CMC (sodium carboxymethyl cellulose) powder is widely used in industries such as chemicals, food, and pharmaceuticals, but its unique physicochemical properties pose many challenges during transportation. The following explains common customer pain points, material characteristics, product solutions, and advantages.

Customer pain points

Many companies face the following issues during CMC powder conveying: materials easily absorb moisture and cause clumping, leading to pipeline blockages; Severe dust swirling polluted the production environment and threatened operator health; Unstable conveying speed, affecting downstream process continuity; Equipment wears out quickly and has high maintenance costs. These issues directly restrict the stability of production efficiency and product quality.

Material characteristics

CMC powder is a typical highly hygroscopic and low-flowability powder, with fine particle size (usually above 100 mesh) and low bulk density (about 0.3–0.6 g/cm³). It features strong adhesion, easy static electricity, and gelation upon contact with water. These characteristics make it difficult for conventional mechanical conveying methods (such as screws and belts) to operate properly, while pneumatic conveying is a more suitable choice.

Product Introduction

The CMC pneumatic powder conveying system provided by Head Powder is a complete solution specially designed for the above material characteristics. The system uses sealed pipeline conveying, powered by compressed air or inert gas. By accurately controlling the gas-solid ratio and flow rate, it achieves smooth and dust-free delivery of CMC powder from the raw material silo to the terminal equipment. Core components include: anti-arching silos, fluidized beds, rotary feeders, Roots blowers/air compressors, cyclones or baghouse dust collectors, electrical control systems, and more. The system can be customized according to actual needs such as production capacity, conveying distance, and pipeline route.

Product advantages

To address customer pain points, Head Powder has introduced the following solutions:

• Moisture-proof design: The system is equipped with a dehumidifying air source and insulation pipelines, combined with micro-positive pressure protection in the silo to reduce the risk of CMC moisture absorption and caking.
• Highly accurate speed control: The variable frequency speed feeder works in conjunction with the air volume control valve, helping to transport materials at a constant speed and supporting batching accuracy in downstream processes.
• Dust-free operation: The entire system operates under either negative or positive pressure in a sealed operation, combined with a high-pressure pulse baghouse dust collector, with dust emission concentrations below 10 mg/m³, meeting environmental protection and occupational health requirements.
• Low-wear structure: The inner walls of the pipes are treated with wear-resistant ceramic linings or supersonic spraying, optimizing the bending radius to significantly extend equipment service life and reduce maintenance frequency.

Head Powder has many years of experience in powder conveying projects and can provide full-process services for different process scenarios, from solution design and equipment manufacturing to installation and commissioning, helping enterprises achieve efficient, clean, and stable CMC powder conveying.
