White carbon black, also known as precipitated silica, is a finely divided powder used in rubber, tire, silicone, toothpaste, paint, and plastic industries. Its low bulk density, high porosity, and tendency to absorb moisture make it difficult to handle with mechanical conveyors. Pneumatic conveying offers a clean, safe, and efficient solution for transferring this challenging material throughout a production plant.

Choosing the right conveying system is critical for manufacturers of white carbon black. A well-engineered pneumatic system ensures smooth material transfer over long distances, reduces downtime, maintains product quality, and lowers energy consumption. Our customized solutions are designed for the unique properties of white carbon black, such as poor flowability, high abrasiveness, and electrostatic charging. We combine advanced technology with practical experience to build reliable systems for continuous industrial operation.

Dilute phase pneumatic conveying is a common choice for many white carbon black applications. A high-velocity air stream carries the powder through the pipeline in suspension. This method is suitable for short to medium distances and less abrasive materials. It offers lower initial investment and simple installation. However, because white carbon black is light and fluffy, careful attention must be paid to air velocity, pipeline diameter, and bend design to prevent degradation and blockages.

Dense phase pneumatic conveying is often preferred for white carbon black. In this system, material is pushed through the pipeline at low velocity using compressed air or a pressure vessel. This approach reduces product degradation, lowers air consumption, and minimizes wear on components. Dense phase can handle longer distances and elevation changes with less energy. Our engineers select the optimal conveying mode based on material properties and site conditions.

A complete system includes feeding devices, conveying pipelines, air movers, and separation equipment. Rotary airlock valves or screw feeders control the material entering the line. Positive displacement blowers or compressors provide the motive force. Cyclones, filter receivers, and cartridge filters separate the powder from the air. Control panels and sensors monitor pressure, flow, and level to ensure stable operation. Every component is selected for durability, easy maintenance, and compatibility with white carbon black.

Key design considerations include conveying distance, elevation change, conveying rate, and plant layout. Moisture content significantly affects flow behavior; therefore, dehumidifiers or dry-air purge systems may be added. Since white carbon black generates static electricity, conductive pipelines, grounding, and anti-static filters are essential for safety. The system must also be sealed to prevent dust leakage and protect workers from airborne particles.

We provide fully customized white carbon black conveying solutions. Options include single-line or multi-line systems, manual or automatic control, and batch or continuous conveying. We integrate weighing, dosing, mixing, and packing equipment to form a complete process line. Whether for a pilot plant or a large industrial facility, our systems fit seamlessly into existing operations and comply with safety and environmental regulations.

Dust and explosion protection are essential in white carbon black conveying. The fine powder can form dust clouds that are hazardous in the presence of an ignition source. Our systems include explosion venting, suppression, and isolation devices, plus pressure and temperature monitoring. High-efficiency filtration ensures clean exhaust air and compliance with emission standards. We provide comprehensive support from consultation to commissioning, including material testing, flow simulation, installation supervision, and operator training.
