The hammer head of crusher is an accessory of crushing equipment. When working, the rotor drives the hammer head to run at high speed and directly hits the material, and finally breaks into appropriate particle size. Different materials of hammer head, toughness difference is large, suitable for different materials. Crusher hammerhead is a wearing part, which is closely related to crushing equipment. Therefore, the wear resistance of hammer head is directly related to the working efficiency of crushing equipment. So, what are the materials of crusher hammer head?
1, high manganese steel hammer head
Now common, widely used material. The use of high manganese steel production, combined with casting and heat treatment process production, to adapt to the different working conditions of hammer crusher service conditions, so that the crusher hammerhead to play a good performance, high manganese steel hammer good toughness, low price, impact resistance. It is suitable for making wear-resistant spare parts which can withstand the wear of materials with high impact load for a long time. It is widely used in metallurgy, mining, building materials, railway, electric power, coal and other wear breaking equipment.
2, high chromium cast iron hammer head
High hardness of high chromium cast iron material production, commonly used are Cr20, Cr26. After heat treatment quenching + tempering, the structure changes into martensite and hard carbide particles, hardness up to HRC59-62, high performance. Therefore, high chromium cast iron has been used in crushing, grinding, material handling and other mechanical and metallurgical equipment as a high wear resistance material.
3, high chromium composite hammer head
Adopted the compound casting technology, hammer head adopt high chromium cast iron, with good sex of hammer handle the toughness of the carbon steel, toughness and wear resistance for an organic whole, make the hammer head with high hardness, and the hammer handle has high toughness, play to their advantages of two materials and overcome the shortcoming of a single material, products do not break again, both satisfy the crusher hammers using performance requirements. Suitable for crushing high hardness materials, such as quartz stone, basalt, etc. Compared with other materials, composite hammer head technology is complex and the price is relatively high.
4, forging hammer head
Forging hammer is suitable for breaking cobblestone, coal gangue, limestone and so on. Forging crusher hammers using high quality train wheel steel material 65 mn, good impact resistance, strong toughness, good wear resistance, not easily broken, used in forging machinery for metal blank forging repeatedly, make its produce deformation in order to obtain certain mechanical properties, a certain shape and size, after special hardening heat treatment method, ensure the hammer head work area with high hardness, high wear resistance performance. Forging hammer head is favored by the majority of users because of its low price, economic and durable characteristics.
Hammer is an important part of crusher equipment, hammer material is different, its toughness and suitable materials are also different. High quality hammer not only has a long service life, but also directly affects the working efficiency of the crusher. In the selection of crusher hammer, or according to the actual demand and crushing materials to decide.
