Working principle and technical parameters of jaw crusher

The working principle of a jaw crusher is based on the reciprocating movement of the movable jaw that compresses and crushes the materials against the fixed jaw. The materials are fed into the crusher through the feeding hopper and are crushed between the fixed jaw and the movable jaw. The moving jaw moves back and forth periodically, exerting a compressive force on the material, which is crushed and discharged from the discharge port at the bottom of the crushing chamber.

The technical parameters of a jaw crusher include:

1. Feed size: The maximum size of the material that the crusher can accept.

2. Capacity: The amount of material that the crusher can process per unit time, typically measured in tons per hour.

3. Discharge size: The size of the crushed material after being discharged from the crusher.

4. Power: The power rating of the motor that drives the crusher.

5. Eccentric shaft speed: The speed at which the eccentric shaft rotates, which affects the crushing force and efficiency of the crusher.

6. Weight: The weight of the crusher, which affects its portability and installation requirements.

7. Dimensions: The physical dimensions of the crusher, which determines how much space it requires and how it should be installed.

In summary, a jaw crusher works by compressing materials against a fixed jaw with a reciprocating motion of the movable jaw. The technical parameters of a jaw crusher include feed size, capacity, discharge size, power, eccentric shaft speed, weight, and dimensions. Understanding these parameters is important for selecting the appropriate jaw crusher for a specific application.
