Abstract
A system and method for sorting demolition debris into preselected groups, wherein the system comprises an initial screen for sorting out fine particulate material, a floatation tank for sorting the debris into floatable material and heavy material, a heavy material conveyor for removing the heavy material from the floatation tank, a magnetic conveyor for removing the ferrous metals from the heavy material conveyor, and a hand-sorting conveyor whereby various construction items are removed from the debris so that all that remains is pure concrete and brick debris.
