    The working principle of the air flow crusher is to use the strong turbulent flow field formed when the high-speed air flow is ejected, so that the solid particles in it will be deformed and broken in the self impact or impact with the impact plate and the wall The powder is added into the feeding nozzle by electromagnetic vibration feeder, and then it is injected into the grinding chamber under the action of feeding compressed air The high-speed air flow from the feeding nozzle forms supersonic flow, which causes collision, shearing and collision with the wall of the grinding chamber to achieve the purpose of pulverizing into powder In the process of high-speed movement and pulverizing of the material flow, particles of different fineness will be in the rotating air flow Different centrifugal forces are generated, and the powder particles with qualified fineness are taken to the discharge pipe by the exhaust airflow because the centripetal airflow force is greater than its centrifugal force, and the finished products are collected by the cloth bag, while the larger particles are thrown to the periphery because the centrifugal force is greater than the centripetal airflow force, and the powder refining process continues with the high-speed movement of the material flow Performance characteristics: 1 There is a vertical classification device inside, which can adjust the product particle size The particle size is good, and the distribution is relatively narrow, the product fineness is uniform, the particle surface is smooth, the shape is regular, the purity is high, the activity is large, and the dispersion is good 2 It is suitable for crushing low melting point and heat sensitive materials and biological active products Because the air flow crusher is powered by compressed air, the adiabatic expansion of compressed gas at the nozzle will reduce the system temperature, so a lot of heat will not be generated in the working process 3 It can be used in series with multi-stage classifier, so that multiple particle size segments can be formed at the same time 4 The equipment is easy to disassemble and clean There is no dead corner on the inner wall It can be cleaned thoroughly and operated in sterile state 5 Closed operation, low operation noise, can reduce the generation of dust, not only environmental protection, product pollution is less 6 Continuous production process, large production capacity, high degree of automatic control and automation, simple operation of control system, safe and reliable operation of equipment 7 Joint operation can be realized When the superheated high-pressure saturated steam is used for crushing, the materials can be crushed and dried at the same time, and can be used as a mixer; when the materials are crushed, they can be sprayed with the solution of the required concentration, so as to cover the solid fine particles to form the coating layer and carry out the surface modification Therefore, the air flow crushing can be combined with the crushing surface coating and surface modification What are the advantages of the traditional Chinese medicine cells smashed by the ultra-fine pulverizer?
