Jet Mills Type Selection Tips

　　With the development of material refinement and high purification, the domestic crushing technology is also constantly improving. As the most fine crushing equipment in dry crushing, jet mills have many types. So how to choose the type?

　　It is necessary to know the structure and principle of the main jet mills on the market first. According to the structure, the types are mainly include (the controlled particle size is arranged from coarse to fine): spiral jet mill, fluidized bed vertical jet mill, fluidized bed horizontal jet mill, superheated steam jet mill.

　　After the equipment classification is clarified, it is necessary to clearly knowthe applicable industries of each type.

　　Spiral jet mills are mainly used in medicine, food, health care products and some other fields, because its characteristics of simple structure and easy to disassembly and clearing meets the requirements of clean production.

　　Fluidized bed vertical jet mills are applicable for high-yield users, such as chemical, mineral, abrasive, refractory and other common industries.

　　The fluidized bed horizontal jet mill, compared with the vertical type,has a horizontally installed grading impeller, which can really achieve the purpose of controlling fine particles. It is suitable for users require refinementin various industries.

　　Steam jet mills, a type that replaces air compressors, saves energy and reduces consumption, and promotes flow. Applicable: fly ash, slag, barium sulfate, titanium dioxide, talc, silica, aerogel and other special industries.

　　Secondly, it is necessary to distinguish the fineness that can be achieved by each type of jet mill.

　　Spiral jet mill, 200 mesh-5µm. With the increase of particle size, the production capacity gradually decreases.

　　2. Fluidized bed vertical jet mill, 200 mesh-3µm. With the increase of particle size, the production capacity gradually decreases.

　　3. Fluidized bed horizontal jet mill, 200 mesh -1µm. With the increase of particle size, the production capacity gradually decreases.

　　4. Steam jet mill, 200 mesh -0.5µm. With the increase of particle size, the production capacity gradually decreases.

　　However, generally if the final product is below 500 mesh, it is recommended to use a mechanical pulverizer, mainly considering that its production cost is acceptable. The energy consumption of the jet millis relatively high, but the industries with high added value can be ignored.

　　Furthermore, the selection should be based on the characteristics of the raw materials, such as the viscosity, toughness, fluidity, ductility, moisture absorption, easy oxidation, easy combustion and explosion of the materials and other special characteristics which will have an impact on the selection, and it is necessary to communicate with professional technical personnel in detailand take their advice.

　　Finally, the air flow crusher, especially the fluidized bed type, has a variety of classification impeller subdivisions. It will also have an impact on particle size, output, particle shape, etc. it is better to consult and communicate with manufacturing enterprises when making choices. I wish you all good equipment and good service. Jointly promote the development of national crushing industry.
