Abstract
Refuse, waste material is loaded first into a shredder, the output of which is passed through a ferrous metal detector and then a non-ferrous metal detector, thereby removing most of the metal materials. The partially treated waste product is then fed into a separator tank at least partially filled with water, and made turbulent by the introduction of pressurized water and pressurized air to separate floatable materials from the non-floatable, heavy material such as concrete. The output of the separator tank, after separating the floatable materials, is then fed through a settlement tank, removing the remaining heavy slurry materials from the remaining lighter slurry of the waste material. As an option, the remaining lighter slurry waste material can be fed back into the separator tank for further processing.
