Abstract (en)
[origin: WO2011147504A1] The invention relates to an air jigging machine, comprising a material input device, at least one jigging-material carrier provided with openings, and a dispensing device for heavy material and light material, an air flow flowing through the jigging-material carrier as working air, the air flow being composed of a partial flow that constantly flows through the jigging-material carrier and a pulsed partial flow superposed thereon, characterized in that at least two jigging-material carriers (15, 16), which are arranged one over the other at a distance from each other and through which the air flow introduced into the air funnel (28) flows and which each have a material input (13, 14) and an dispensing device (20), are arranged above the air funnel (28), which is connected to an air supply line (32) that has a pulsing valve (34) inserted therein. The intermediate space between the jigging-material carriers (15, 16) is enclosed by an outer wall (40), and in order to increase the air amount to be supplied to the upper jigging-material carrier (15), at least one bypass air line (50a, b) that bypasses the lower jigging-material carrier (16) branches off from the air supply line (32) downstream of the pulsing valve (34) and is connected to the intermediate space between the two jigging-material carriers (15, 16) in such a way that an additional working air flow can be introduced through the bypass air line (50a, b) into the intermediate space between the jigging-material carriers (15, 16).
