In industrial environments where precision, safety, and environmental compliance are non-negotiable—such as mining, cement production, or chemical processing—the right material handling solution can make or break operational efficiency. For powders, granules, and small lumps like coal, cement clinker, or mineral ores, a heavy-duty screw conveyor isn’t just an option—it’s a necessity.
Unlike belt conveyors that struggle with fine particles and dust generation, spiral conveyors offer sealed, controlled movement of bulk materials over long distances—up to 150 meters—and vertical lifts of up to 20 meters. Their design adapts seamlessly to different particle sizes: fine powders (e.g., fly ash) require tighter sealing and slower rotation speeds; larger granules (like crushed limestone) need robust helical blades and higher torque motors.
| Parameter | Typical Range | Impact on Application |
|---|---|---|
| Max Horizontal Distance | ≤ 150 m | Enables integration into large-scale plants without intermediate transfer points |
| Vertical Lift Capacity | Up to 20 m | Ideal for stacking systems, silos, or multi-level processing units |
| Screw Rotation Speed | 15–60 RPM | Adjustable for material sensitivity—minimizes degradation of fragile products |
“Our plant reduced dust emissions by 78% after switching to fully enclosed screw conveyors. Maintenance costs dropped by 40%, and OSHA compliance became effortless.” — Plant Manager, Mining Co. (Australia)
The true value of modern screw conveyors lies not only in their mechanical performance but also in how they protect people, equipment, and the environment. Sealed systems prevent airborne particulates from escaping—a critical factor for industries under strict EPA or EU regulations. This leads directly to lower maintenance cycles, fewer shutdowns, and improved worker safety.
Take the TQ-SC series used in a major cement facility in Saudi Arabia. With daily throughput exceeding 120 tons of raw meal, this model maintained consistent output across 18 months of continuous operation—even during sandstorm seasons when external dust levels spiked. In another case, a pharmaceutical manufacturer in Germany adopted the same technology for transporting active ingredients, achieving zero cross-contamination due to its hermetic seal design.
