Portable rock crushers are versatile machines designed to process hard rocks, gravel, and recycled concrete into high-quality aggregates. Ideal for on-site crushing, these units eliminate transportation costs and reduce environmental impact.
A typical setup includes:
– Primary Jaw Crusher: Handles large feed sizes (e.g., 600x900mm opening, 50–200TPH capacity).
– Secondary Cone/Impact Crusher: Produces finer aggregates (0–40mm output).
– Vibrating Screen: Classifies materials into multiple grades (e.g., 3-deck, 15–30° adjustable angle).
– Conveyor System: Belt width 500–1200mm, speed 1.0–2.5m/s.
| Model | Feed Size (mm) | Capacity (TPH) | Power (kW) |
|---|---|---|---|
| PJ-600 | ≤500 | 50–120 | 75 |
| PC-200 | ≤250 | 80–200 | 132 |
| S3-1860 | – | Screening: 100–300 | 22 |
Q: What’s the lifespan of wear parts?
A: Jaw plates last ~500 hours; cone liners ~800 hours (varies by material hardness).
Q: Can it process wet clay?
A: Not recommended—pre-screening or drying is advised to avoid clogging.
Project: Highway construction in Texas, USA.
Solution: Deployed a PJ-600 portable crusher + S3-1860 screen to produce 0–5mm, 5–20mm, and 20–40mm aggregates. Achieved 180TPH output with <5% oversize material.
