This sealed transport dense phase pneumatic conveying system is engineered for efficient long-distance transportation of various powdered materials including fly ash, lime powder, cement, aluminum powder, mineral powder, saw dust, and straw. The system features compact design with minimal footprint, flexible pipeline layout, and complete PLC automation for reliable operation.

• Cost-effective installation and operation with reduced capital investment
• Fully enclosed design ensures hygiene and prevents material contamination
• Flexible routing capability with tubes that navigate multiple floor levels and angles
• Complete PLC automation for reliable, maintenance-friendly operation
• Superior powder handling compared to mechanical conveyors
• Comprehensive system components including compressed air source, pneumatic vessel, control cabinet, and conveying pipes

Materials enter the sending tank through double butterfly valves, with displaced air released via exhaust valves. When the tank reaches 90% capacity, valves seal and compressed air pressurizes the system. At preset pressure levels, discharge valves open automatically, transporting materials in plunger form through pressurized pipelines until complete material transfer.

• High conveying pressure up to 0.5 MPa for long-distance transport (100-300 m)
• Low flow rate with high solid-gas ratio and minimal gas consumption
• Excellent material adaptability for fragile and abrasive materials
• One-to-multi-point feeding capability
