Factors that Influence Hammer Crusher Service Life

The hammer crusher is commonly applied in the industry of the mines, chemical industry, metallurgy, building materials, electric power and so on, while the hammerhead as a the main equipment of wear parts, its good or bad and service life directly impact on the efficiency of the crusher.
During work, subject to the dual role of long-term repeated impact and the impact of the materials, the working face of the hammer will be destroyed, so that the surface shape changes, and therefore need frequent replacement.
Hongxing Mine Equipment Co., Ltd. engineers according to the use status of the hammer, analyses Factors that Influence Hammer Crusher Service Life:
 (1) hammer head structure design and product quality
Hammerhead structure design and geometry have a great impact on mechanical properties and the internal microstructure after heat treatment; especially the thickness of the large size of the hammer, the impact is more prominent. From analysis, failure modes of different materials hammerhead fracture caused by varying degrees of defects in the internal or surface. Due to the presence of defects, most of the hammer appears fracture phenomena during the initial period. Therefore, in the hammer production, we must develop a reasonable casting and heat treatment process.
2 the technical parameters of the hammer crusher
Hammer Crusher technical parameters also affect the service life of the hammer, among which, the power and speed of the rotor is prominent. They are not only related to the production capacity of the crusher, also related to the degree of hardening of the hammer impact. If the degree of hardening of the hammer impact is good, its life will be prolonged.
3 , degree of hardness of the material
The greater of materials block, the higher of toughness requirements. While the higher of the hardness of materials, the higher requirements on the hammerhead material hardness. The specific model of the crusher should be matched with the appropriate particle size, which will extend the service life of the hammer to a certain extent.
　(4) Inside gap adjustment
Internal clearance of the Hammer Crusher is mainly refers to the gap between the rotor body and the back plate and hammer. The size of these gaps will be related to the discharge port, near the security gate plot material. If the product material exists, the hammer would be serious fricted and wore. Therefore, during the using process, you must often adjust each part of the gap to put them in an appropriate range.
There are many factors influencing the life of Hammer crusher, the four points above are derived from years of hammer crusher production experience and customer feedback information, and more information, please asks for expert advice.
