Abstract (en)

[origin: WO2020151931A1] The present invention relates to an air jig for the dry processing of raw materials, in particular coal, comprising: at least one material-feeding device (1); at least one jigging-material carrier (2), which is provided with openings; an air funnel (3), which is arranged below the jigging-material carrier (2) and by means of which an air flow can be fed as working air (4) to the jigging-material carrier, which working air is composed of a partial flow constantly flowing through the jigging-material carrier (2) and a pulsing partial flow superposed thereon, such that the working air (4) can flow through the material fed onto the jigging-material carrier (2) and said material can be stratified into a heavy material layer (5) acting as a jig bed and into a light material layer (6) lying thereon; and a discharge device (7) for the heavy material and light material stratified on the jigging-material carrier (2) during the jigging process.
