Abstract

The invention relates to a solid material crushing device, in particular to a superfine cavitation target type water-jet mill which is characterized by comprising a hopper, a cavity of the mill, a granularity regulating plate, a jet mixing accelerating part, an impact regulating target body and a stand, wherein the hopper is fixed on the upper end of the cavity of the mill and is communicated with an injection cavity of the cavity of the mill; the bottom of the cavity of the mill is fixed on the stand; a diffusion mixing pipe of the jet mixing accelerating part is fixed in a cavity of a diffusion mixing pipe positioning seat in the cavity of the mill; a nozzle mouth of a cavitation nozzle is positioned in an input port of a diffusion mixing pore channel; the impact regulating target body is positioned on the left of an output port of the diffusion mixing pipe of the jet mixing accelerating part; the granularity regulating plate is arranged on the position of an output end of a gradually varied channel with an arc section and a grading discharge hole in the cavity of the mill; and the grading discharge hole of the cavity of the mill is communicated with the output end of the gradually varied channel. The superfine cavitation target type water-jet mill has the characteristics of high utilization rate of crushing energy and easy regulation of granularity.

Description

technical field [0001] The invention belongs to the field of powder engineering, and in particular relates to a solid material crushing device. Background technique [0002] Water jet technology is a new technology gradually developed in the 1960s. From the initial water jet mining, it gradually developed into the fields of water jet cleaning and cutting. By the mid-1980s, the University of Missouri-Rilla The Rock Mechanics and Blasting Technology Research Center first used high-pressure water jets to conduct wood, waste paper pulping, municipal solid waste treatment, and coal and mineral crushing tests, thus starting the research on high-pressure water jet crushing technology, and it has increasingly attracted people. attention. The new technology of high-pressure water jet crushing is attracting more and more people's attention. Some people believe that high-pressure water jet crushing, ultrasonic crushing and thermal crushing technology may be an innovative technology in...
