high manganese steel cliner crusher hammer head with build-up welding
Crusher hammer such as cliner crusher hammer and raw material hammer is one of the core parts of hammer crusher.Our hammer crusher parts:crusher hammer use refining, vacuum casting,directional solid and etc technicals to increase the grain refinement and make the hammers performance achieve the best performance. Hammer hasrdness is the most essential factor in determining hammer life so the hammer head must be extremely hard and resistant to wear. Our company uses a specical method of heat treating that make the hammer hardness and wear resistance reach the best state of cooperation, thus greatly improve hammer’s service life time. According to the material, our crusher hammer can be dividede into: high manganese hammer, high chrome hammer, bimetal composited hammer. The bimetal composite hammer, our national patent product, is called “Hard Stone Killer” by many clients. Our crusher hammer generally can save users 1/3 equipment investment, saving 1/2 the power consumption, save a lot of maintenance costs.
The alloy steel material that be crushed by hammer crusher is a tremendous difference. The crusher has different forms and hammers. In the condition of crush hard and tough material such as iron raw, Our high Cr bimetal hammer could bear the cutting from the material but easy be come off or break for the hammer’s toughness property is not good. Though the toughness of supper Mn steel is higher but the wear resistant property is not enough. So hammer and blow bar made from high Mn imbedding cemented carbide is the best choice.
