Abstract
PURPOSE: To improve the classifying performance and recovery rate of a classifier by classifying earth and sand of large sizes by means of an inner drum and classifying earth and sand of small sizes in an outer drum.
CONSTITUTION: The earth and sand sent together with water from a supply trough 7 falls into an inner drum 2 which is rotating as one body with an outer drum 1, and are discharged forward from an earth and sand discharge port 5. On the other hand, ?the turbid water overflowed from the inner drum 2 into the outer drum 1 ?flows up to the overflow port 4 behind, but on the way, the earth and sand of required grain sizes settle down and are sent forward by a spiral 8 for feeding. The mud and impurities overflow to the outside from the overflow port without settling. The earth and soil conveyed by the spiral 8 are conveyed up to near the earth and sand discharge port 3, and are scraped upward by the scraping plate 9 consisting of a porous plate, thence they are discharged forward through the earth and sand discharge port 3 along the conical part on the outside circumference of the inner drum 2.
