Thyssenkrupp Jaw Crushers are used for Primary Crushing. The material is crushed by compressive & shear forces. Flywheels with high moment of Inertia are generating high crushing energy & compensate crusher peak loads. The main feature of Jaw Crusher is the enhanced kinematics of the swing jaw with a high stroke feed & discharge area which ensures very high throughput rates.



Main Frame

Fully fabricated with quality-tested weldable steel plates. Reinforced and ribbed to withstand heavy primary crushing loads. Complete frame is stress relieved for long life. Fully machined for accurate seating and alignment of all components.

Swing Jaw Assembly

The swing jaw is of robust construction, fully stress relieved and machined to provide a firm support for the jaw plate.

The jaw plates are of profiled construction and reversible for maximum wear life. The main shaft is forged alloy steel, hardened & tempered, and designed to withstand heavy primary crushing loads. Precision machined to close tolerances and fine finish, the large size main shaft offers fatigue resistance and long life. The swing jaw and main frame bearings are heavy-duty double-row roller bearings, precision assembled, grease lubricated, and fitted with foolproof labyrinth seals

against dust ingression. The bearing arrangements are designed for continuous duty applications.

Toggle and CSS Adjustment

The toggle system is designed to handle large crushing pressures. The toggle ends and toggle seats are specially prepared for smooth rocking and least friction under no lubrication environment. Manually operated hydraulic jack arrangement facilitates quick removal of toggle and closed side setting adjustment.
