The equipment can be operated under aseptic conditions, the production process is continuous, the production capacity is large, and the degree of self-control and automation is high. Realize joint operation, because when superheated high-pressure saturated steam is used for pulverization, the material can be pulverized and dried at the same time, and it can be used as a mixer. When the material is pulverized, a solution of the required concentration can be sprayed to cover the solid Fine particles to form a coating layer and surface modification. Therefore, jet mill can be combined with pulverizing appearance coating and surface modification.
The air jet crusher, cyclone separator, dust collector and induced draft fan form a complete set of crushing system. After filtering and drying, the compressed air is sprayed into the crushing cavity at high speed through the Laval nozzle. At the intersection of multiple high-pressure air streams, the material is repeatedly collided, rubbed, and sheared to smash. The crushed material rises under the action of the fan. The airflow moves to the classification zone, and the coarse and fine materials are separated by the strong centrifugal force generated by the high-speed rotating classification turbine. Fine particles that meet the particle size requirements enter the cyclone separator and dust collector through the classification wheel to collect the coarse particles. .
Jet mill is one of the most commonly used ultra-fine crushing equipment . It is widely used in ultra-fine crushing of non-metallic minerals and chemical raw materials. It has the following characteristics. The products have the same fineness, narrow particle size distribution, smooth particle surface, and particle shape. Regular, high purity, high activity and good dispersibility. The product is less polluted, because the air crusher pulverizes the material according to the principle of self-grinding of the material, and the grinding cavity has less pollution to the product, so it is particularly suitable for crushing materials such as pharmaceuticals that are not allowed to be contaminated by metals and other impurities. It is suitable for crushing low melting point and heat sensitive materials and biologically active products. Because the jet mill uses compressed air as the power, the adiabatic expansion of compressed gas at the nozzle will reduce the system temperature, so a large amount of heat will not be generated during the work.
