatic pulverizer mechanism determines its wide application range and the fineness of the finished product. Typical materials include: superhard diamond, silicon carbide, metal powder, etc. High purity requirements: ceramic color, medicine, biochemistry, etc. Low temperature requirements: medicine, PVC. It can be used as an inert gas protection device by converting ordinary air of the gas source into nitrogen, carbon dioxide and other inert gases. It is applicable to the crushing and grading of flammable, explosive and oxidizing materials. There are several types of jet mill: flat jet mill, fluidized bed flame mill, circulating pipe jet mill, jet mill and target jet mill. The main performance characteristics of the air flow mill: 1. The air flow mill includes a vertical grading device. The product size can be adjusted at D97≤ 8~150μ M, the particle shape is good and the particle size distribution is narrow. It can be used in series with multi-stage graders to produce products with multiple particle sizes at one time. 2. The pneumatic grinder is easy to disassemble and assemble, with smooth inner wall and no dead corner. The whole system is closed and broken, with less dust and noise, and the production process is clean and environment-friendly. III. The control system of the airflow crusher is easy to program and operate. The function of jet mill is introduced.
