Working Principle
- Material enters the crushing chamber through a guide chute.
- Crushing occurs between a fixed jaw plate and a moving jaw plate.
- The material is progressively reduced until it passes through the set gap.
- The gap can be adjusted precisely using a hand wheel and scale.
- Zero-point calibration ensures accurate and repeatable settings.
Material Options (Jaw Plates & Liners)
- Hardened steel
- Tungsten carbide
- Heavy metal-free steel
- Stainless steel
Optional / Additional Configurations
- Infeed hoppers (stainless steel or PU-coated).
- Custom motor configurations (phase, voltage, frequency).
- Different jaw plate and liner materials based on application.
Applications
