Activated carbon powder is widely used in water treatment, air purification, solvent recovery, and industrial desulfurization. Its fine, lightweight, and abrasive nature makes handling difficult. Traditional manual feeding and mechanical conveying often cause dust leakage, material loss, and contamination. Our pneumatic conveying solutions are engineered to transport activated carbon powder safely and efficiently, with complete containment from storage to process equipment.

The conveying process starts with a rotary valve, screw feeder, or vacuum hopper introducing the powder into a sealed pipeline. Compressed air or blower-generated gas lifts and carries the powder through the line. At the destination, a receiver or filter separator removes the powder from the conveying air. Systems can be arranged as positive pressure to push material to several destinations, or as vacuum to pull material from multiple sources to a central point.

For activated carbon powder, we provide both dilute phase and dense phase conveying. Dilute phase uses high air velocity to suspend the powder; it is economical for short and medium distances. Dense phase uses high pressure and low velocity to push the powder as a plug, reducing particle attrition and pipe wear. Vacuum conveying is ideal for unloading big bags and feeding process vessels without dust exposure. The right mode is selected according to particle size, moisture content, distance, and throughput.

A complete system includes a blower or compressor, air dryer, feed hopper, rotary airlock, pipeline, diverting valves, filter receiver, level sensors, and a programmable logic controller. The PLC controls the conveying sequence, air pressure, and filter cleaning automatically. Contact parts are made of stainless steel or abrasion-resistant materials to withstand carbon powder wear.

Our systems provide low energy consumption, minimal maintenance, and continuous operation. The enclosed line eliminates dust emissions and keeps the work area clean. Automatic batch conveying and refill cycles reduce labor cost and ensure accurate dosing. Filter receivers use reverse pulse jet cleaning for high separation efficiency. Explosion relief vents and static grounding connections are available for hazardous areas. The system can also be integrated with dust monitors and remote control.

Activated carbon powder can form combustible dust clouds under certain conditions, so every system is evaluated according to ATEX, NFPA, and GB standards. We install explosion-proof motors, grounding straps, pressure relief panels, and flame isolation valves where necessary. The conveying air is filtered and safely discharged. The system prevents accumulation in dead zones through proper slope design and purge cycles. Operators are protected from inhaling fine particles, and fire or explosion risk is minimized.

Every application is different. We customize conveying capacity, pipe diameter, and air source based on bulk density, particle size distribution, and process layout. For bag dumps, big bags, silos, or drum feeders, we provide compatible intake modules. We can design a single-line or multi-line network with automatic diverting valves. This solution is used in drinking water plants, decolorization, solvent recovery, flue gas treatment, and pharmaceutical purification.
