The best prospect of mining in mechanical development de blog de crusher

In working process, rock impact crusher strikes mineral ores relying on high-speed operation of the hammeruntil they are crushed to be required particle size. However, hammer of used rock crusher is easily worn, which is to a great extent caused by low abrasionresistance, thereby affecting productivity of impact equipment. So, how to improve abrasion resistance of rock impactcrusher hammer is of great importance.

In terms of the low abrasionresistance of impactor breaker hammer at work, there are two solutions for choice:

  • (1) Introduce new design or new material to replace the traditional hammermaterial, and redesign heat treatment process of mineral impact crusher.If traditional raw materials of hammer such as high-manganesesteel receives greater pressure at work, its work hardening phenomenon will bemore obvious, and the formation of hardened layer will be more complete, so weincrease hammer weight to consolidate its hardening effect and improve the wearability of hammer. Also, we can choose materials with better abrasionresistance to make the hammerhead of mineral impact crusher.
  • (2) Deal with materials before they entering impactor equipmentto increase working pressure of impactor equipment hammerhead. You cansuitably increase feeding grain size of materials into mineral impact crusher,for example, filter materials below a certain size with sieve, which makes impact equipment receive greater impact stress in initial period of crushingmaterials and form enough work hardening layers so that increase abrasionresistance.

In addition, we can also dry materials before entering mineral impact crusher to reduce the moisture it contains, which helps increase its hardness coefficient,increase work pressure on the hammer and contribute to form work-hardening layer.
