Polystyrene powder is a lightweight, free-flowing material widely used in foam production, packaging, insulation, and molding processes. An efficient pneumatic conveying system is essential to transport this powder safely and consistently from storage, milling, or blending areas to process equipment. Our customized solution ensures low degradation, minimal dust emission, and stable feeding under demanding production schedules.

We offer both dilute-phase and dense-phase pneumatic conveying options tailored to polystyrene powder characteristics. Dilute phase is suitable for low-capacity, short-distance transfer with high air velocity. Dense phase operates at low speed and high pressure, reducing particle attrition and energy consumption. The selection is based on particle size, bulk density, moisture content, conveying distance, and required throughput.

Each system includes a positive displacement blower or compressor, rotary airlock valve, feed hopper, conveying pipeline, receiver cyclone or bag filter, and PLC control panel. The powder enters the pipeline through a rotary valve or venturi feeder and is carried by compressed air or inert gas. A dust collector at the discharge point separates the powder from the conveying air and releases clean exhaust. Pressure transmitters and flow sensors monitor line pressure, air velocity, and filter differential pressure to maintain optimal operation.

Polystyrene powder can be combustible when suspended in air at certain concentrations. Therefore, our conveying systems are designed with explosion protection measures. These include static grounding, explosion-relief panels, flame-retardant filters, oxygen level monitoring, and nitrogen purging options. All components comply with ATEX or equivalent standards. The control system automatically shuts down the blower and closes isolation valves if abnormal pressure or temperature is detected.

Material handling components are selected to resist abrasion and prevent build-up. The pipeline uses smooth-bore stainless steel or aluminum tubing with radiused bends to reduce wear and avoid dead zones. Rotary airlock valves are machined with close clearances to minimize air leakage and product degradation. Flexible connections and sight glasses allow easy inspection. All contact surfaces are designed for quick cleaning when product grade changes are required.

Our conveying solution integrates seamlessly with upstream and downstream equipment. The PLC controller can communicate with existing plant automation via Modbus, Profibus, or Ethernet IP. It provides real-time trends, alarms, and production reports. Variable frequency drives on the blower and feeder allow precise capacity adjustment. Remote control and diagnostics reduce downtime and improve overall equipment effectiveness.

Custom engineering is the core of our service. We analyze the physical properties of your polystyrene powder, including particle size distribution, bulk density, angle of repose, and abrasiveness. We then calculate the minimum conveying velocity and pressure drop for the selected route. This ensures reliable conveying, low product damage, and reduced energy consumption. Our team provides layout drawings, piping isometrics, and support steel details.

Applications include polystyrene bead conveying, expandable polystyrene powder transfer, finished powder packing, and waste regrind recycling. We provide installation supervision, commissioning, operator training, and after-sales support. Our modular design also allows future expansion.

Choosing our polystyrene powder pneumatic conveying solution reduces manual handling, improves workplace safety, and ensures consistent product quality. The enclosed system prevents contamination and dust leakage. Low-energy fans and optimized pipe routing lower operating costs. Robust construction and intelligent controls deliver dependable performance for years.
