The RO (Raw Ore) pilot plant is a compact crushing and screening system designed for sand and aggregate production. The block diagram below outlines the key components:
1. Primary Jaw Crusher (Feed size: ≤600mm; Output: 100–200mm)
2. Secondary Cone Crusher (Closed-side setting: 20–50mm; Capacity: 50–150 TPH)
3. Tertiary Impact Crusher (For shaping; Output: 0–10mm)
4. Vibrating Screen (Decks: 2–4; Mesh size: 3–30mm)
5. Sand Washer (Water consumption: 20–50m³/h)
| Equipment | Model | Power (kW) | Capacity (TPH) |
|---|---|---|---|
| Jaw Crusher | PE-400×600 | 30 | 15–60 |
| Cone Crusher | PYB-900 | 55 | 50–90 |
| Sand Washer | LX-1000 | 7.5 | 30–80 |
Q1: What’s the final product gradation?
A: Adjustable via screen mesh (e.g., 0–5mm for fine sand, 5–20mm for coarse aggregate).
Q2: How to reduce dust emission?
A: Use water spray systems or bag filters at transfer points.
A limestone processing project in Vietnam achieved 120 TPH output with this configuration, producing ASTM C33-compliant concrete sand and 10–20mm aggregates. Key metrics:
– Energy consumption: ≤1.8 kWh/ton
– Sand recovery rate: ≥95%
