Three-Stage Crushing: The METRO AdvantageGranite is renowned for its extreme hardness and abrasiveness, demanding a robust, multi-stage approach to achieve both high throughput and premium product quality. METRO Machinery's three-stage solution delivers exceptional results:
- Primary:PE750*1060 Jaw Crusher-Handles feed sizes up to 630 mm with deep crushing cavity and heavy-duty manganese jaw plates for maximum durability.
- Secondary:PYS1313 Symons Cone Crusher-Provides excellent reduction ratio and produces well-shaped intermediate material with proven Symons technology.
- Tertiary:PF1210 Impact Crusher-Delivers final shaping with superior cubical particle geometry-essential for high-grade concrete and asphalt mix designs.
The inclusion of both a Symons cone crusher and an impact crusher in the same plant offers the customer unparalleled flexibility.
