Abstract

The invention provides a supersonic jet milling system, which relates to the technical field of powder material milling. A main body comprises an air compressor, an air storage tank, an air freeze dryer, a supersonic jet mill, a cyclone separator, a dust remover and a draught fan, wherein the right end of the air compressor is connected with the air storage tank; the right end of the air storage tank is connected with the air freeze dryer; the right end of the air freeze dryer is connected with the supersonic jet mill; the right end of the supersonic jet mill is connected with the cyclone separator; the right end of the cyclone separator is connected with the dust remover; and the right end of the dust remover is connected with the draught fan. The supersonic jet milling system is reasonable in structural design, has the advantages of low noise and no vibration and is suitable for a dry type ultrafine milling process; since the impact velocity is high, particles 1-10 micrometers in size are very easy to obtain, and coarse particles in a product can be continuously and circularly milled, so the product with uniform particles and a small particle size distribution range can be obtained.

Description

Technical field: [0001] The invention relates to the technical field of pulverizing powder materials, in particular to a supersonic jet pulverizing system. Background technique: [0002] Jet milling equipment is widely used in chemical industry, minerals, metallurgy, abrasives, ceramics, refractory materials, medicine, pesticides, food, health products, new materials and other industries. The crushing mechanism determines its wide application range and high fineness of finished products, which can meet High-purity requirements, such as: ceramic pigments, medicine, biochemistry, etc.; can meet the requirements of low temperature, such as: medicine, PVC. By changing the ordinary air in the gas source part to inert gases such as nitrogen and carbon dioxide, it can be transformed into inert gas protection equipment, which is suitable for crushing and classifying processing of flammable, explosive, and oxidizable materials. Jet milling equipment usually forms a complete crushing...
