The DLGS Roller Screen is a heavy-duty industrial screening solution engineered for high-capacity coarse grain screening from 400 to 3,000 t/h. As a proven Roller Screen Mining Equipment, it is widely applied in mining, quarrying, construction waste processing, slag treatment, and soil & stone separation. The machine effectively handles wet, viscous, and sticky materials including mud & stone mix, coal gangue, and construction waste — applications where conventional vibrating screens struggle with blockage. Acting as a reliable Mud Stone Separator Machine, the DLGS series removes soil and clay-laden material efficiently thanks to its high-wetting-performance roller design. Its variable-speed frequency conversion motor allows operators to adjust screening speed in real time to match incoming material conditions. Built from high-quality alloy steel sieve pieces, the Roller Screen delivers excellent wear resistance and extended service life, reducing downtime and maintenance costs for demanding operations.
Raw material feed → DLGS Roller Screen → oversize discharge (coarse fraction) → undersize discharge (fines/soil removed) → downstream crushing or conveying
The roller screen's flat or inclined installation option allows it to integrate seamlessly into existing crushing and screening circuits.
| Model | Max Feed Size (mm) | Feeding Capacity (t/h) |
|---|---|---|
| DLGS1510 | <800 | 400–600 |
| DLGS1810 | <800 | 500–900 |
| DLGS2410 | <1000 | 1000–1500 |
Q1: What materials can the DLGS Roller Screen handle? A: The DLGS is designed for coarse grain screening of soft to medium-hard materials, including mud & stone mix, coal gangue, construction waste, slag, soil & stone mix, and mining ore. As a versatile Coal Gangue Roller Screen, it performs reliably even with wet, clay-rich, and viscous feeds that would block conventional screens.
Q2: What is the maximum feeding capacity? A: The DLGS series covers 400–3,000 t/h depending on model. The DLGS3010 (3,000 mm chute width) delivers up to 3,000 t/h, making it suitable for large-scale mining and aggregate operations.
Q3: Can the screening speed be adjusted? A: Yes. The DLGS uses a frequency conversion motor control system, allowing the roller speed to be adjusted based on material flow rate and moisture content for optimized screening efficiency.
