Solutions To Extend Hammers Service Life

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

Because of its simple structure, high crushing ratio, and less energy consumption, hammer crusher is widely used in many industries and get very popular among investors. But the hammers in hammer crusher are very easy to damage. This is also the main problem customers pay special attention to. So in this article, we focus on solutions to extend the service life of hammers in hammer crusher.

Solutions To Extend Hammers Service Life

Choose Suitable Material

Choosing suitable materials to make hammers is the basic solution to extend their service life. In the crushing process, hammers bear various levels of impact force and cutting force, so hammers should have high toughness and high hardness. Improve the hardness of hammers can improve their toughness and reduce the impact damage. Improve the toughness of hammers can effectively restrain the produce and expand of cracks and reduce the erosion damage. But toughness and hardness is a pair of contradiction, in the actual choosing of materials to make hammers, manufacturers should fully understand the working condition and wear mechanism, choosing suitable materials.

Proper Design Of Hammers

In order to extend the service life of hammers, while designing and choosing the structure of hammers, manufacturers should pay attention to the following factors:

  • Under the premise of meeting the impact strength, manufacturers should adopt hammers with holes on the both sides. Once damaged, we can change side and use it continuously.
  • To improve the wear resistance of hammers, manufacturers can weld a thin layer of hard metal on the working face of hammer or adopt assembled hammers. The working part of hammers can adopt materials with high hardness and other parts can adopt materials with high toughness, making the hammers wear resistance and impact resistance.
  • The hammers should be easy to repair. When the hammers wear to a certain degree, if not badly damaged, we can adopt bead weld to repair them.

Strengthen The Management And Maintenance

Properly operation and regularly maintenance is the basic method to keep the hammer crusher stay in good condition and to extend the service life of hammers. If the operation and maintenance of hammer crusher is improper, it will not only cause faults in hammer crusher, but also reduce the service life of hammers. In the operation and maintenance of hammer crusher, we should pay attention to the following factors:

  • Customers should properly control the feeding size of raw materials according to the specifications of hammer crusher. The feeding size of raw materials should be under allowed range.
  • Choosing suitable feeding equipment, making sure the raw materials are fed into hammer crusher evenly and continuously.
  • While changing new hammer, it’s better to weigh it, making sure the weight is the same with other hammers.
  • While stop the hammer crusher, operators should check the gaps between hammer and grid section, grid section and grid section. If there is any need, operators should adjust them.
