There is disclosed a method and apparatus for separating stones, fibers and plastics from biodegradable material. In an embodiment, the apparatus comprises: an inclined trough having a feed entry at a top end for receiving the feed material, the inclined trough including a plurality of riffles angled to at least partially hinder and unsettle a flow of the feed material flowing down the inclined trough; one or more vibratory motors configured to induce a vibration in the inclined trough; one or more blowers configured to generate an air flow through overhead air vent nozzles positioned over the inclined trough and directing the air flow to one side of the inclined trough; and a material resilience separator for separating the contaminants from the biodegradable materials in the remaining material.

The present invention relates to an air jigging machine for the dry processing of raw materials, particularly 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.

Sifting apparatuses for stratifying raw material including a material feed-in device, a material support unit, a gas plenum, a discharge control mechanism, and a reservoir are described. The material support unit receives material from the material feed-in device and has a surface with a plurality of openings for a gaseous medium introduced from underneath the material support unit, thereby effecting loosening and stratification of the material into a layer of relatively heavier material, and a layer of relatively lighter material atop the relatively heavier material. The introduced gaseous medium originates in a pump, is collected in a pressurized reservoir, and is controlled by a metered valve prior to introduction to the material support unit.
