Key Features of Jaw Crushers
1. Crushing Mechanism:
– Uses two vertical jaws (one fixed, one moving) to compress and crush materials.
– The movable jaw exerts force on the rock by pressing it against the stationary jaw.

2. Materials Processed:
– Hard rocks (granite, basalt)
– Concrete & demolition waste
– Recycled asphalt

3. Applications in Construction:
– Primary crushing in quarries
– Demolition debris recycling
– Road & building construction

4. Advantages:
– High efficiency & durability
– Simple maintenance
– Adjustable output size

Types of Jaw Crushers
1. Single Toggle Jaw Crusher – Movable jaw swings in an arc; efficient but higher wear.
2. Double Toggle Jaw Crusher – More complex but reduces wear and offers better crushing action.
3. Mobile Jaw Crushers – Mounted on tracks/wheels for portability (e.g., Metso Lokotrack, Sandvik QJ series).
