Airflow pulverizer can keep ultra-fine powder in the shape of original particles Umico Powder Machinery

There are two basic methods to obtain ultrafine powder, one is physical method. The second is chemical synthesis. The main equipment for preparing ultrafine powder by physical method is the pulverizer, classifier and collection equipment with different principles, such as air flow pulverizer, vibration mill, Raymond mill, ball mill, etc. Among these equipments, jet mill is the first way to prepare superfine powder by dry method

Airflow pulverizer uses a number of relatively arranged nozzles to form high-speed airflow, and then uses high-speed airflow to accelerate materials to hypersonic speed so that they collide with each other at the intersection of nozzles, so as to achieve the purpose of ultra-fine crushing. The crushed materials enter the classification room of the classifier with the rising air flow. Because the classification rotor rotates at a high speed, the particles are subjected to both the centrifugal force generated by the classification rotor and the centripetal force generated by the viscosity of the air flow. When the particles are subjected to the centrifugal force greater than the centripetal force, that is, the coarse particles above the classification diameter return to the grinding room to continue to impact and crush. The fine particles enter the cyclone separator and the collector with the air flow for collection, and the gas is discharged by the induced draft fan< Br/>The MQW jet mill was used to prepare superfine powders for more than ten kinds of materials, and the particle shape of these superfine powders was observed and analyzed by electronic scanning electron microscope. It was found that the jet mill can keep most of the powders in the shape of original particles, so that the inherent properties of the powders can be fully exerted< Br/>MQW fluidized bed jet mill is a replacement product of traditional fluidized bed jet mill, opposed jet jet mill, horizontal jet mill and other types of jet mill. The equipment is mainly composed of crushing host, high-precision turbine classifier, cyclone collector, bag filter, air compressor, etc; Full utilization of jet energy is the main feature of zui
