A trommel wash plant is a critical component in sand and aggregate production lines, designed to separate materials by size and remove contaminants. This system integrates screening, washing, and dewatering functions to produce high-quality construction-grade aggregates.
1. Trommel Screen: Rotating drum with adjustable mesh (typically 5–50mm) for primary classification.
2. Log Washer: Aggressively scrubs clay-bound materials (capacity: 50–400 TPH).
3. Sand Screw: Dewaters fine particles (output: 20–150 TPH; moisture content <15%).
4. Cyclone Unit: Removes silt and ultra-fines (<75µm).
| Component | Key Parameter |
|---|---|
| Trommel Drum | Diameter: 1.8–3.6m; Length: 4–9m |
| Water Consumption | 30–80m³/hour |
| Power Requirement | 45–200 kW |
| Throughput | 50–500 TPH |
A 250 TPH plant achieved 95% material recovery using:
– Tier-4 diesel/electric dual-power trommel
– Two-stage sand screws for ≤12% moisture content
Q1: How to reduce pebble loss?
A: Optimize trommel slope (4–7°) and spray bar pressure (2–3 bar).
Q2: Ideal feed size?
A: ≤100mm for efficient washing; pre-crushing recommended for larger feed.
Q3: Maintenance focus?
A: Monthly bearing lubrication and screen panel torque checks (±10% spec).
