A well-designed stone crushing and sand-making production line is critical for efficient aggregate processing. HP (High Performance) guidelines emphasize optimal equipment selection, automation, and energy efficiency to maximize output while minimizing operational costs.
The standard HP production line includes:
1. Primary Jaw Crusher (e.g., Feed size: ≤1200mm, Capacity: 50-800TPH)
2. Secondary Cone Crusher (e.g., Closed-side setting: 6-38mm)
3. Tertiary Impact Crusher/VSI Sand Maker (e.g., Max. feed size: 50mm, Sand yield: 30-60%)
4. Vibrating Screens (e.g., Deck layers: 2-4, Screening efficiency: ≥90%)
| Equipment | Key Parameters |
|---|---|
| Jaw Crusher | Inlet: 1200×1500mm, Power: 160kW |
| Cone Crusher | Max feed: 235mm, Capacity: 150TPH |
| VSI Crusher | Rotor speed: 1700rpm, Moisture tolerance: ≤8% |
Modern HP plants feature:
– Multi-stage crushing with closed-circuit screening
– Computerized process control systems
– Dust suppression systems meeting ISO 14001 standards
– Mobile configurations for temporary sites
Q: What’s the typical lifespan of wear parts?
A: Jaw plates last 3-6 months; cone mantles 4-8 months depending on abrasiveness.
Q: How to reduce flakiness index?
A: Use cone crushers with interparticle crushing technology.
Location: Malaysia granite quarry
Solution: Three-stage crushing with VSI shaping
Output: 500TPH (300TPH aggregates + 200TPH M-sand)
