Abstract
PURPOSE: To remove adhered substances of gravel and sand as well as to collect said gravel and sand in a uniform particle size condition by a method wherein air is injected into water containing gravel and sand to discharge an overflowed component and gravel and sand is conveyed out.
CONSTITUTION: Air is injected into water containing gravel and sand received in a main frame 3 from an air injecting pipe 5 to remove mud or impurities adhered to gravel and sand. At the same time, a light wt. component overflowed from the main frame 3 by float action is discharged from a discharge pot 7 and, on the other hand, gravel and sand fallen by gravity is conveyed out above the water level by a conveyor apparatus 13. As described above, substances mixed in or adhered to gravel and sand are removed and classification is carried out.
