Alumina powder is a critical raw material in electrolytic aluminum production. A well-designed pneumatic conveying system ensures dust-free, efficient, and continuous transfer from storage silos to smelting cells. Our customized solutions account for material properties, conveying distance, plant layout, and production requirements.

Alumina powder is abrasive, hygroscopic, and easily fluidized. We evaluate particle size distribution, bulk density, and moisture content before selecting conveying velocity, air volume, and pipe diameter. Dense phase conveying moves the material at low speed in plugs, reducing pipe wear and particle degradation. Dilute phase conveying is suitable for shorter distances and lower tonnage. We recommend the optimal mode for each plant.

Each system includes storage silos with discharge aids, rotary airlocks or pressure vessels, blowers or compressed air supply, wear-resistant pipelines, dust collectors, and PLC controls. For electrolytic aluminum plants, we integrate air chutes, belt conveyors, and hoppers with existing smelting equipment. Components are selected for durability, energy efficiency, and easy maintenance. Optimized pipe layouts reduce pressure loss and material accumulation.

Every plant has a different scale and layout, so we customize the entire system. We provide design, equipment selection, fabrication, installation, and commissioning. Operation can be manual, semi-automatic, or fully automatic. We also include expansion capability for future production increases. Custom options include stainless steel or carbon steel piping, multiple discharge points, batch or continuous conveying, and remote monitoring.

Accurate dosing is critical for stable smelting. By controlling the feed device or vessel pressure, the system delivers a consistent alumina flow to each cell. This prevents overfeeding or shortages, maintains electrolyte temperature, and improves aluminum quality. Weighing devices and flow sensors provide real-time data for process optimization. With a well-tuned control system, the plant reduces raw material consumption and energy usage.

Closed conveying prevents dust leakage and protects workers from alumina dust. High-efficiency filters and pressure relief valves ensure safe operation. The enclosed pipeline prevents moisture contamination, preserving alumina quality and fluidity. Compared with mechanical handling, pneumatic conveying reduces product loss and keeps the environment clean.

Reliability is essential in aluminum smelting. Our systems are designed for simple maintenance, with easy access to valves, bends, and sealing elements. PLC diagnostics detect plugging, filter pressure drop, or air supply failure before downtime occurs. We provide documentation, training, and after-sales support. Spare parts packages and maintenance schedules ensure long service life.

With years of experience in bulk material handling, we deliver complete alumina powder pneumatic conveying solutions for the electrolytic aluminum industry. From single-line systems to multi-point feeding networks, every project is engineered for efficiency, safety, and durability.
