Product Overview
Dense phase pneumatic conveying system is a high-efficiency, low-loss, dust-free bulk material conveying equipment. Adopting pressure vessel plug-type pneumatic conveying mode, it transports powder and granular materials through compressed air propulsion. With low-speed conveying design, it effectively protects material integrity without crushing or deterioration. Equipped with PLC full pipeline intelligent control technology and dual parallel pipe structure, the system realizes long-distance, large-capacity, low-energy and low-maintenance automatic conveying. It is widely applicable for conveying fragile, abrasive, high-density and blended materials, perfectly matching the supporting transportation needs of mixers, batching scales and other industrial equipment.
System features
This kind of conveying system works by pushing the material along the pipe in a plug form, with the help of compressed air blown into the pipeline by a pressure vessel.
Dense phase pneumatic conveying systems can be used to transport a large range of bulk materials, both in the form of powders or granules. They can reach distances longer than 500 metres and capacities over 100 t/h.
The low conveying speed used in dense phase pneumatic systems helps preventing the material degradation and preserves the product quality and integrity. It is suitable to handle any kind of product, including fragile, abrasive and lumpy materials and blends.
Dense phase transport has a high product/air efficiency ratio. The indicative ratio of air or gaseous fluid to the product is about 30L of gas per 1Kg of product. Thanks to the reduced amount of air needed, this system allows reduced energy consumption.
Pneumatic conveying systems offer the benefit of low maintenance costs: the number of spare parts and maintenance services needed to maintain the system running is limited.

Full pipeline dense phase pneumatic conveying
The Full Pipeline system is an innovative technology which allows to control the pressure and speed inside the pipeline through PLC and dedicated software.
The transport cycle is carried out with the full product pipeline to achieve a significant air and energy saving. Full pipeline systems are used to handle fragile and abrasive materials over long distances.
the line consists of two parallel pipes: one pipe is used to convey the material to the destination, the other is used to feed air into the pipeline through the boosters. In order to reduce air consumption and maximize efficiency, pneumatic electro valves are placed before each destination.
Product Advantages
1. Low material damage and high yield. Low-speed plug conveying avoids material fragmentation, degradation and deformation, fully protecting fragile, abrasive and easily broken materials.
2. Super strong material adaptability. It supports powder, granule, lump, blended materials and high bulk density materials, covering most industrial bulk materials.
3. Long-distance and large-capacity conveying. The maximum horizontal conveying distance reaches 1500m and vertical height 50m, with hourly capacity exceeding 100t/h, meeting large-scale production demands.
4. Energy-saving and high-efficiency operation. High material-gas ratio reduces air consumption, effectively lowering overall energy consumption and production operating costs.
5. Dust-free and environmentally friendly production. Fully closed pipeline conveying realizes no material spillage and no dust emission, improving workshop environment.
6. Low noise and stable operation. Low air flow rate and low-speed operation reduce equipment noise, suitable for factory continuous operation.
7. Low maintenance cost. The whole system has low wear and tear, few vulnerable parts and simple daily maintenance, saving later operation cost.
8. Intelligent and precise control. Supporting PLC and professional software to adjust pipeline pressure and speed, realizing stable and controllable conveying process.
