Tungsten Carbide Hammer

Tungsten carbide hammer is also known as crusher hammer, which uniformly distribute in the hammer crusher rotor shaft. And in the high-speed rotation, directly impact on the material until reaching final appropriate particle size. Tungsten carbide hammer has many advantages, such as:
1. Since the center of crusher hammer outward radial direction in the radius of gyration, the line speed of hammer increases and the impact to material increases correspondly, so the crushing effect improved;
2. By improving the hammer can effectively increase the amount of wear, thereby reducing the cost;
3. Reduce the particle size to improve the output;
4. Improve the grinding effect and the grinding efficiency.

Currently, several common hammer materials include forging hammer, high manganese steel hammer, high chrome hammer and tungsten carbide hammer. Forging hammer crusher is suitable for crushing pebbles, coal and limestone. Forging hammer crusher with high-quality steel train wheels (material 65Mn, impact resistance, toughness, wear resistance, and not easily broken) by forging machinery and metal forging blanks repeatedly deform to obtain certain mechanical properties, certain shape and size. After special quenching method to ensure the hammer working area to obtain high hardness, high wear resistance performance; high manganese steel hammer crusher has good toughness, good process and low price, and the main characteristic is that under the effect of large impact or contact stress, the surface layer will quickly harden. The work hardening exponent is 5-7 times than other materials and the wear resistance is greatly improved; by comparison, tungsten carbide hammer has higher hardness, flexural strength, hot hardness, toughness, thermal fatigue and low cost (its wear resistance is 20 times higher than high manganese steel hammer). It can effectively solve the problems that crack, sealing-off, chipping-off and shedding.
