Jaw crusher is one of the important equipment in the mineral processing industry. It is mainly used for coarse crushing and medium crushing of materials such as rocks, gravel and artificial sandTo better understand, please learn about the structure and operating principle of jaw crusher in this article.
1. Basic structure of jaw crusher
Jaw crusher is made up of many main parts. Each part performs a separate function in the crushing process:
- Frame : Is the main part, keeps other parts fixed and protected from dirt.
- Fixed Jaw : Is the non-moving part, fixed on the machine frame. Helps clamp the material tightly during the grinding process.
- Moving Jaw : This part moves back and forth to crush the material between the static and movable jaws.
- Eccentric Shaft :The movement of the movable jaw is controlled by the eccentric shaft, which helps to generate crushing force.
- Toggle Plate : Connection between the movable jaw and the eccentric shaft. Helps transmit force and adjust the distance between the two jaws.
- Pull Rod : Helps maintain the position of the jaw during operation.
- Liner Plate : Protects the inner surface of the grinding chamber from wear.

2. Working principle of jaw crusher
Jaw crusher works on the principle of stamping and pressing. When the motor operates, it transmits power via a belt to the eccentric shaft. The eccentric shaft rotates, causing the movable jaws to move back and forth, clamping the material between the two jaws. This process takes place as follows:
- Loading: Material is fed into the grinding chamber.
- Mill:The moving jaw moves towards the static jaw, putting pressure on the material, causing it to break apart.
- Discharge:When the moving jaw moves away, the crushed material will fall out through the discharge port.
3. Benefits and applications of jaw crusher
Jaw crusher is widely used in fields such as mineral processing, construction, production of construction materials, ... Brings many benefits to production processes like:
- High performance: Capable of handling large volumes of material in a short time.
- High durability: Machine parts are often made of wear-resistant materials, prolonging product life.
- Easy to maintain: Simple design makes maintenance and repair easier.
