Silicon carbide (SiC) particles are widely used in abrasive production, refractory manufacturing, ceramics, metallurgy, and advanced materials. Because SiC is extremely hard and abrasive, mechanical conveyors often wear quickly and cause dust leakage. A pneumatic conveying system moves SiC through a sealed pipeline using controlled airflow, protecting both material and environment. We provide complete pneumatic conveying solutions, including testing, equipment manufacturing, installation, and commissioning.

Our pneumatic conveying systems include dilute phase and dense phase options. Dilute phase uses high-velocity air to suspend and move particles; it suits short distances, moderate capacities, and impact-tolerant materials. Dense phase uses low-velocity, high-pressure air to push material through the pipe as a plug, reducing particle degradation, pipe wear, and energy. We also supply pressure and vacuum systems. Pressure conveying moves material from one point to multiple destinations; vacuum conveying draws material from multiple sources to a central receiver.

Each system includes a rotary airlock, blow tank or vacuum receiver, pipes, diverter valves, cyclone separator, bag filter, level sensors, and PLC controls. For abrasive SiC, we use ceramic-lined pipes, hardened elbows, and wear-resistant surface treatments. The rotary airlock ensures steady feeding and prevents leakage. The bag filter captures dust and keeps emissions within limits. Pipework can be installed overhead, along walls, or under the floor, so the system fits existing plants with limited space.

Every silicon carbide particle pneumatic conveying solution is customized to your material and site conditions. Our engineers analyze particle size distribution, bulk density, moisture content, flowability, abrasiveness, and conveying distance. These data determine pipe diameter, air velocity, pressure drop, and capacity. We design single-line or multi-line systems for storage silos, hoppers, mixers, packaging machines, or production lines. The PLC system provides automatic operation, HMI touchscreen, remote monitoring, alarms, and data recording, ensuring stable performance and simple maintenance.

Key advantages include fully enclosed conveying, no dust leakage, low material loss, flexible routing, and small floor space. The sealed system prevents contamination and moisture absorption. Pipework can be routed overhead, along walls, or under the floor to save space and simplify installation. Compared with screw conveyors and bucket elevators, pneumatic conveying has fewer moving parts, lower maintenance costs, and can serve multiple points with high flexibility. It reduces manual handling, improves safety, and supports continuous production.

Typical parameters are capacity 0.5–50 t/h, distance 5–300 m, air velocity 8–30 m/s in dilute phase and 2–8 m/s in dense phase, and solid-to-air ratio 1–10 or 10–30 respectively. Pipe materials can be carbon steel, stainless steel, or ceramic-lined. Control power is AC 220V or AC 380V. Inert gas conveying is available for fine SiC powder or oxygen-sensitive materials. Explosion-proof components, anti-static grounding, and pressure-relief devices can be added for hazardous areas.

These systems handle SiC grit, powder, and granules in abrasive, ceramic, refractory, and advanced material plants. Applications include kiln furniture, crucibles, wear-resistant linings, filters, sintering furnaces, and high-temperature processing. Every system is tested with real material before delivery. We also provide on-site surveys, installation guidance, training, and after-sales service. Contact us to discuss your silicon carbide particle conveying project and receive a tailored proposal.
