Abstract
PURPOSE: To recover fine sands certainly without lowering a scraping up capacity while stirring action is continued by providing a precipitation tank in a spiral classifying machine or the like.
CONSTITUTION: A stock material containing fine sands is thrown into a stock material throw-in port A and water is supplied from a water throw-in port B to carry out the water washing and the classifying in a spiral classifying machine 1. Fine sands and mud components in the stock material is sent out from an upper portion of an upwardly floated partition plate 13 into a precipitation tank 5 and precipitated to a bottom of the tank 5. Precipitated fine sands are sent into a spiral classifying machine 1 and floated again upwardly by stirring action and precipitated in the tank 5. By said repeating action, an amount of fine sands sent into a classifying machine 1 is increased and said fine sands can be recovered. On the other hand, water and a mud component are overflowed and flowed externally from a water outflow port 8.
