Crushers

Jaw crushers

Jaw crushers are mainly used as primary crushers.  Their main purpose is to reduce rocks to smaller sizes for the next crushing stages.  Jaw crushers are a popular alternative to primary gyratory crushers ,since they can process large amounts of hard material efficiently. 

Applicable materials:

Mining, metallurgy, construction, highway, railroad, and water conservancy, etc.

Capacity: 3-200 t/h

Feed size: 120-1200 mm

Power:  5.5-280 kw

Weight:  0.8-122 tons

Description

Jaw crusher is used in primary crushing for stones and bulk materials. Because of its simple structure, solidity, reliable operation, easy maintenance and overhaul, and relatively low production and construction costs, it is still widely used in metallurgy, chemical industry, building materials, and electric power , transportation and other industrial sectors, used for coarse, medium and fine crushing of various ores and rocks with compressive strength of 147-245MPa.

Features

Adjustable Discharge Opening

The gap between the jaws can be adjusted to control the size of the crushed material. This allows for customization of the output size.

High Reduction Ratio

Jaw crushers are designed to provide a high reduction ratio, meaning they can crush large materials into smaller particles efficiently.

Strong and Durable Construction

Jaw crushers are built with a robust and sturdy design to handle heavy-duty applications and withstand the rigors of continuous operation.

Efficient Crushing Performance

The design of the crushing chamber and the kinematics of the movable jaw contribute to efficient crushing, resulting in high productivity.

Energy Efficiency

Jaw crushers are designed to optimize energy consumption. Advanced technologies, such as hydraulic systems and flywheel inertia, contribute to reducing power usage

Compact Design

Jaw crushers are available in various sizes and compact designs, making them suitable for both stationary and mobile applications.

Working Principle

Jaw crushers
The motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw plate closer to the fixed jaw plate. At the same time, the material is crushed or split to achieve the purpose of crushing; when the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring, and finally the crushed material is discharged from the lower opening of the crushing chamber.

FAQ

- Regularly lubricate bearings and moving parts. - Inspect jaw plates, bolts, and toggle seats for wear. - Replace worn-out manganese jaws promptly. - Avoid overloading and ensure proper feed distribution.
Modern jaw crushers include: - Emergency stop buttons. - Safety guards for rotating parts. - Hydraulic adjustment systems to minimize manual intervention. - Automatic overload protection to prevent damage.
Jaw plate lifespan varies based on material hardness and usage. Typically, manganese jaws last **6–24 months**. Reversible plates can extend service life by allowing rotation for even wear distribution.
Yes. Mobile jaw crushers combine a crushing unit with a feeder, conveyor, and chassis, enabling on-site crushing for construction, demolition, or mining projects. They offer flexibility and reduce transportation costs.
Capacity (TPH) depends on: - Feed material hardness and size. - Crusher dimensions (e.g., inlet width). - CSS (closed-side setting) adjustment. - Operational speed and stroke.
