Process of stalling the speeds of articles to be conveyed in a pneumatic conveying system and a device therefor

摘要

A process of stalling the speeds of articles to be conveyed in a pneumatic conveying system, wherein the speeds of the articles conveyed by conveying power wind through a transporting piping are stalled at a position close to the outlet of the transporting piping. According to this stalling process, air vents are formed at positions close to the outlet of the transporting piping, air having a wind flow rate higher than the wind flow rate of the conveying power wind is sucked through the air vents, whereby the speeds of the articles are stalled by counter flow wind flowing in through the outlet of the transporting piping.
