Detailed explanation of the main components of the hammer crusher

Hammer crusher is a common crushing equipment widely used in industries such as mining, metallurgy, and building materials. The following will provide a detailed introduction to the main components and functions of a hammer crusher.

1、 Crushing chamber

The crushing chamber is the main working area of a hammer crusher, consisting of a feed inlet, a crushing zone, and a discharge outlet. The material enters the crushing chamber from the feeding port and is crushed into small pieces by the impact of the hammer and the friction of the sieve plate, and then discharged from the discharging port.

2、 Rotor

The rotor is the core component of a hammer crusher, consisting of a main shaft, a disc, and a hammer shaft. The rotor rotates at high speed under the drive of the driving device, generating centrifugal force that causes the hammer to strike and break the material. The design and manufacturing quality of the rotor directly affect the performance and service life of the crusher.

3、 Hammer head

Hammer head is a crushing tool installed on the rotor, directly involved in the material crushing process. Hammer heads are generally made of wear-resistant materials such as high manganese steel, which have good toughness and wear resistance. During use, the hammer head will constantly wear out and needs to be replaced regularly to ensure the crushing effect.

4、 Sieve plate

The sieve plate is located at the bottom of the crushing chamber and plays a role in screening materials. The crushed material is discharged through the sieve holes of the sieve plate, while materials larger than the sieve hole size continue to remain in the crushing chamber for secondary crushing. The design and adjustment of sieve plates have a significant impact on the discharge particle size and production efficiency of crushers.

5、 Drive device

The driving device is the power source of the hammer crusher, generally composed of components such as an electric motor, a reducer, and a coupling. The driving device transmits torque and speed to make the rotor rotate at high speed inside the crushing chamber, thereby achieving the crushing effect on the material.

In summary, the main components of a hammer crusher include the crushing chamber, rotor, hammer head, sieve plate, and driving device. These components perform their respective duties during the crushing process, working together to complete the crushing task of the material. Understanding the structure and function of these components can help us better use and maintain the hammer crusher, improve its work efficiency and service life.
