Modern stone crusher machinery forms the backbone of aggregate processing plants, transforming raw materials into high-quality sand and gravel for construction. Key equipment includes jaw crushers, cone crushers, impact crushers, and vibrating screens, each playing a critical role in crushing efficiency and product gradation.
1. Primary Jaw Crusher: Handles large-sized rocks (up to 1,500mm feed size) with outputs adjustable from 50–300mm. Models like PE-600×900 offer 60–160t/h capacity.
2. Secondary Cone Crusher: Fine-crushing for 5–40mm aggregates. HP300 cone crushers deliver 90–250t/h with hydraulic adjustment.
3. Tertiary Impact Crusher: Produces cubic-shaped sand (0–5mm). VSI6X series achieves 50–500t/h with rock-on-rock crushing.
4. Vibrating Screen: Multi-layer decks (e.g., 3YK3070) separate aggregates into precise sizes at 50–800t/h.
| Equipment | Model | Capacity (t/h) | Output Size (mm) |
|---|---|---|---|
| Jaw Crusher | PE-750×1060 | 110–320 | 80–140 |
| Cone Crusher | HPT300 | 120–310 | 5–40 |
| VSI Crusher | S8-1145 | 200–450 | 0–5 (sand) |
Q1: How to reduce dust in crushing plants?
A: Use water spray systems + enclosed conveyors + bag filters.
Q2: Lifespan of crusher wear parts?
A: Manganese jaws last ~200k tons; VSI rotors require replacement every 800h in abrasive conditions.
