Hammer crusher

Abstract

The invention discloses a hammer crusher comprising an enclosure, a main shaft, a hammer carrier and a hammer shaft, wherein a feed opening is formed in the enclosure; the main shaft is rotatablely arranged at the enclosure; the hammer carrier is arranged on the main shaft; the hammer shaft is arranged on the hammer carrier, wherein at least one hammer head is arranged on the hammer shaft, and the at least one hammer head is a material moving hammer head with axial material moving function. The hammer crusher provided by the invention is provided with at least one material moving hammer head with axial material moving function, which is used for compulsively moving crushed materials in a crushing cavity in the axial direction. Therefore, the crushing time of the materials is prolonged at one hand, and on the other hand, small granules can pass sieve holes easily, so that the yield is large and the power is low.

Description

technical field [0001] The invention belongs to the technical field of crushing equipment, and more specifically relates to a hammer crusher. Background technique [0002] Hammer crusher is a kind of crushing equipment with a long history of application and a wide range of applications. It is generally used in medium and fine crushing operations. The main industries used are thermal power plants, mines, chemicals, building materials, etc. Its structure and working principle are that after the crushed material is fed from the feeding port, it is crushed by the impact of the high-speed rotating hammer head. There is a sieve plate under the hammer crusher, and the material particles smaller than the sieve gap fall into the lower part to become a product. Particles larger than the sieve remain in the machine and continue to be crushed. [0003] 1. The particle size of the crushed products of the existing hammer crusher should not be too small, which results in a small crushing ...

AI Technical Summary

Problems solved by technology

[0003] 1. The particle size of the crushed products of the existing hammer crusher should not be too small, which results in a small crushing ratio. When a smaller product particle size is required, either the output will drop sharply, or a fine crusher needs to be equipped, which will cause complicated procedures. , must adopt multi-stage crushing section and equipment

[0004] 2. When the water or mud content in the material to be crushed is too high, the output of the hammer crusher will be lower, and the crushing cavity may even be blocked. Therefore, the size of the sieve hole in the crushing cavity must be increased, but this will result in coarse particle size.

[0005] 3. If the existing hammer crusher needs to crush products with smaller particle size, the power consumption will increase sharply
