Abstract:
     The invention provides a whirl airflow pulverizing method, in particular it is applicable for manufacturing pulverizing machinery. The key of said invention is to use a driving device to produce a transverse high-speed rotating airflow in the pulverizing cavity to make material implement a rotating acceleration to form a columnal material whirling flow, and in the material column some sub-whirls of material flow are formed, and between the adjacent sub-whirls and between the sub-whril and material whirling flow the material particles can be mutually-collided so as to attain the goal of self-pulverization. So the high-purity ultra-fine pulverizing processing of material can be obtained. The invented pulverizer is simple in structure, and can be used in the industries of chemical, metallurigcial engineering, mining, building material, medicine, light industry and food, etc..
