Jaw Crusher Machine For Sale

Jaw crushers are undoubtedly familiar to all. Whether in the sand and gravel aggregate, mineral processing, or building materials sectors, jaw crushers effectively reduce large blocks of ore into smaller aggregates. They offer distinct advantages including straightforward operation, simple construction, ease of maintenance, and substantial processing capacity. Consequently, the jaw crusher has become an essential piece of equipment in crushing plants. It is suitable for processing various ores and stones with compressive strengths ranging from 147 to 245 MPa, including river pebbles, granite, boulders, and construction waste. It is a common sight in stone crushing plants and open-pit mining operations.

Main Components of the Jaw Crusher

Jaw Plates: The jaw plates constitute the core components of the jaw crusher. They comprise: the movable jaw plate and the fixed jaw plate. Material undergoes continuous compression within the crushing chamber formed between the movable and fixed jaw plates, thereby achieving fragmentation. Movable Jaw Plate: Connected to the connecting rod and eccentric shaft, it is capable of vertical oscillation. Fixed Jaw Plate: Mounted on the front wall of the frame, its position remains stationary.

Eccentric shaft

The eccentric shaft serves as the main drive shaft of the jaw crusher, functioning as a crank mechanism. Driven by an electric motor, it induces the reciprocating motion of the movable jaw plate. Subjected to immense bending and torsional forces, the eccentric shaft is typically fabricated from high-strength alloy steel renowned for its exceptional wear resistance.

Elbow plate

The elbow plate transmits power transmission forces. and also supports the lower end of the movable jaw for oscillation. It also functions as the jaw crusher’s safety device. When encountering difficult-to-crush materials in the feed, the toggle plate fractures first, protecting the crusher’s valuable components from damage.

Flywheel

Mounted at both ends of the eccentric shaft, the flywheel possesses substantial mass and inertia. It is commonly used to store energy and balance the rotational motion of the eccentric shaft, ensuring smoother operation of the crusher during operation.

Frame

The frame constitutes the supporting structure of the jaw crusher, categorised as either monobloc or modular. It serves to secure and support all components. The frame must exhibit high rigidity and stability to withstand the intense impact forces generated during crushing operations.

Working Principle of the Jaw Crusher

The jaw crusher is driven by an electric motor via a belt and pulley system. This drives the eccentric shaft, causing the movable jaw plate to move continuously up and down. During the upward movement of the movable jaw plate, the angle between the toggle and the movable jaw increases. This propels the movable jaw plate towards the fixed jaw plate. Simultaneously, the material is crushed and split, achieving the crushing objective. When the movable jaw plate descends, the angle between the toggle and the movable jaw decreases. under the action of tie rods and springs, the movable jaw plate moves away from the fixed jaw plate. Material is discharged from the bottom outlet of the crushing chamber. As the motor continues to rotate, the movable jaw plate cycles through crushing and discharging operations, enabling large-scale production.

Advantages and Features of Jaw Crushers

High crushing efficiency, convenient operation

Deep crushing chamber with no dead zones. Dual wedge block discharge adjustment mechanism. Adjustable via mechanical or hydraulic methods. Offers greater convenience and efficiency compared to traditional shim plate discharge adjustment.

Standardised Design, Reduced Technical Risk

The jaw crusher has undergone technological upgrades and enhancements. Core designs, including the crushing principle of the moving and fixed jaw plates and the optimised V-shaped crushing chamber, adhere to international standards. This ensures stable equipment operation and efficient material processing.

Modular production for lower overall costs

The movable jaw plate, fixed jaw plate, and eccentric shaft employ universal specifications. Standardised manufacturing processes reduce production costs. Compared to high-priced equipment from major brands, small and medium-sized manufacturers offer high-quality wear plates at significantly lower costs, providing greater affordability.
