Air mill is widely used in chemical, mineral, metallurgical, abrasive, ceramic, refractory, medicine, pesticide, food, health products, new materials and other industries. The reason why people choose it as factory production equipment is that air mill really plays an irreplaceable role.
Working principle of air mill:
The qualified fine powder is brought into the turbine classifier at the upper part of the fluidized bed by the updraft, and the qualified materials are classified by the airflow crusher and then enter the cyclone collector (if products with several particle sizes are required, several vertical turbine classifiers can be added). The finer tailings are brought into the bag filter by air flow. After being filtered by the bag filter, the tailings enter the outlet at the lower part of the filter, and the pure air is evacuated.
Main parts of the machine: standard vertical turbine classifier, crushing and grading are completed synchronously and harmoniously. The speed of the powder concentrator can be adjusted by frequency conversion, and the product fineness can be adjusted arbitrarily. For example, if a processing process requires products with multiple particle sizes, two to four can be added on the basis of one classifier, so as to make the machine a two machine and five machines for crushing and grading.
Scope of application: the crushing mechanism of this machine determines its wide scope of application and high fineness of finished products. Typical materials include superhard diamond, silicon carbide, metal powder, etc Ceramic pigment, medicine, biochemistry, etc. High purity, low temperature of drugs and PVC. By changing the ordinary air in the gas source into inert gases such as nitrogen and carbon dioxide, the machine can be used as inert gas protection equipment and is suitable for crushing and grading treatment of flammable, explosive and oxide prone materials.
Application of air mill:
1. High hardness materials: silicon carbide, various corundum, boron carbide, alumina, zirconia, garnet, zircon sand, diamond, etc.
2. Non metallic minerals: Yingshi, graphite, kaolin, calcium carbonate, mica, barite, mullite, Maifan stone, wollastonite, talc powder, pyrophyllite, etc.
3. Chemical industry: aluminum hydroxide, silica gel, various dyes, epoxy resin, various additives, etc.
4. Food and medicine: pollen, hawthorn, pearl powder, Ganoderma lucidum, all kinds of vegetable powder, all kinds of Chinese herbal medicine, all kinds of health products, cosmetics, antibiotics, etc.
5. Metal materials: aluminum powder, magnesium powder, zinc powder, tin powder, copper powder, etc.
6. Other materials; Ceramic materials, refractory materials, electronic materials, magnetic materials, rare earth materials, phosphors, copy material powder, etc.
Characteristics of air mill:
1. Large output, low energy consumption and high classification efficiency.
2. Concentrated particle size: the machine adopts the original vertical impeller classification. Stable classification technology and special sealing measures effectively prevent the leakage of coarse particles, so that the product has no large particles, concentrated particle size and high classification accuracy.
3. Reasonable structure: products with 1-6 particle sizes can be produced at the same time according to user requirements.
4. Strong applicability: it can be combined with various mills (air mill, mechanical mill, ball mill, Raymond mill, vibration mill, etc.) Form closed circuit or open circuit joint operation.
5. High degree of automation.
