How to Prolong the Service Life of the Hammerhead of Hammer Crushers

As fast consumables, hammer crushers widely used in the industries of mining, metallurgy, chemical engineering, construction materials and electric power are the most popular crushing machines. Moreover, the hammerhead of the hammer crusher is the main component that is usually worn out, so the quality of the hammerhead has direct influence on the crushing efficiency of the crushers.

At present, most hammerheads of Chinese hammer crushers are made of high manganese steel with poor abrasion and wear resistance and short service life, so they need to be replaced frequently. When the hammerhead of the crusher is working, it is crashed by the materials. The working surface of the hammerhead will be damaged with the shape being changed.

Then what are the factors that influence the service life of the hammerhead?

1.The structure design and the product quality

The structure design and the shape of the hammerhead will affect the mechanical property and inner metallographic structure after being heat treated. Especially for those hammerheads with large thickness, the influence will be stronger. Therefore, in the process of producing hammerheads, we need reasonable casting and heating technology.

2.The parameters of hammer crushers

The technical parameters of the hammer crusher will also influence the service life of the hammerhead, mainly having affect on the power sum and rotate speed of the rotor. They not only have something to do with the production capacity of the crushers, but also influence the impacting hardness of the hammerhead.

3.The blackness and hardness of the crushed materials

When the material blocks are with high hardness, there will be higher level requirement for the hammerhead materials. And for different crushers, we should select proper feeding particle size so that to some extent, we can guarantee the working life of the hammerhead.
