The airflow pulverizer, cyclone separator, dust collector and induced draft fan form a complete crushing system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure air flows, the material is repeatedly collided, rubbed, and sheared to be crushed. The crushed material rises under the force of the fan. The airflow moves to the classification area, and under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator and dust collector for collection through the classification wheel, and the coarse particles drop to the crushing area to continue crushing. .
Jet flow mill is one of the most commonly used ultra-fine grinding equipment. It is widely used in ultra-fine grinding of non-metallic minerals and chemical raw materials. It has the following characteristics: uniform product fineness and narrow particle size distribution. , The particle surface is smooth, the particle shape is regular, the purity is high, the activity is high, and the dispersion is good.
The product is less contaminated. Because the airflow crusher crushes materials based on the self-grinding principle of the materials, the crushing cavity causes less pollution to the products, so it is especially suitable for crushing materials such as pharmaceuticals that are not allowed to be contaminated by metal and other impurities. It is suitable for crushing low melting point and heat-sensitive materials and biologically active products. Because the airflow crusher is powered by compressed air, the adiabatic expansion of the compressed gas at the nozzle will reduce the system temperature, so a large amount of heat will not be generated during the working process. Can be operated under sterile conditions. The production process is continuous, the production capacity is large, and the degree of self-control and automation is high.
Realize joint operations. Because when superheated and high-pressure saturated steam is used for crushing, the material can be crushed and dried at the same time, and can be used as a mixer; while the material is being crushed, a solution of the required concentration can be sprayed into it to cover the solid fine particles. Formation of coating layer and surface modification, therefore, jet crushing can be combined with crushing surface coating and surface modification. ?
