Abstract
An apparatus for breaking up and separating waste glass to obtain cullet comprising a grizzly made up of parallel bars arranged at a spacing smaller than the minimum width of projection of three-dimensional extraneous matter and auxiliary parallel bars disposed over one surface of the grizzly and arranged at right angles to the bars to form a lattice, the diagonal dimension of the openings of the lattice being smaller than the maximum width of projection of planar extraneous matter. The lattice is in the form of a rotatable drum with the grizzly positioned on the inner side of the its peripheral portion. The drum-shaped lattice has scraper plates attached to its inner periphery and an inlet for the waste glass and an outlet for the extraneous matter at its opposite ends respectively. The parallel bars can be arranged either annularly or axially with the auxiliary parallel bars being arranged oppositely.
