Key Components & Working Principle

1. Fixed Jaw Plate – Stationary crushing surface attached to the crusher frame.
2. Moving Jaw Plate – Swings in an elliptical motion due to the eccentric shaft.
3. Eccentric Shaft – Rotates via motor and belt drive, creating the oscillating motion.
4. Toggle Plate – Acts as a safety mechanism and helps transmit crushing force.
5. Pitman – Connects the moving jaw to the eccentric shaft.
6. Spring Return System – Ensures the jaw returns after crushing.

How It Works

• The motor drives the eccentric shaft via belts/pulleys.
• As the shaft rotates, the pitman moves elliptically, forcing the moving jaw against the fixed jaw.
• Material fed into the crushing chamber is compressed and broken into smaller pieces.
• The crushed material exits through the discharge opening at the bottom.

Advantages of Single Toggle Design

✔ Simpler construction than double toggle
✔ Lower maintenance
✔ Higher capacity for given size
✔ Efficient crushing motion
