Apparatus and method are disclosed for separating and recovering the solid particle components of a waste aggregate using screening and air separation mechanisms. Such an aggregate could be log yard waste comprising soil, wood and mineral particles. The aggregate is first mechanically screened to produce a product of fine particles (the soil) and a plurality of sized streams, each comprised of similarly sized particles of different densities (the wood and mineral particles). The sized streams are then separately but simultaneously introduced into an air separation device which comprises an upstanding funnel-like member forming an upwardly converging passage through which air is flowing. The smallest sized stream of particles is fed into the passage at the lowest elevation, where a separation of light and heavier density particles occurs, light particles moving upwards with the air, heavier falling downwards. Medium and larger sized streams are fed at respectively higher elevations, where the air velocities are respectively higher, separation again occurring. The inlet point for each stream entering the converging passage is selected to match the air velocity at that point with the desired separation result: heavier density particles to drop, lighter density particles to rise. Two products are recovered from the funnel-like member, a high density product (the mineral particles) of varying particle size from the base of the passage and a low density product (the wood particles) of varying particle size from the top.

Mechanical screening apparatus for separating three components of a particular aggregate having a fine first component, second and third components of different density having particles of varying size, and oversize, comprising: a linear array of disc screening means for classifying particles by size, said means having sequential sizing sections, including a first sizing section, for advancing the aggregate therealong and screening it to separate the particles into progressively larger particle fractions and residue aggregate; a cylindrical, rotatable trommel, extending along and encompassing the first sizing section, for receiving and screening the fraction passed by said section to produce a first product consisting essentially of the first component and a sized stream of oversize; a plurality of longitudinally staggered and verticalled spaced conveying means, one positioned under each of the remaining sizing sections, for receiving the fraction produced from that sizing section and conveying it for further treatment.
