The core component of a hammer crusher is the hammer, which is mounted on the hammer shaft of the rotor and strikes the material at high speed to achieve the desired particle size. It is widely used in industrial crushing fields such as mining, coal, etc. The material of the hammer needs to balance the wear resistance of the head and the toughness of the handle. Common types include forged hammers, high manganese steel hammers, high chromium alloy hammers, and hard alloy hammers. Materials brand such as ZGMN18CR2, ZGCR26 etc. Among them, high chromium alloy hammers combine high hardness and impact resistance through composite processes, significantly improving their service life compared to traditional materials.

Hammer is a critical impact component for impact crushers, responsible for delivering high-energy impacts to break down raw materials. Manufactured via integral forging + heat treatment process, our hammers feature a dense microstructure that eliminates internal defects, reducing breakage rate to <0.5% per 1000 hours of operation. This reliability makes them a preferred choice for quarries, mines, and recycling facilities seeking consistent crushing performance.
Optimized Weight Distribution: Balanced center of gravity design reduces crusher vibration by 30%, protecting the rotor and bearing system from premature failure.
Replaceable Head Design: Wear-resistant head can be replaced independently without changing the entire hammer, cutting maintenance cost by 40% compared to one-piece designs.
