When processing placer alluvial ore, sticky clay and mixed‑size gravel always bring screening troubles. Ordinary vibrating screens are easy to get blocked by wet mud. A trommel screen (rotary drum screen) becomes the preferred washing‑screening unit for small‑to‑medium mining operations.
The core component is an inclined rotating cylindrical drum fitted with wear‑resistant screen mesh. Driven by reduction motor, the drum rotates slowly. Raw ore enters from feed hopper. High‑pressure water jets inside wash clay and mud away. Fine mineral particles pass through screen holes, flow down to next‑stage gravity separation equipment such as sluice box, shaking table or centrifugal concentrator. Large‑size rock waste moves along drum slope and discharges as tailings.
✅ Anti‑clogging performance: Rotation tumbling self‑cleans mesh, works well for wet, clay‑bearing ore which blocks vibrating screens easily. ✅ Flexible capacity: From small portable unit to large stationary model, capacity covers 1‑80 tons per hour. ✅ Modular configuration: Can match feed hopper, high‑pressure water system, sluice box, wheel‑mobile chassis. ✅ Low maintenance: Simple mechanical structure, wear‑resistant manganese steel screen panel for long service life. ✅ Reduce downstream load: Removes large waste rock in early stage, cuts energy consumption for subsequent grinding and beneficiation.
