Carbon nanotube (CNT) powders are among the most challenging bulk materials to handle in modern industrial processes. Due to their nanoscale dimensions, extremely low bulk density, high specific surface area, and strong tendency to agglomerate, conventional conveying methods often lead to bridging, clogging, dust explosion hazards, and product degradation. Our advanced pneumatic conveying solutions are specifically engineered to overcome these hurdles, ensuring safe, gentle, and highly efficient transport of carbon nanotube powders from storage silos to processing equipment, packaging lines, or reactor feed systems.

We understand that every carbon nanotube production facility has unique requirements. Whether you are manufacturing multi-walled carbon nanotubes, single-walled carbon nanotubes, or functionalized CNT powders, our team designs customized pneumatic conveying systems that match your precise material characteristics, throughput demands, layout constraints, and safety standards. Our solutions cover both dilute phase and dense phase conveying modes, with the flexibility to switch between vacuum and pressure configurations based on your process needs.

Dilute phase pneumatic conveying is suitable for short-distance transfers where high velocity is acceptable and the material is not overly fragile. However, for carbon nanotube powders, we typically recommend dense phase conveying at low velocity to minimize particle attrition, reduce dust generation, and prevent the collapse of the porous structure. Our dense phase systems use gentle air injection and pressure control to maintain a stable plug flow, ensuring the CNT powder retains its critical properties such as aspect ratio, surface chemistry, and dispersibility.

Each carbon nanotube powder conveying system we deliver begins with a thorough material test in our state-of-the-art laboratory. We analyze the powder's particle size distribution, moisture content, cohesion, angle of repose, and aeration characteristics. This data allows us to select the appropriate conveying line diameter, air velocity, solid loading ratio, and filtration equipment. We also simulate the entire conveying path using computational fluid dynamics (CFD) to predict pressure drops, pick-up velocity, and potential wear points, guaranteeing reliable performance in real-world conditions.

Safety is a top priority when handling carbon nanotube powders. These nanomaterials are respirable and may pose health risks if inhaled. Additionally, their high surface area and combustibility require strict explosion protection measures. Our conveying systems are designed with closed-loop operation, HEPA-grade dust collection, inert gas blanketing options, and anti-static grounding throughout. We can integrate oxygen level monitoring, pressure relief panels, and flame arrestors to fully comply with ATEX, NFPA, or other local regulations. The conveying line is constructed from food-grade or pharmaceutical-grade stainless steel with a mirror-polished interior to prevent material retention and ease cleaning.

Our pneumatic conveying solutions include a wide range of components tailored to carbon nanotube powders. We supply rotary airlock valves, venturi feeders, vacuum loaders, blow vessels, and specially designed nozzle assemblies that introduce the powder into the air stream without compaction. For fragile agglomerates, we offer a de-agglomeration unit that breaks down soft lumps using controlled air jets while preserving primary particle structure. On the receiving end, we install cyclones, bag filters, and cartridge filters with pulse-jet cleaning to achieve high collection efficiency and minimize product loss.

Automation plays an essential role in our carbon nanotube powder conveying systems. Our control panel features PLC-based logic with a touchscreen interface, allowing operators to monitor pressure, airflow, material level, and filter differential pressure in real time. The system can be programmed for multiple transfer routes, automatic purging cycles, and batch weighing with high accuracy. We also provide remote monitoring and diagnostics via industrial IoT connectivity, enabling proactive maintenance and reduced downtime.

In addition to equipment supply, we offer complete engineering services. From conceptual design and 3D modeling to fabrication, installation, and commissioning, our project team ensures every milestone is delivered on time. We provide an operation manual, maintenance schedule, and spare parts list. Our after-sales support includes calibration, training, and rapid response for troubleshooting. We also offer retrofitting services to upgrade existing pneumatic conveyors to handle carbon nanotube powders more safely and reliably.

Typical applications of our carbon nanotube powder conveying systems include transferring CNT powder from a reactor to a purification vessel, delivering exact doses to a masterbatch extruder, feeding CNT powder into a mixing unit for composite materials, and packaging CNT powder into drums or bags under an inert atmosphere. We have successfully installed systems for battery material manufacturers, polymer composite producers, and specialty chemical companies. Each project is customized to fit the unique facility layout, whether it requires a simple straight-line transfer or a complex multi-line distribution network with automated diverter valves.

Power consumption is another critical factor in pneumatic conveying. Our optimized system design reduces energy usage by minimizing conveying pressure and using variable speed drives on blowers and compressors. We also recover and recycle the conveying gas where possible, further lowering operational costs. The low-velocity dense phase mode not only protects the material but also reduces pipe wear and noise levels, creating a cleaner and more comfortable working environment.
