What materials are used for crusher hammer?

August 26, 2024

The materials of crusher plate hammers mainly include forged hammer heads, bimetal composite hammer heads, high manganese steel hammer heads, high chromium cast iron hammer heads and high chromium alloy hammer heads. ‌

‌Forged hammer head‌ is suitable for crushing cobblestones, gangue, limestone, etc. It is made of high-quality train hub steel material 65Mn, which has the characteristics of good impact resistance, strong toughness, good wear resistance, etc., and is not easy to break. The metal blank is repeatedly forged by a forging machine to deform it to obtain certain mechanical properties, a certain shape and size, and then undergoes a special quenching heat treatment method to ensure that the working area of the hammer head obtains high hardness and high wear resistance.

‌Bimetal composite hammer‌ is a material widely used in daily applications. It has longer service life than high manganese series materials. It is especially suitable for large crusher hammers, plate hammers and large ball mill linings. It is used in harsh industrial and mining conditions. The work effect is remarkable in the environment.

‌High manganese steel hammer‌ contains more than 10% manganese and has excellent wear resistance and impact resistance. When the surface is subjected to sufficient impact, a hardened layer will be formed. As the hardened layer wears, a new hardened layer will be formed, which is suitable for making wear-resistant spare parts that can withstand high impact load material wear for a long time.

‌High chromium cast iron hammer head‌After appropriate alloying and related process measures, the hardness of the entire section can reach more than 58hrc, ensuring hardness and high wear resistance during the wear process.

‌High chromium alloy hammer head‌ has high hardness and is a high-quality wear-resistant material. After heat treatment, the hardness can reach more than 58hrc. The matrix is high-hardness martensite, and the structure contains a large amount of high-hardness carbide M7C3, which is considered Good wear-resistant material for crusher hammer heads.

The choice of these materials depends on the characteristics of the material, the design of the crusher and the requirements of the working environment. Each material has its specific advantages, so in practical applications, it is very important to choose the right material according to specific conditions‌.
