The term “250tph 300tph medium hard rock” typically refers to a crushing plant designed to process 250 to 300 tons per hour (tph) of medium-hard rock material. This type of setup is commonly used in aggregate production, mining, or construction projects.
Key Components for a 250-300 TPH Medium-Hard Rock Crushing Plant
1. Primary Crusher
– Jaw Crusher (e.g., C125, C140) or Gyratory Crusher for initial size reduction.
– Handles large feed size (up to ~1,000mm) and reduces it to ~150-200mm.
2. Secondary Crusher
– Cone Crusher (e.g., HP300, CS430) for further reduction to ~20-50mm.
– Suitable for medium-hard rocks like granite, basalt, or limestone.
3. Tertiary Crusher (Optional)
– Fine cone crushers (HP400, CS440) or impact crushers for shaping and final product sizing (~5-20mm).
4. Screening & Conveying
– Vibrating screens (3-deck screens) to separate different aggregate sizes.
– Belt conveyors to transport material between stages.
5. Supporting Equipment
– Feed hopper with vibrating feeder.
– Dust suppression system.
– Control panel & automation (optional).
Example Rock Types Considered “Medium Hard”
– Granite (~6-7 Mohs hardness)
– Basalt (~6 Mohs)
– Limestone (~3-4 Mohs but abrasive)
Estimated Power Requirements
– Primary + Secondary crushing: ~300-400 kW total power consumption.
Final Product Applications
– Road base aggregates (~20-40mm)
– Concrete aggregates (~10-20mm)
– Railway ballast (~30-50mm)
