CMC powder, or carboxymethyl cellulose sodium, is a fine, hygroscopic, cohesive water-soluble polymer used in food, pharmaceuticals, daily chemicals, oil drilling, textile, papermaking, and construction. Due to low bulk density and strong bridging tendency, reliable transfer requires an enclosed pneumatic conveying system. Pneumatic transport protects material quality, prevents dust leakage, and provides flexible routing throughout the plant.

Our CMC powder pneumatic conveying solution is customized to your material, distance, capacity, and layout. We supply complete systems including silos, hoppers, rotary feeders, screw conveyors, blowers, vacuum receivers, bag filters, pipelines, diverter valves, sensors, and PLC controls. Every component is selected to ensure stable feeding, accurate batching, low energy use, and easy maintenance.

We provide both dilute phase and dense phase conveying. Dilute phase suspends powder in high-velocity air, ideal for short or medium distances and moderate throughput. Dense phase moves CMC in low-velocity plugs, reducing degradation, wear, and energy consumption. Our engineers select the most efficient mode based on your material and process requirements.

Positive pressure and vacuum conveying are available. Positive pressure systems push material through pipes and can feed multiple points via diverter valves. Vacuum conveying draws powder from bag dump stations, silos, or mixers into a receiver, ideal for dust-free loading and multiple pickup points. We recommend the best configuration for your plant layout and production flow.

Because CMC is highly hygroscopic, conveying air must be dry and filtered. We add desiccant dryers, moisture traps, and humidity control if needed. The sealed system prevents moisture pickup and dust emission. Nitrogen gas conveying is optional for sensitive formulas. In food and pharmaceutical grades, stainless steel construction meets sanitary standards.

Bridging and arching are common in CMC storage. Our silos and hoppers use proper cone angles and low-friction linings for mass flow. We install fluidizing pads, vibrators, or air cannons to prevent blockages. Rotary valves and screw feeders are sized to ensure continuous, uniform discharge into the conveying line even with batch variations.

Automation is key. The PLC-based panel monitors pressure, vacuum, motor current, filter pressure, temperature, and material level in real time. It adjusts air volume, valve positions, and feeder speed for stable throughput. The system can integrate with DCS, MES, or ERP and supports remote access, data logging, and alarm notification.

Safety is critical for fine organic dust. We provide antistatic filter media, grounding, explosion venting, and explosion-proof electrical parts as needed. Pressure relief and interlock controls prevent overpressure. The dust-tight system protects workers and keeps the plant clean. Sanitary designs and clean-in-place options are available for food and pharmaceutical grades.

Our CMC powder conveying systems are used in construction chemicals, detergents, food additives, pharmaceuticals, ceramics, oilfield additives, and textiles. We handle design, manufacturing, installation, commissioning, training, and after-sales support. Every system is factory-tested and backed by experienced engineers.
