How Many Types of Hammer Crusher Heads? The Most Wearable?
Hammer Crusher Heads
The hammer head of the crusher is one of the core components of the hammer crusher. It is arranged on the hammer shaft of the crusher rotor and directly hits the materials when the hammer crusher is operating.
Forged hammers are suitable for crushing pebbles, coal gangue, limestone, etc. The forged hammer head is made of high-quality train wheel steel, material 65Mn, which has good impact resistance, strong toughness, good wear resistance, and is not easy to break. After a special quenching heat treatment method, it can ensure that the hammer head’s working area has high hardness and high wear resistance.
Forging can eliminate defects such as as-cast looseness during metal smelting and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings. Forged hammers are favored by users because of their low price, economy and durability.
alloyed high manganese steel hammer
The alloyed high manganese steel wear-resistant hammer has reliable quality, and its wear resistance is three times that of traditional high manganese steel. This crusher hammer is widely used in large limestone crushers for dry cement production lines.
The high manganese steel crusher has good toughness, good manufacturability and low price. Its main feature is that its work hardening index is seven times higher than other materials.
However, the hammer head of the high-manganese steel crusher has higher requirements for the overall performance of the crusher. If the physical impact is not enough, the surface cannot be quickly worked hardened, so that it will not be able to exert its due wear resistance.
Therefore, it is hoped that customers should choose according to the actual parameters of the equipment before use, and if necessary, the equipment can be modified to maximize the economic benefits.
high chromium alloy crusher hammer
High chromium alloy hammer head, that is, the hammer handle uses high manganese steel, and the hammer head working area uses high chromium alloy. The two are combined to make the hammer head have high hardness, and the hammer handle has high toughness, giving full play to both The advantages of the materials overcome the shortcomings of a single material and meet the performance requirements of the hammer.
The high-chromium alloy hammer is especially suitable for crushing high-hardness materials, such as quartz stone, basalt, etc. However, the traditional manufacturing process is complicated, the process requirements are stricter, and the price is higher.
The high chromium alloy crusher has high hardness and is a high-quality wear-resistant material. It has been widely used in fine crushers (third-generation sand making machines) and impact crushers with supporting hammer frames, but the high chromium alloy toughness Inferior, it is prone to breakage without the support of the hammer frame.
cemented carbide hammers
Compared with other materials, cemented carbide hammers have higher hardness, bending strength and impact, thermal fatigue resistance, good thermal hardness, and low cost. It solves the cracks, desoldering and collapse of high manganese materials. Problems such as mouth, falling blocks and so on.
The cemented carbide hammer has super high wear resistance, which is more than 20 times that of the high manganese steel hammer, and can basically be adapted to all crushing industries.
