airflow mill

Product description/ Product description


airflow mill is also known as airflow crusher, Jet mill, air - flow super - micro crusher. With its unique working principle, airflow mill can process the super fine powder of all kinds of materials with high purity and low temperature. The grinding process has no temperature rise, no pollution and little wear. It is especially suitable for ultra-pure superfine crushing of heat sensitive, low melting point and high purity material. The use of inert gas for flammable and explosive materials can be used as the working material to realize the closed-circuit circulation.


1. The crushing efficiency is high, the processing capacity is large, the content of the ultrafine powder is 15-30% lower than the similar equipment, and the granularity treatment interval is large, which can adjust the fineness between 1-100.
2. The material collides with each other to crush and wear little, and the product has almost no iron pollution, which guarantees the purity and physical and chemical properties of the product.
3. Airflow mill+ high precision turbine classifier can be high purity, ultra-narrow machining ultrafine powder, small amount of wear, and wear resistance lining inside. The grain size distribution is narrow and not large, especially suitable for the ultra-fine grinding of high hardness and high purity materials.
4. In the process of crushing, the air temperature is reduced due to the rapid expansion of airflow, especially for the pulverization of heat sensitive, low melting point, sugar and volatile materials.
5. The control system adopts program control and high degree of automation, which can automatically monitor and adjust the feeding speed, automatic unloading, simple operation and low noise (no more than 85dBA)
6. It can be used in series with multi-stage classifier, and it can produce multiple granularity segments at a time.
7. The whole system is closed and crushed, no dust, low noise, and clean production process.
Working Principle

airflow mill,with cyclone separator ,pulse dust collector and  draft  fan ,consists of crushing . Compressed air after being dried is injected into crushing chamber quickly by the injection of valves. At connection points of many high-pressure air currents, feed materials are collided, rubbed and sheared repeatedly to powders. The crushed materials go into classifying chamber with uprising air flow, under the condition of lashing forces of draft  fan. Under strong centrifugal forces of high-speed rotating turbo wheels, coarse and fine materials are separated. Fine materials in line with size requirements go into cyclone separator and dusting filter through classifying wheels, while coarse materials fall down to crushing chamber to be crushed continuously
