How does it works?: Inquiry Now

How does jaw crusher works? The working principle of a jaw crusher is to apply pressure and shear force to the material through the relative movement between the movable jaw plate and the fixed jaw plate, thereby achieving material crushing. Its core component is the crushing chamber, which is composed of a fixed jaw plate and a movable jaw plate. The material is crushed by being squeezed, split, bent and broken in the crushing chamber.

Detailed description of working principle

The working process of a jaw crusher can be divided into the following stages:

(1) Motor drive

The motor transmits power to the eccentric shaft through a belt and a pulley to make it rotate.

(2) Eccentric shaft rotation

The rotation of the eccentric shaft drives the movable jaw plate to move up and down periodically. The movable jaw plate is connected to the eccentric shaft through a toggle plate, and the movement trajectory is curved.

(3) Jaw plate movement

When the movable jaw plate approaches the fixed jaw plate, the material is clamped between the two jaw plates and is crushed by being squeezed, split, bent and broken.

When the movable jaw plate moves away from the fixed jaw plate, the crushed material is discharged from the discharge port below the crushing chamber under the action of gravity.

(4) Cyclic operation

With the continuous operation of the motor, the movable jaw plate moves periodically, continuously crushing and discharging materials to achieve batch production.

Working characteristics of jaw crusher

Crushing method: flexural extrusion type, high crushing efficiency, the material in the crushing chamber is subjected to multiple forces (extrusion, splitting, bending).

Crushing chamber design: The crushing chamber is large at the top and small at the bottom, which is convenient for material entry and discharge.

Scope of application: Mainly used for coarse and medium crushing of materials with high compressive strength such as ores and rocks, with a wide range of feed particle sizes (125-1200mm) and an adjustable discharge port.
