The hammer shaft is assembled on the rotor and hangs several hammers horizontally. During the operation of the crusher, it bears the mutual grinding between the hammer rings. It is also a wearing part of the crusher, and the quality of the hammer also seriously affects the crushing. The normal operation of the machine. According to the hardness of the hammer, we can provide you with the hammer shaft of the corresponding material to ensure the normal operation efficiency of the crusher.
Feature
The alloy structure cast steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloy elements on the basis of ordinary carbon steel.
Medium alloy steel
Feature
Nickel (Ni) and other alloy elements are added to 42CrMo, and it is used for the rotor shaft of large gyratory crushers, large cone crushers, and super-large impact crushers/vertical shaft crushers.
Process technology
According to the different elements added, with appropriate smelting and heat treatment process to obtain high strength, high toughness, high wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other related special properties.
Scope of application
It is suitable for producing the wear-resisting spare parts with good mechanical strength and good toughness that are required for various working conditions, and the main steel structure castings with the required dynamic load.

Standard wear-resistant material with excellent impact resistance and work hardening properties.
Enhanced wear resistance with embedded alloy bars for superior performance in high-abrasion conditions.
Advanced ceramic composite matrix reinforcement technology for extended service life.
Bimetal composite structure combining wear-resistant surface with tough core material.
Excellent wear resistance with good hardness retention at elevated temperatures.
Rebuilding and reinforcement using advanced hardfacing welding technology.
Customized according to your operating conditions
For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.
For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.
For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
We will fully understand your working conditions and recommend the most appropriate material selection. Provide drawings based on your machine models and spare parts dimensions.
