Washing=out device for residual material such as concrete

摘要

The washing-out device has at least two filling containers (10, 10') with water input, from which long narrow conveyor casings (13, 13') are angled upwards to ejection apertures for the coarse residue. Each has a single motor-driven screw conveyor (18, 18') with turning axis parallel to the longitudinal axis of its conveyor casing, through the filling containers and conveyor casings at least as far as the ejection apertures. Each filling container has a feed device (30, 30', 31, 31') feeding the residual material to the side of the screw conveyors.
