Stearic acid powder is widely used in rubber, plastics, cosmetics, pharmaceuticals, and chemical industries. Its fine particle size, low bulk density, and cohesive nature make conventional mechanical conveyors prone to bridging, caking, dust leakage, and contamination. Pneumatic conveying provides an enclosed, clean, efficient transfer from storage to processing equipment.

Our custom pneumatic conveying solution is engineered specifically for stearic acid powder. We offer both dense phase and dilute phase systems. Dense phase uses low velocity and high pressure to move material gently, reducing degradation, segregation, and pipeline wear. Dilute phase uses high-velocity air for short distances and moderate capacities. Our engineers select the optimal mode based on density, particle size, moisture, distance, and layout.

Main components include a feed hopper, rotary airlock valve, roots blower or screw compressor, conveying pipeline, filtration receiver, dust collector, level sensors, and PLC control panel. The hopper ensures stable feeding. The airlock valve seals the system and controls feed rate. The blower supplies airflow and pressure. The receiver separates powder from air, and the dust collector prevents emissions.

Stearic acid powder tends to stick to pipe walls and form deposits. To prevent this, our design uses surface-polished stainless steel tubing, anti-static piping, and large-radius smooth bends. Air velocity is optimized to keep powder suspended without excessive wear. Fluidizing pads, vibrators, or purge points are installed at critical locations. For humid conditions, heating or insulation can be added to prevent moisture absorption and caking.

The system can meet strict hygiene and safety standards. Contact parts are available in SS304 or SS316L stainless steel with sanitary finishes for food, pharmaceutical, and cosmetic applications. The enclosed line minimizes dust release and protects operators. Explosion protection, including vents, flame-arresting filters, static grounding, and pressure-resistant equipment, can be added to comply with ATEX and local regulations.

PLC control ensures automatic operation, real-time monitoring, and alarm management. It controls the blower, airlock valve, and discharge equipment while monitoring pressure, temperature, and filter status. The system can be integrated with production lines and central control platforms for remote operation and data collection. Variable frequency drives adjust speed and reduce energy consumption.

Our conveying systems are used in rubber mixing, plastic compounding, pharmaceutical dosing, and cosmetic manufacturing. They accurately transfer stearic acid powder to mixers, extruders, and batching vessels without loss or cross-contamination. Capacities range from a few kilograms per hour to several tons per hour. We provide layouts, piping diagrams, electrical schematics, installation support, and commissioning.

To build a complete turnkey system, we offer bag dump stations, big bag unpacking, storage silos, vacuum receivers, in-line sieves, metal separators, and automatic weighing or batching systems. These components reduce manual labor, improve material efficiency, and maintain accurate formulas. For oxygen-sensitive processes, nitrogen gas can be supplied to create an inert atmosphere and prevent oxidation.

Maintenance is simple because of modular design and inspection openings. The airlock valve can be serviced without removing the pipeline. Filters are cleaned automatically by pulse jet and are easy to replace. Pipes are smooth and removable. We provide manuals, training, commissioning, spare parts, and technical support. With preventive maintenance, the system runs reliably for many years.

Selecting the right pneumatic conveying system is essential for stearic acid powder projects. Our engineering team can test your material in a pilot system to determine optimal conveying parameters. We provide a complete proposal, project schedule, and after-sales service. From design to operation, our goal is a safe, efficient, cost-effective solution.
