Mixed solid waste, such particularly as municipal waste, is subjected to treatment which separates the majority of the ferrous metal pieces from the other solids, and the invention provides apparatus for separating the resulting mass into (a) flat-shaped pieces (b) chunky-shaped pieces, and (c) long thin or otherwise oversized pieces by causing all the pieces to advance along a moving conveyor surface through successive stations at which openings of predetermined size and shape accept pieces of the (a) and (b) shapes, having only the (c) category on the conveyor.

Apparatus for use in the processing of scrap to separate essentially flat-shaped pieces of a predetermined maximum dimension from a mass of pieces also including thin shapes of a greater maximum dimension and chunky shapes, comprising: (a) conveyor means including a surface defining an extended path

Apparatus for use in the processing of scrap to separate essentially flat-shaped pieces of a predetermined maximum dimension from a mass of pieces also including thin shapes of a greater maximum dimension and chunky shapes, comprising: (a) conveyor means including a surface defining an extended path and means for effecting movement of said surface causing said mass to travel along said path with respect to said surface, (b) a portion of said surface being provided with a plurality of generally rectangular openings arranged in spaced relation both lengthwise and cross-wise of said surface and with the upstream and down-stream edges thereof respectively substantially perpendicular to the length of said path and spaced from each other by a distance substantially equal to one-half said predetermined maximum dimension, (c) each of said openings having a bottom wall which is stationary with respect to said surface and is inclined downwardly from the downstream edge thereof at a relatively small angle away from the direction of travel of said mass to define a slot-shaped hole between the lower edge of said wall and the upstream edge of said opening, (d) whereby as a flat-shaped piece whose dimension along said path is less than twice the corresponding dimension of said opening travels across said opening, it will tilt backward when the trailing end thereof clears said upstream edge of said opening and slide down said bottom wall to said hole in the reverse direction from the travel of said mass.
