Hammer disk structure for single-segment hammer crusher

Abstract

The invention provides a hammer disk structure for a single-segment hammer crusher, which can be used for effectively prolonging the overall service life and stability of a hammer disk and lowering the manufacturing cost. The hammer disk structure for the single-segment crusher comprises a hammer shaft which forms a rotating pair with a hammer shaft hole on the hammer disk, and a hammer head connected to the hammer shaft, wherein a lining is arranged in hammer shaft hole; and the hammer shaft is rotationally arranged in the lining.

Description

technical field [0001] The technology relates to a hammer-disc structure of a single-segment hammer crusher. Background technique [0002] In the existing PSJ2425 single-stage hammer crusher, in use, due to the large feed particle size, the hammer shaft is subject to torsion and impact force, so the whole hammer plate needs to be made of high-priced alloy material, and the hammer shaft hole of the hammer plate is used. In the process, serious wear and deformation often occur, resulting in the oval shape of the hammer shaft hole, and the concentricity of a row of hammer shaft holes seriously exceeds the requirements, and the hammer shaft is subjected to uneven force when it is impacted, and fracture occurs. As a result, the hammer shaft is replaced frequently, and the life of the hammer disc is too short, which seriously affects the normal use of the crusher and increases the use and maintenance costs of the crusher. SUMMARY OF THE INVENTION [0003] The purpose of the pre...

Problems solved by technology

[0002] The existing PSJ2425 single-stage hammer crusher is in use, because the feed particle size is large, the hammer shaft is subject to torsion and impact force, so the overall hammer plate needs to be made of high-priced alloy material, and the hammer shaft hole of the hammer plate is in use Severe wear and deformation often occur during the process, resulting in an elliptical hammer shaft hole, and the concentricity of a row of hammer shaft holes seriously exceeds the requirements, and the hammer shaft is unevenly stressed when impacted and breaks

As a result, the hammer shaft is frequently replaced, and the life of the hammer plate is too short, which seriously affects the normal use of the crusher and increases the use and maintenance costs of the crusher.
