Pneumatic conveying system |
摘要 |
A pneumatic conveying pipe extending through fine-grained material in a pressurized storage tank and having ports in its side wall through which fine-grained material is forced by pressure in the storage tank. After being forced through the ports, the fine-grained material is conveyed along the pipe by an airstream. An annular valve abuts the inner periphery of the conveying pipe and is movable along the axis of the pipe from a position where it covers the ports to a position where the ports are exposed.
