Causes of fracture and failure of crusher hammer and improvement plan

Analysis of causes of fracture and failure of hammer

1. Material problem: If the material of the hammer does not meet the use requirements, such as insufficient hardness and toughness, it is easy to break under the impact force.
2. Design defects: The shape and size design of the hammer are unreasonable, which may lead to stress concentration and cause fracture.
3. Manufacturing process: The manufacturing process of the hammer is not standardized, such as improper heat treatment, which will lead to uneven internal structure of the hammer and reduced strength.
4. Improper use: Overload operation of the crusher or mismatch between the material properties and the equipment will increase the load of the hammer and cause fracture.
5. Maintenance: If the wear of the hammer is not replaced or adjusted in time, it will also cause the hammer to break.

Improvement plan

1. Optimize material selection: Select high wear-resistant and high-toughness alloy materials to improve the comprehensive performance of the hammer.
2. Improve the design: optimize the shape and size design of the hammer head to avoid stress concentration and increase the service life of the hammer head.
3. Standardize the manufacturing process: strictly implement the manufacturing standards of the hammer head, ensure that the heat treatment and other processes meet the requirements, and ensure the quality of the hammer head.
4. Reasonable use: select the appropriate crusher model and hammer head according to the nature of the crushed material to avoid overload operation.
5. Strengthen maintenance: regularly check the wear of the hammer head, replace or adjust it in time to reduce the risk of breakage caused by wear.

The fracture failure of the crusher hammer head is a problem affected by multiple factors. By optimizing the material, improving the design, standardizing the manufacturing process, reasonable use and strengthening maintenance, the fracture failure of the hammer head can be effectively reduced, and the stability and economic benefits of the crusher can be improved.
