[0027] Working principle: The cyclone impact mill is a solid material crushing equipment, which is usually used to crush various dry materials, such as chemical raw materials, food raw materials and pharmaceutical raw materials, into particles of the required size, so as to facilitate subsequent processing. During the crushing process of the existing crusher, it is impossible to adjust the size of the crushed material particles of the crusher, which makes it only suitable for fixed materials and has a small scope of application. In order to solve this problem, a crushing mechanism and a positioning mechanism are set to push the limit rod 15 to rotate it to the side away from the limit block 14, thereby releasing the fixation of the sealing door 8.

At this time, the spring 11 is pulled by centrifugal force to extend the card block 10 and contact one end of the inner side of the positioning hole 12, thereby preventing the filter screen 5 from falling off. The material moves toward the classification impeller 2 under the drive of the cyclone, and the material particles of the required size pass through the blades 3 and the filter screen 5, and are output by the feed pipe 7 on one side of the classification impeller 2. The large particles of material are retained by the classification impeller 2 on the inner side of the pulverizer body 1 for crushing, so that the function of adjusting the size of the material after crushing by the pulverizer by replacing the filter screen 5 solves the problem that the existing pulverizer cannot adjust the particle size of the material after crushing.
