This series of equipment is suitable for long- distance transportation and lifting of granular, powdery, loose and dry self flowing materials (water content ≤1.5%).

The device adopts high- pressure dense phase pneumatic conveying of granular materials. The materials are suspended in the pipeline and advance at low speed. It has the advantages of simple and compact structure, long conveying distance， flexible setting of discharging point, small wear of pipeline and spherical elbow, convenient maintenance and easy automatic control. ，

It is convenient to realize multi-point unloading and alternate order and se lective transportation of two different materials.
