Useful fraction separation device for upholstered furniture in the involves stages of mechanical comminution and separation into fractions

摘要

The separation device involves mechanically comminuting the furniture into a material mixture of particle size 60-100 mm and then to a particle size of less than 40 mm. The mixture is separated into light and heavy fractions in an air classifier (13). The light fraction is discharged, and heavy fraction is separated by a sieve (10) into coarse wood fractions, from which ferrous and nonferrous metals are separated out and biogenetic fuels with 5-10% contamination are removed.
