Composite crushing machine hammer

Abstract

The invention discloses a hammer head of a compound crusher, which comprises a hammer handle and a hammer body arranged below the hammer handle. The hammer handle is arranged on the top of the hammer head. The hammer handle is provided with a mounting hole. It is connected to the crusher through the installation hole; the hammer body is set at the bottom of the hammer head, and the hammer body is fixedly connected with the hammer handle. cut settings. The composite crusher hammer head can increase the wear resistance of the hammer head, improve the service life of the hammer head, reduce the frequency of replacing the hammer head, and reduce the production cost.

Description

technical field [0001] The invention belongs to the technical field of crushing devices for mine crushers, and in particular relates to a compound crusher hammer head. Background technique [0002] Crusher is widely used in mining, metallurgy, electric power and other industries. It mainly uses the high-speed rotating hammer head to collide with the material to break the material. The hammer head is the key part and the part that is most prone to wear and tear. Therefore, the crusher The consumption of the hammerhead is huge. There are many types of crusher hammerheads on the market at present. The accurate definition of the hammerhead should be the hammerhead of the hammer crusher. The hammerhead is one of the core components of the hammer crusher. On the hammer shaft of the crusher rotor, the hammer head directly hits the material when the crusher is running at high speed, and finally crushes the material into a suitable particle size. [0003] Crusher hammers on the mark...

AI Technical Summary

Problems solved by technology

High manganese steel has good toughness, good workmanship and low price. Its main feature is that under the action of large impact or contact stress, the surface layer will quickly produce work hardening, but if the impact force is not enough or the contact stress is small, it cannot Work hardening occurs rapidly on the surface, and the wear resistance of high manganese steel cannot be fully exerted.

High chromium cast iron is a wear-resistant material with excellent wear resistance, but its toughness is low and it is prone to brittle fracture

Because the head of the hammer head is used frequently and wears quickly, the hammer handle is basically not worn. The hammer head is only made of high manganese steel. Good strength, poor toughness, easy to break during use, affecting use
