Working Principle and Structural Analysis of Hammer Crusher

Hammer crusher is a commonly used crushing equipment, widely used in industries such as mining, metallurgy, building materials, and chemical engineering. Its working principle is to use a high-speed rotating movable hammer to impact, impact, and crush materials, achieving the goal of breaking large pieces of material into small particles of the required size.
The main structure of a hammer crusher consists of a body, a hammer head, a rotating shaft, a sieve plate, and an electric motor.
Firstly, the body is the supporting part of the entire crusher, usually made of welded steel plates. It has strong compressive strength and can withstand the impact force of a hammer.
Secondly, the hammer head is the core component of the hammer crusher, which is made of high-strength alloy material and installed on the shaft. The number of hammer heads is generally 6-16, which can be adjusted according to different crushing requirements. When the motor drives the shaft to rotate at high speed, the hammer head also rotates and impacts the material under the action of inertial impact force.
The shaft is the part that connects the body and the hammer head, which carries the rotational motion of the hammer head and completes the entire crushing process through the drive of an electric motor. The material of the shaft is generally high-strength alloy steel to ensure its ability to withstand high-speed rotation and impact forces.
The sieve plate is located at the bottom of the crushing chamber and has multiple holes for controlling the crushing particle size of the material. After being impacted by the hammer, larger materials will fall through the holes in the sieve plate, while smaller materials will be discharged through the holes in the sieve plate.
Finally, the electric motor is a key component that provides crushing power. Driven by an electric motor, the shaft rotates at high speed, causing the hammer head to generate high-speed impact energy, thereby achieving the crushing of materials.
Overall, a hammer crusher uses a high-speed rotating hammer to impact, impact, and crush materials, ultimately crushing large blocks of material into small particles of the required size. Understanding its working principle and structure is crucial for the correct use and maintenance of hammer crushers.
