Air jet mill is different from other mills. It is under the action of high-speed air, the material passes through the impact between the particles, the impact of the air on the material and the shear effect of the material and the impact, friction, and shear of the material and other parts to crush the material. .
The air jet crusher uses materials under the action of high-speed air to obtain huge kinetic energy, which causes high-speed collision and fierce friction between material particles in the crushing chamber, and at the same time, the high-speed air produces shearing effects on the materials, thereby achieving the purpose of crushing the materials. It can process raw materials into extremely fine powder (<10μm). The application of this technology covers almost all fine processing industries, such as chemical, plastic, mining, metal materials, etc., and holds a special position in many specific powder fields.
Since the advent of the air jet mill in the 1930s, through the efforts of many researchers, its structure has been continuously updated and its types have been increasing. There have been flat or disc air mills, circulating air mills, collision air mills, and Chemical bed jet mill, target jet mill, supersonic jet mill, etc.
The energy saving problem of jet mill needs urgent solution
However, the equipment manufacturing cost is high, the energy consumption is large, and the processing cost is also large. The single machine has a poor processing capacity and the output is less than 2t / h, which is not suitable for large-scale production. Falling, processing costs have increased dramatically.
The airflow grinder faces serious energy-saving problems, solves the energy-saving problem of the airflow grinder, and will greatly expand the application of the airflow grinder. Considering the current "energy saving and environmental protection" requirements put forward by the country, energy saving will be one of the main directions for the improvement of air jet mills.
