hammer shaft


We can provide you with various brands of hammer shaft , also can customize and produce according to your working conditions

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.

Medium alloy steel

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.

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.
