What are the wearing parts of the impact crusher?

The wearing parts of the impact crusher mainly include plate hammer, impact plate (impact liner), liner (side guard), square steel, clamping block, main shaft, rotor, pulley, etc. The following is a detailed introduction:

Plate hammer：It is a key and vulnerable part of the impact crusher, responsible for crushing the material into smaller particles. Due to long-term wear and impact, the plate hammer is prone to cracks, wear and other problems, and needs to be checked and replaced regularly. The material of the plate hammer is usually high chromium alloy, which has high wear resistance and strong impact resistance.

Impact plate (impact liner): It is one of the core components of the impact crusher, mainly used to prevent the crushed object from damaging the machine itself. The impact plate will be subject to great impact force, so it is easy to wear and break, and needs to be replaced regularly. The impact plate has two forms: broken line and arc shape. The arc-shaped impact plate has a higher crushing effect.

Liner (side guard): As the main protective part of the crusher shell, it plays an important protective role for the shell. After the liner is worn and aged, its impact resistance decreases, which can easily cause the liner to be shot down, and also cause the crusher’s sealing performance to decrease and produce large dust, which needs to be replaced in time.

Square steel: It plays a role in preventing the material from being discharged from the front. Square steel is square and can be divided into two types: seamed and seamless. The pressure resistance of seamless square steel is much greater than that of seamed square tubes.
Clamping block: It has excellent characteristics such as stable chemical composition, reasonable heat treatment process, good wear resistance and high strength. Its automatic clamping mechanism adopts cylinder drive, connecting rod mechanism and linear guide rail to realize the sequential actions of clamping, feeding, clamping at the other end, releasing at the same time, and returning of the clamping block, and the action is accurate and reliable.
Spindle: It is the power transmission component of the impact crusher, responsible for transmitting the power of the motor to the rotor. Due to long-term operation and wear, the spindle is prone to breakage, deformation and other problems, and needs to be checked and replaced regularly.
Rotor: It is one of the core components of the impact crusher, responsible for driving the hammer head for crushing. Due to long-term operation and wear, the rotor is prone to cracks, deformation and other problems, and needs to be checked and replaced regularly. The rotor has three structural forms: integral, combined and welded.

Pulley: It is a component that connects the engine and the impact crusher. Its core function is to transmit power. After long-term use, the pulley will have problems such as wear, imbalance and perforation, which can easily cause serious accidents, so it must be checked and replaced regularly.
