Abstract: A pneumatic transport system for powdered materials for quantifying and pneumatically transferring powdered materials. When materials are fed above an inclined guide plate in a material feeder with its bottom opening closed by a valve plug, a slide damper is slid to divide the materials in the feeder vertically.

When the valve plug is retracted, the materials under the slide damper are fed into a transport plug housed in a plug setting portion. The transport plug is pneumatically transported into a material discharge port by compressed air supplied by an air supply. After the transportation is finished, the transport plug is returned into the plug setting portion.
