Abstract

The invention discloses a cyclonic jet mill. The jet mill mainly comprises a grader installed on a crushing box; the crushing box is provided with a crushing cavity which is driven by a power unit and is rotatably installed in the crushing box; the crushing cavity comprises an inner column which has a crushing space, an outer column is hermetically installed at the periphery of the inner column, an air flow channel which communicates with a compressed air source is arranged between the inner column and the outer column, an air flow nozzle is provided on the sidewall of the inner column and communicates with the air flow channel and the crushing space. The cyclonic jet mill provided in the invention overcomes the technical problems of formation of a dead space where air flow cannot reach in the crushing space and insufficient crushing of materials, has a reasonable design and is widely applied in ultrafine crushing of raw mineral materials, chemical raw material, heat sensitive substances and the like.

Description

technical field [0001] The invention relates to a solid material pulverizing device, in particular to a cyclone airflow pulverizer for pulverizing solid materials. Background technique [0002] At present, there are several types of jet mills, including target type, collision type, flat type, circulating tube type, and fluidized bed type. smash. However, the biggest structural defect of these types of airflow mills is that the airflow nozzle and the crushing space are fixed, the material enters the crushing space from a fixed direction, and the airflow nozzle shoots into the supersonic airflow from a fixed direction. Due to the influence of material specific gravity, particle size, hardness and other factors, the material entering the crushing space cannot be crushed by the supersonic airflow in time, and it is easy to form a crushing dead angle, and some supersonic airflows have reactive operations, so these types of airflow pulverizers are common. The disadvantages of lo...
