Abstract

The invention discloses a hammer head of a hammer type crusher. The hammer head comprises a hammer handle, wherein a hammer ring and a hammer end are respectively casted at two ends of the hammer handle; a cavity is formed in the hammer end; a circular through hole communicated with the cavity is formed in the top center line of the hammer end; two ball bodies are symmetrically arranged in the cavity; the two ball bodies are isolated by virtue of an elastic body. By adopting the hammer head of the hammer type crusher, the ball bodies in the cavity are separated from the hammer head body after materials are hammered by the hammer head, so that the weight of the hammer head is reduced, and the swinging inertia of the hammer head around a pin roll is lowered. In a swinging process of the hammer head, the inner wall of the cavity of the hammer end continuously collides with the ball bodies to consume the energy of the ball bodies, so that the hammer head enters a stable state as soon as possible. The hammer head of the hammer type crusher can be used for effectively solving the system stability problem, so that the crushing efficiency is improved. In addition, the hammer end is designed into a hollow structure, so that casting defects can be reduced, and therefore, the hammer head of the hammer type crusher is convenient to cast and capable of improving the thermal treatment performance.

Description

technical field [0001] The invention relates to a hammer head of a hammer crusher. Background technique [0002] The hammer crusher uses the rapidly rotating hammer head to impact and crush the material, and is suitable for crushing brittle, medium-hard, and low-water-content materials. Since the hammer head of the hammer crusher is hinged and suspended on the pin shaft of the rotor body, when the hammer head hits the material, the hammer head will fall backwards, thereby reducing the strong impact on the rotor main shaft and the hammer head pin shaft. If the impact force passes through the collision center of the hammer head, theoretically, the instantaneous impact of the hammer head on the pin shaft can be eliminated, thereby reducing the wear on the surface of the pin hole and the pin shaft, and improving the stress state of the rotor main shaft. One of the great advantages of the crusher. When a single hammer head hits the material at high speed, the hammer head will p...

AI Technical Summary

Problems solved by technology

The crushing efficiency is directly proportional to the rotor speed, reducing the rotor speed will affect the crushing efficiency of the crusher; the hammer head connecting hole and the pin shaft are all metal materials, it is difficult to change the friction coefficient

That is to say, both of these methods have negative impacts and are difficult to implement. At present, there is no ideal way to improve system stability.
