Abstract (en)
When classifying heterogeneous solids by passing them over a disc screen (4) formed by a number of rollers (6) rotating about parallel axes disposed in a common horizontal plane there is a tendency for smaller solids to rest on top of larger solids during their passage across the screen. However this difficulty is mitigated by providing a second disc screen (5) below the first so that the solids tumble from the upper screen (4) onto the lower screen (5).
