Title: Treatment of mixed municipal and commercial waste
Inventor: NEU WERNER DR ING
IPC: B07B9/00
Filed: 1997-11-22
Abstract: The mixture is spread out over an area separating and gathering (5) it into distinct fractions. These are agitated and vibrated over a series of screening grids (11). The spread mixture is simultaneously classified by an upward current of air induced by a blower (7), which is deflected to the side, to a settling zone. Heavy material carried over the last screen is carried off; that falling through, continues to further stages of separation. An Independent claim is included for the corresponding plant. Preferred features: The strength and/or velocity of the airflow through the grid is increased from place to place. The waste is initially comminuted, shredded or torn to smaller pieces. In this process, fines are screened off. A screening drum is used for initial treatment, which includes spiral cutters (16), both reducing the mixture and screening the fines. Oversize passes to the vibratory screening grids, for treatment as described.
