What maintenance should be done for the longer lifespan of the crusher hammer head

The basic way to improve the lifespan of crusher hammers has become one of the highly used mechanical equipment in recent years. Hammer crushers are commonly used in industries such as metallurgy, mining, building materials, and power. As the main vulnerable part of the crusher, the hammer head should pay special attention to material selection. At present, the hammer head of the crusher is mainly made of high manganese steel, but its wear resistance is poor, its service life is short, and it needs to be replaced frequently, which not only wastes materials but also affects normal operation. Therefore, improving the service life of hammer heads is an urgent problem to be solved.
Crusher Hammer Head
The working principle of a hammer crusher and the failure analysis of the hammer head: The material falls into the crushing chamber from the feeding port and collides with the high-speed rotating hammer head, and the crushed material collides with the grate at a certain gap at high speed. Repeat crushing of materials with larger particle sizes, and fine materials that meet the requirements after crushing are discharged through the gap between the grate bars. Although the impact of materials can produce a certain degree of work hardening, the impact force is not sufficient to form a solid hardening layer on the working surface of the hammer head, resulting in insufficient wear resistance of the hammer head and ultimately leading to the failure of the hammer head in the early stages of operation. Therefore, increasing the hardness of the hammer head can improve its wear resistance, thereby reducing impact wear; Improving the toughness of materials helps to suppress the generation and propagation of cracks, reducing erosion wear. Therefore, selecting appropriate materials is the fundamental way to improve the lifespan of crusher hammers.
