Detailed explanation of the working principle and internal structure of the hammer crusher

Hammer crusher is a common crushing equipment widely used in industries such as mining, building materials, and chemical engineering. It mainly uses a high-speed rotating hammer to impact and crush materials. This article will provide a detailed analysis of the working principle and internal structure of the hammer crusher.
1、 Working principle:
The hammer crusher mainly crushes materials into the required particle size through impact crushing. The working principle is as follows:
1. Feeding: The material enters the crushing chamber of the crusher through the feeding port.
2. Impact: The material is impacted by a high-speed rotating hammer in the crushing chamber. The hammer head rotates around the axis of the rotor and moves along the radius direction of the crushing chamber at a certain speed. When the material is impacted by the hammer, high-speed collision and crushing occur.
3. Impact plate function: During the impact process, the material collides with the rotor and the impact plate in the crushing chamber, changing the direction of movement. This repeated collision and crushing causes the material to gradually break into the required particle size.
4. Discharge: The crushed material is discharged from the crushing chamber through the discharge port, completing the crushing process.
2、 Internal structure:
The internal structure of a hammer crusher includes the main working components such as the rotor, hammer head, and impact plate.
1. Rotor: The rotor is the core component of a hammer crusher, usually composed of a main shaft, a main hammer shaft, and a hanging hammer. Several hammer heads are installed on the rotor to generate impact force through high-speed rotation. The rotor is usually made of high-strength alloy steel to withstand significant impact and wear.
2. Hammer head: The hammer head is a crushing component on the rotor that crushes materials through impact with the material. There are various types of hammer heads in terms of quantity and structure, including single head, double head, and multi head. Hammer heads are usually made of wear-resistant alloy materials to ensure their long service life.
3. Impact plate: The impact plate is located on the inner wall of the crushing chamber and in direct contact with the hammer head. Its main function is to accept the impact force of the material and change the direction of its movement, allowing the material to receive more impact and crushing. The impact plate is usually made of high-quality alloy steel, which has high wear resistance and impact resistance.
In addition to the main components mentioned above, the hammer crusher also includes motors, transmission devices, feed and discharge ports, etc. The motor drives the rotor to rotate at high speed, and the transmission device transmits the speed of the motor to the rotor. The inlet is used to introduce materials into the crushing chamber, and the outlet is used to discharge the crushed materials.
In short, hammer crushers use high-speed rotating hammers to crush materials through impact crushing. It has the advantages of simple and clear working principle, high crushing efficiency, etc. Understanding its working principle and internal structure helps to better understand and use the hammer crusher, improving its crushing effect and production efficiency.
