Purposes: Used for delivery of new sand, reclaimed sand, old sand and other dry bulk particles crushed materials.

Features: the entire transportation process is fully automatic operation. Can be a long-distance transportation, a pneumatic transport apparatus can be completed to the point of use of one or more of the material transport through the valve on the pipe set fork and unloading, can freely choose the number of the discharge point. The materials full pipeline of high-density, low-speed transportation, small pipelines wear, less material crushing, low energy consumption, small changes of temperature of the sand in the transportation process. No dust escaping to keep work environmental health in the entire transportation process. Using a the special spherical elbow or R-bend in spherical three-way spherical unloader, long service life. Arrangement of flexible, automatic control, be left unattended
