CONSTRUCTION WASTE APPLICATIONS Construction waste consisting of wood, plastics, metals and mineral materials Best Solution. Smart Recycling. doppstadt.com
Process description The process of treating construction waste consists of a screening machine, wind sifter, sink float separation and water treatment. The screening machine serves to separate the fine particle fraction and thereby reduces the amount of sludge. The oversize is further separated by density. Firstly, foils are removed with the help of a wind sifter. These can then be burned for energy. The heavy fraction is transferred from the wind sifter to the sink float separation system, where it undergoes further density separation using the density of water. The heavy stones and metal parts are discharged and can be further separated by magnets. The light pieces of wood and plastic are washed again and can then be burned for energy in a si- milar way to the foil fraction. For the continuous operation of the sink float separation system, a lamella separator is needed to treat the water. Settleable solids sediment here without the need for a settling tank that would take up a lot of space. THIS IS DOPPSTADT Construction waste cannot be dumped because of its organic components.

OW SPEED HREDDER OF OVERVIEW CONSTRUCTION WASTE STONES/ EDING EM IPSUM R SIT AMET Water treatment guarantees continuous operation and consistent separation. Depending on the material, a dosing station may also be necessary along with the lamella separator. ROW The foils are separated from the heavy fraction and are taken to a container or discharge conveyor. The heavy fraction is handed over to the HDS-M via the side conveyor to undergo sink float separation. FINE FRACTION WOOD/PLASTICS LASTIC ARATOR DIAGRAM FOILS DER SINK FLOAT The HDS-M separates the stones from the wood by density. Additionally, the wood fraction is cleaned of surface contaminants, for instance sand, in a washing drum. SCREENING The fine fraction is first screened to prevent too much dust forming in the wind sifter and too much sludge in the HDS-M. OVERVIEW
