Pneumatic conveying scheme for sodium carboxymethyl cellulose

In the powder processing and transportation sector, sodium carboxymethyl cellulose (CMC), as a common fine chemical raw material, often faces numerous challenges during its transportation process. Many companies often experience equipment blockages, dust pollution, and low conveying efficiency during production due to material characteristics, seriously affecting production rhythm and product quality. To address these pain points, Head Powder, leveraging years of industry experience, has launched a customized sodium carboxymethyl cellulose pneumatic conveying system to help enterprises achieve efficient, clean, and stable material delivery.

Customer pain points

Sodium carboxymethyl cellulose has strong hygroscopicity, is prone to caking, and has fine powder dispersion. Traditional mechanical conveying methods (such as screw and belt conveying) are prone to issues such as material sticking to walls, pipe blockages, and scale clumping. Frequent cleaning and maintenance are required, and open conveying can easily cause dust pollution, which not only affects the workshop environment but also poses safety and occupational health risks. At the same time, if materials become damp during transportation, it directly leads to a decline in quality and increases production costs. How to achieve sealed, continuous, and low-loss automated conveying has become a core demand for industry users.

Material characteristics

Sodium carboxymethyl cellulose is a white or pale yellow powdery solid, usually with particle sizes between 40~200 mesh and an apparent density of about 0.4~0.8 g/cm³, exhibiting strong hygroscopicity. In humid environments, clumps easily form, significantly reducing fluidity. Additionally, this material is prone to electrostatic adsorption in high-speed airflow, which places high demands on the material and airflow speed of the conveying pipeline. Properly handling these characteristics is the key to the success of pneumatic conveying solutions.

Product Introduction

The sodium carboxymethyl cellulose pneumatic conveying system launched by Head Powder uses sealed pipeline conveying methods of positive or negative pressure, allowing for customized design based on on-site process conditions and material characteristics. The system consists of core components such as transmitters, pipelines, separators, dust collectors, and automatic control systems. The entire conveying process is completed within sealed pipelines, effectively isolating external moisture and pollution sources, suitable for various conveying distances and conveying volume requirements. The equipment can be flexibly integrated into existing production lines, achieving a fully automated closed loop from feeding to measurement and batching.

Product advantages

To address the pain points of sodium carboxymethyl cellulose being prone to moisture absorption, caking, and dust generation, Head Powder Customization Solutions offers multi-dimensional solutions:

• Moisture-proof sealing design: Pipes and components are made of food-grade stainless steel, equipped with dehumidifying air sources and insulation systems to reduce the risk of moisture absorption and caking at the source.
• Optimize airflow parameters: Through computational fluid dynamics (CFD) simulation, the air-to-solid-gas ratio is reasonably set to avoid electrostatic adsorption or crushing caused by excessively high flow rates, while maintaining stable fluidization.
• Efficient dust removal and recovery: Equipped with a pulse reverse blow cartridge dust collector to purify dust-laden gases, with dust emission concentrations below 10 mg/Nm³, meeting environmental protection requirements, and recyclable materials.
• Intelligent control and data traceability: Uses PLC+HMI integrated control system to monitor conveying pressure, flow, temperature, and other parameters in real time, with fault alarm and historical data recording functions, reducing manual intervention and improving production management efficiency.

Through these targeted designs, the Head Powder Carboxylmethyl Cellulose Sodium Pneumatic Conveying System helps enterprises reduce equipment failure rates, minimize material loss, improve workshop environments, achieve continuous and stable production, and assist companies in reducing costs and increasing efficiency in powder conveying.
