Abstract
The invention relates to a separator for separating a conveyed medium, preferably air, from a conveyed material ( 4 ). Said separator comprises a container ( 1 ) which has at least one feed line ( 3 ) for the conveyed medium/conveyed material mixture, at least one outlet for the conveyed material ( 4 ), and at least one outlet ( 8 ) for the conveyed medium. In order to avoid abrasion damage at high conveying speeds or to ensure that said abrasion damage occurs at most only to a small extent, while nevertheless ensuring that the conveying medium and conveying material are reliably separated, an impact wall ( 14 ), which adjoins a cover wall ( 15 ) at an angle thereto, is located in the housing ( 1 ) opposite and at a distance from the outlet end ( 10 ) of the feed line ( 3 ) in the inflow direction ( 13 ) of the conveyed medium/conveyed material mixture. Said impact wall covers the inflow path of the conveyed medium/conveyed material mixture, blocking it from the outlet ( 8 ) for the conveyed medium. The conveyed material ( 4 ) hits the impact wall ( 14 ), which causes the kinetic energy of the conveyed medium to dissipate. The speed of the conveyed medium reduces very quickly after exiting the feed line ( 13 ), meaning that it cannot entrain any conveyed material.
