Abstract
An apparatus for separating tramp particles from comparatively lighter particles of product being conveyed, both entrained in a fluid stream within a pipeline of a pneumatic conveying system, generally comprising a passageway through which the fluid stream with the entrained particles is conducted, the fluid passageway including a section having a progressively increasing cross-sectional area whereby the velocity of the fluid stream is caused to decrease as it traverses through the passageway, a baffle disposed in the path of the fluid stream traversing through the passageway for laterally deflecting the fluid stream flowing at a reduced velocity whereby the tramp particles are caused to gravity fall from the fluid stream while the product particles remain entrained therein, and a receptacle for receiving the tramp particles discharged from the fluid stream.
