<p>PROBLEM TO BE SOLVED: To improve the rate of recycling operation by providing a liquid gravity separator suitably adapted to the fraction of general waste matter plastics. SOLUTION: This apparatus comprises a means for crushing 12 and classifying 13 on material consisting principally of plastics of two or more kinds of different gravities in predetermined grain ranges, a first gravity separation means 18 for conveying plastics and making rough separation per kinds of material through gravity difference, a second gravity separation means 22 for separating lightweight side plastics separated by the first gravity separation means per kinds of material utilizing gravity difference again, means 23, 24 for separating the plastics fractionated separated per kinds of material and medium liquid, and a means 27 for permitting the liquid medium to be circulated to blending means 15, 19.</p> |
