An impact crusher consists of a rotor, impact bars, and wear plates. The rotor is the main component of the crusher, and it rotates at high speed to generate the necessary impact force. The impact bars, which are attached to the rotor, are responsible for crushing the material. The wear plates, which are also attached to the rotor, protect it from wear and tear caused by the impact force.
Regardless of the type of impact crusher, there are several essential parts that play a crucial role in the crushing process. These parts include the following:
| Item | Description | Item | Description |
| 1 | Front Frame | 6 | Rotor |
| 2 | Front Impact Bar | 7 | Side Liners |
| 3 | Rotor Bearing | 8 | Rear Impact Bars |
| 4 | Lower Frame | 9 | Rear Breaker Plate Adjuster |
| 5 | Blow Bars | 10 | Front Breaker Plate Adjuster |
The rotor is the main shaft that rotates at high speed to generate the necessary impact force. The rotor is typically made of high-strength steel and is designed to withstand the significant forces generated during the crushing process. The rotor may also be designed with various configurations, such as a solid or segmented design, to achieve a specific crushing goal.
Impact bars are the main components of the impact crusher that come into contact with the material being crushed. They are typically made of high-strength steel and are designed to withstand the high impact forces generated during the crushing process. The impact bars are usually fixed to the rotor and come in various shapes, such as rectangular or wedge-shaped, to achieve the desired crushing effect.
Side plates are also attached to the rotor and are designed to protect it from wear and tear caused by the impact force. These plates are typically made of high-strength steel and are replaceable to ensure the longevity of the rotor.
Apron liners are also side plates that are located on the top of the crusher housing and are designed to protect the crusher from wear and tear caused by the material being crushed. These liners are typically made of high-strength steel and are replaceable to ensure the longevity of the crusher.
Blow bars are a type of impact bar that is used in HSI crushers. They are designed to strike the material being crushed and to deflect it into the crushing chamber. Blow bars are typically made of high-strength steel and are replaceable to ensure the longevity of the crusher.
