Dense phase pneumatic conveying is a proven and efficient method for moving dry bulk powders and granular materials through enclosed pipelines. Unlike dilute phase conveying, dense phase technology uses low gas velocity and high pressure to transfer material as slugs or plugs. This approach reduces product degradation, lowers pipe wear, and controls dust emission. Our company specializes in designing and manufacturing dense phase conveying systems that are customized to each material's particle size, bulk density, moisture content, and flow behavior. Whether you need a single line or a complex multi-line transfer station, we can provide reliable, safe, and cost-effective solutions for your bulk handling application.

A complete dense phase conveying system consists of a pressure feed vessel, high-pressure air source, valve skid, conveying pipeline, diverters, and receiving filter. The material is loaded into the vessel, sealed, and pressurized. Then the control system opens the discharge valve in a controlled sequence, allowing material to move through the pipe as dense slugs. Booster fittings along the line maintain flow and prevent plugging. At the receiving end, a cyclone or bag filter separates the product from the transport air. Each component is selected based on material abrasiveness, temperature, particle shape, and explosion safety. This ensures stable operation, minimal product loss, and low maintenance.

The key benefits of dense phase pneumatic conveying are low gas velocity, gentle product handling, and low energy consumption. Gas velocity can be as low as 2 to 5 meters per second for many powders, which greatly reduces particle impact and pipe erosion. This makes it suitable for fragile, abrasive, cohesive, or heat-sensitive materials. Dense phase systems can transport material over long distances and at high capacities while maintaining product quality. Because the system uses less conveying air, downstream filters last longer and energy costs are reduced. The fully enclosed pipeline also prevents contamination and dust leakage, creating a safe and clean working environment. These systems are widely used for cement, fly ash, titanium dioxide, carbon black, milk powder, pharmaceuticals, and plastics.

Our engineering team provides complete dense phase conveying solutions for power generation, cement, mining, chemical, food, petrochemical, and pharmaceutical industries. We offer turnkey projects that include storage silos, pressure vessels, pipe networks, instrumentation, control panels, and structural supports. During the design process, we analyze the material's flowability, particle size distribution, bulk density, and moisture. We then determine the optimum conveying distance, elevation change, capacity, and air consumption. Depending on your material and site constraints, we may recommend a pressure vessel system, external bypass type, or full-line conveying system. For abrasive materials, we use wear-resistant pipes and long-radius bends. For hygienic applications, we design smooth, easy-to-clean surfaces and dust-tight connections. We also provide system upgrades, spare parts, and replacement components for existing conveying installations. Our team supports each project from initial consultation through installation, startup, and operator training.

As a professional dense phase conveying system manufacturer, we are committed to international quality standards. Our production facility applies advanced welding and fabrication techniques, and each pressure vessel is fully tested to ensure safe operation. We provide complete commissioning, operator training, technical documentation, and after-sales support. Our spare parts inventory minimizes downtime, and our engineers are available for on-site troubleshooting and process optimization. We understand that every project has unique requirements, so we offer flexible pricing and tailored proposals. Whether you need a standard conveying unit or a fully automated material handling line, we can deliver a competitive solution. We believe that long-term success comes from reliable equipment, responsive service, and mutual trust. We also provide detailed installation drawings, manuals, and remote or on-site assistance whenever needed.
