Hammer Crusher Parts High Chrome Hammer Head Castings And Forgings
Hammer head
Crusher Hammer
Crusher hammer such as clinker 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.
The High Mn imbedding cemented carbide hammer(Inlaid Alloy Hammer / alloy hammer/hammer mill) product made by our company use the wear resistant bar made from higher content nano-sized tungsten carbide and titanium carbide. The Rockwell hardness of wear resistant bar is 80HRA~90HRA. We will make the hammer’s matrix with high Mn or super high Mn according to the complexity of hammer mill. We make sure of the 100% metallurgical bonding of the alloy steel material bar surface and matrix by the method of blowing argon at bottom of furnace, diversified qualitative change, diversified inoculation, and appropriate casting, smelting, heat treating.These processing measure increase the combination property of the High Mn imbedding cemented carbide products made by our company. This kind of alloy steel material hammer is widely used in hammer mill. We meet with great favor from our customers at home and abroad.
