Sodium carboxymethyl cellulose (CMC) is a water-soluble cellulose ether widely used in food, pharmaceutical, paper, textile, oil drilling, and ceramics industries. As a fine powder or granule, CMC is hygroscopic and cohesive, so its conveying process must prevent moisture pickup, dust escape, and pipe blockage. Our customized CMC pneumatic conveying solution delivers closed, automated, and reliable transfer from dryers, screeners, or storage silos to packaging hoppers and downstream equipment.

CMC particles can easily absorb moisture, form lumps, adhere to pipe walls, and bridge inside hoppers. A standard pneumatic conveyor is often unsuitable for this material. Our engineers first evaluate moisture content, bulk density, particle size distribution, flowability, and abrasiveness. We then design a dense-phase or dilute-phase conveying system according to required capacity, conveying distance, plant layout, and product characteristics.

The conveying system is driven by a roots blower or screw compressor that supplies clean and dry compressed air. CMC powder is fed at a controlled rate through a blow tank, rotary airlock, or venturi feeder. It is fluidized and transported through carbon steel or stainless steel pipelines to the receiving point. A cyclone separator and pulse-jet cartridge dust collector then separate product from the conveying air, allowing material to discharge into a surge hopper or packaging machine while clean air is released safely.

For fragile or moisture-sensitive CMC granules, dense-phase conveying at low velocity and high material-to-air ratio is preferred. This mode reduces particle degradation, pipe wear, and moisture contact. For fine CMC powder, dilute-phase conveying is suitable over short distances and moderate capacities. All key parameters, including conveying velocity, air pressure, feed rate, and pipe diameter, are calculated using process simulation and practical experience to avoid dead zones, blockages, and cross-contamination.

Key components include a blow tank, rotary airlock valves, pressure and vacuum relief valves, diverter valves, anti-wear pipeline bends, flexible connectors, slide gates, level sensors, and pressure transmitters. A PLC-based control panel automatically regulates the conveying cycle, alarms for abnormal conditions, and records production data. The system can be integrated with vacuum mixers, granulators, fluid-bed dryers, and automatic packaging lines to form a complete production process.

Every CMC handling project is unique. Conveying distance, vertical lift, number of destination points, available air pressure, and site layout all influence the final design. Our solution can include single-line or multi-line conveying, one-to-many or many-to-one routing, temporary storage, iron removal, screening, dehumidification, and weighing systems. For combustible organic dust environments, explosion protection, earthing, static control, and flameproof electrical components can be added to meet ATEX or local safety standards.

The CMC conveying system is easy to clean and maintain. Quick-release couplings, inspection doors, and smooth pipe interiors reduce downtime and simplify product changeover. Contact parts can be manufactured from SS304 or SS316L stainless steel with food-grade or pharmaceutical-grade surface finish. For hygienic applications, the fully sealed system supports CIP/SIP cleaning and complies with GMP, FDA, and food safety requirements.

This customized solution eliminates manual handling, reduces labor costs, prevents material spillage, and maintains a clean, dust-free workplace. It is energy-efficient because the conveying parameters are optimized specifically for CMC, while automated feeding improves accuracy and consistency.
