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. An open space is formed under the inclined guide plate so that the materials aren't damaged when the slide damper is moved. 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.
