Cohesive target type water fluid jet grind

Abstract

The invention relates to a solid material crushing device, in particular to a cohesion target type water-jet mill which is characterized by comprising a material grading part, a material crushing part and a stand, wherein the material grading part comprises a central feed pipe, an overflow suspension assorting cylinder, an overflow groove, an annular water uniform distributor, and a water shock conical vibration sieve; the upper part of the overflow suspension assorting cylinder is welded with the overflow groove which is provided with a discharge hole; the lower end of the overflow suspension assorting cylinder is connected with the upper end of a cylinder body of a crushing part of the material crushing part through a flange; a feed hole of the central feed pipe is higher than the discharge hole of the overflow groove; the material crushing part comprises a material guide cone, the cylinder body of the crushing part, an annular nozzle holder, a nozzle, a cohesion target body, a conical water injector, a grading hopper and a separating grate sieve; and the cylinder body of the crushing part is fixedly connected with the stand. The cohesion target type water-jet mill has the characteristics of high utilization rate of energy and good effects of cleavage and crushing.

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...

AI Technical Summary

Problems solved by technology

[0013] The above two post-mixing jet mills ⑤ and ⑥ are relatively simple in structure, easy to operate, capable of continuous operation, and large in processing capacity, but there are also problems of insufficient mixing of material particles and high-speed water jets to varying degrees, low energy efficiency and Classification and particle size control and other issues
