ABSTRACT:
Water is supplied to an inclined drum having a helical wall on its inner peripheral surface to cause the water to flow over the helical wall and also on the inner peripheral surface of the drum and to thereby form a flow of water running from the upper end of the drum to its lower end. Waste glass is fed to the drum while the drum is rotated at a high speed. During falling of the waste glass onto the flow of water, during settling of the waste glass in the water flow while it is being sent toward the drum upper end by the helical wall, and while the settled waste glass is maintained by the high-speed rotation of the drum in a suspension-resembling state in which pieces of the waste glass are dispersible and in rocking motion circumferentially of the drum, extraneous matter is forced toward the drum lower end and run off therefrom due to its resistance per unit weight thereof to the flow of water which resistance is greater than that of the waste glass. The waste glass separated from the extraneous matter is discharged from the drum upper end. An apparatus comprises the above-mentioned drum rotatable at a high speed, means for supplying water and means for feeding waste glass. The helical wall of the drum has a height and a pitch which are suitable for producing the flow of water.
