How does impact crusher work?
Impact crusher (impact crusher) is an efficient crushing equipment, and its working principle is based on the impact crushing of materials by high-speed rotating rotors. The following is the working principle and characteristics of impact crusher:
1. Basic working principle
The impact crusher impacts and crushes the material through the plate hammer on the rotor. The specific process is as follows:
Feeding: The material enters the crushing chamber from the feed port.
Impact crushing: The plate hammer on the high-speed rotating rotor produces high-speed impact on the material to crush it preliminarily.
Rebound and re-crushing: The crushed material is thrown to the impact plate along the tangential direction and crushed again under the action of the impact plate.
Circular crushing: The material repeatedly impacts between the plate hammer and the impact plate until it reaches the required particle size and is finally discharged from the discharge port.
2. Core components and functions
Rotor: The rotor is equipped with a plate hammer, which is the main component of crushing. Its high-speed rotation provides impact force for the material.
Plate hammer: It directly contacts the material and completes the crushing through high-speed impact.
Impact plate: Located at the other end of the crushing chamber, it is used to rebound the crushed material and improve the crushing efficiency.
Crushing chamber: The main space for material crushing, its shape and size affect the crushing effect.
3.Adjustment method
The discharge particle size of the impact crusher can be adjusted in the following ways:
Rotor speed: Increase or decrease the rotor speed to change the degree of material crushing.
Gap between the impact plate and the plate hammer: The gap is adjusted through a mechanical or hydraulic system to control the discharge particle size.
Summary
The impact crusher uses a high-speed rotating rotor and plate hammer to impact and crush the material, and combines the action of the impact plate to achieve multiple crushing, which has the advantages of high efficiency, energy saving, and high crushing ratio. Users can adjust equipment parameters according to specific needs to meet different production requirements. This equipment is widely used in building materials, mining, chemical industry and other fields.
