The technical scheme adopted in the utility model is as follows:

A new type of wet pulverizer, including a base, a bearing seat is installed on the base and a motor is installed through the support, the bearing seat is equipped with a main shaft through a bearing, and the main shaft is driven by the motor;

The upper end of the main shaft is equipped with a moving knife, and the upper end of the pump body containing the moving knife is equipped with an end cover, and the fixed knife corresponding to the moving knife is fixedly installed under the end cover; the moving knife includes the ring gear of the moving knife and the impeller , the fixed knife includes a fixed knife ring gear, the impeller is placed in the center of the fixed knife gear ring, tooth grooves are evenly distributed on the moving knife gear ring and the fixed knife gear ring, and the periphery of the moving knife gear ring is provided with a screen ; The end cover is provided with a feed port, the feed port is equipped with a feed hopper, and the pump body outside the movable knife is provided with a discharge port and a slag discharge port.

As a further improvement of the above technical solution:

Carbide blocks are inlaid on the movable knife.

The mesh of the sieve is 300 mesh.

The range of linear velocity when the moving knife rotates is: 50-80m/s.

The beneficial effects of the utility model are as follows:

The utility model has the advantages of simple structure, high working reliability, high crushing efficiency and good crushing effect. The stainless steel inlaid carbide cutter head makes the cutter more wear-resistant and solves the problem of rapid cutter wear when crushing hard materials; innovatively introduces the slag discharge function, through single-stage crushing and double outlet discharge, to achieve material, The slag separation realizes the continuous production of materials with a large amount of impurities; the unique skeleton stainless steel screen structure is used to ensure that the crushed materials are discharged at a certain fineness, the smallest can reach more than 300 mesh, and the product quality is guaranteed; Through the ultra-high crushing line speed, the crushing effect is guaranteed.
