This dense phase solid material pneumatic conveying system adopts compressed air plug-type conveying structure, supporting ultra-long-distance and high-output transport. Max horizontal conveying distance reaches 1500m with over 100t/h capacity. Materials move at low speed to avoid breakage and abrasion, featuring 10–85kg/kg high material-gas ratio to cut air & power cost. Fully sealed pipeline realizes dust-free, low-noise operation, with PLC intelligent control. Widely used in chemical, plastic, rubber and food industries for powder & granule delivery.

The solid material dense phase pneumatic conveying transport feeding system is a high-pressure positive-pressure bulk material conveying device, specially developed for long-distance, large-capacity powder and granular raw material transportation. Different from dilute phase high-speed conveying equipment, it uses a pressure vessel to inject compressed air into the pipeline, pushing materials forward in continuous plug slugs, which fundamentally reduces the collision friction between materials and pipe walls.The system can realize horizontal conveying up to 1500m and vertical lifting height of 50m, with single-line hourly output exceeding 100 tons. It is compatible with fragile raw materials, abrasive particles, lump materials and mixed compound powder. The whole pipeline is fully closed without powder leakage, with low operating noise and few wearing spare parts, greatly reducing long-term factory maintenance labor and spare part expenditure.Equipped with exclusive full pipeline intelligent technology, matched PLC controller and special operation software, the equipment can real-time adjust pipeline internal pressure and material flow speed. Double parallel pipeline design plus distributed booster valves further lower air consumption, suitable for long-distance multi-station batching, mixing and feeding in chemical, plastic, rubber, food processing industries. It can be perfectly matched with weighing scale, mixing machine, extruder and silo to form a complete automatic raw material handling production line.
Ultra-low conveying velocity leads to minimal material degradation; fragile, colored, easily broken raw materials will not pulverize during transportation.
Wide material compatibility: applicable to fragile, abrasive, lump, high bulk density powder and all kinds of mixed compound materials.
Extremely low pipeline wear, greatly extend service life of steel conveying pipes.
Simple structure with few wearing parts, minimum daily maintenance workload and low after-sale cost.
Fully closed circulating pipeline, zero material spillage and dust emission, keep workshop clean and meet environmental protection standards.
Low air flow rate design, the whole machine runs quietly without harsh operation noise.
Ultra-low gas consumption, high material-gas ratio reduces factory compressed air and electricity operating cost.

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.
