ABSTRACT:
Wood is reclaimed from demolition debris in a process that includes a vibratory feeder 12 feeding material to a hammer mill 16 which comminutes the debris into fragments that are then fed to a disk screen 22. Debris fragments below a predetermined size are fed to a trommel 28. The trommel sorts small debris particles under a second smaller predetermined size, directing smaller particles to a first waste conveyor. Intermediately sized debris fragments between the first and second predetermined size pass through the outlet of the trommel to a sink float tank 48 in which the non-wood waste debris fragments that sink are transported away by a second waste conveyor 52 and floating wood debris fragments are recovered out of the tank 48 by conveyor 50.
