The hammer head of the crusher is an accessory of the crushing equipment. When working, the rotor drives the hammer head to run at a high speed, directly hitting the material, and finally crushing it into a suitable particle size. Hammer heads of different materials have great differences in performance and toughness, and the applicable materials are also different. The hammer head of the crusher is a vulnerable part, which is closely related to the crushing equipment. Therefore, the wear resistance of the hammer head is directly related to the working efficiency of the crushing equipment. So, what are the materials of the hammer head of the crusher?
1. High manganese steel hammer head
Currently common and widely used materials. It is made of high manganese steel and high manganese steel, combined with advanced casting and heat treatment processes to adapt to different working conditions of the hammer crusher, so that the hammer head of the crusher can play the best performance. The high manganese steel hammer head has good toughness, Low price and strong impact resistance. It is suitable for making wear-resistant spare parts that are subjected to high impact load materials for a long time, and is widely used in metallurgy, mining, building materials, railways, electric power, coal and other grinding equipment.
2. High chromium cast iron hammer head
It is made of high-hardness high-chromium cast iron, commonly used are Cr20 and Cr26. After heat treatment quenching + tempering, the structure transforms into martensite and hard carbide points, the hardness is as high as HRC59-62, and the hardness is very high. Therefore, high chromium cast iron has been widely used as a high wear-resistant material in mechanical and metallurgical equipment such as crushing, grinding, and material transportation.
3. High chrome composite hammer head
Composite casting technology is adopted, the hammer head is made of high chromium cast iron with good durability, and the hammer handle is made of tough carbon steel, which integrates toughness and durability, so that the hammer head has high hardness, while the hammer handle has high toughness, which can play a good role The respective advantages of the two materials overcome the disadvantages of a single material, and the product does not break, meeting the performance requirements of the crusher hammer head. It is suitable for crushing high hardness materials, such as quartz stone, basalt, etc. Compared with several other materials, the composite hammer head has a complicated process and a relatively high price.
4. Forging hammer head
The forged hammer head is suitable for crushing pebbles, coal gangue, limestone, etc. The hammer head of the forging crusher is made of high-quality train hub steel material 65Mn, which has good impact resistance, strong toughness, good wear resistance, and is not easy to break. The forging machine is used to forge the metal blank repeatedly to deform it to obtain certain mechanical properties. With a certain shape and size, after a special quenching heat treatment method, the working area of the hammer head can be guaranteed to have high hardness and high wear resistance. Forged hammer heads are favored by users because of their cheap price, economy and durability.
The hammer head is an important part of the crusher equipment. The material of the hammer head is different, and its properties and applicable materials are also different. High-quality hammer heads not only have a long service life, but also directly affect the working efficiency of the crusher. When choosing a crusher hammer, it should be decided according to the actual needs and crushed materials.
