INSTALLATION FOR CONTINUOUSLY SEPARATING BULK MATERIALS LARGER THAN WATER AND BULK MATERIALS WITH LESS DENSITY THAN WATER OR NEIGHBORHOOD THEREOF

摘要

An apparatus comprising endless conveying means (5) arranged in a vessel (2) beneath inlet means (4, 9), and means (7, 23) for injecting pressurised air under the conveying means (5) at least in the area directly beneath the inlet means (4, 9). The conveying means (5) are designed in such a way that the material-supporting surface (8) thereof lets the pressurised air through while retaining and thus conveying the heavier-than-water materials.
