Abstract
A method of breaking up and separating waste glass with use of a lattice 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, the diagonal dimension of the openings of the lattice being smaller than the maximum width of projection of planar extraneous matter, the method being characterized by dropping the waste glass onto the grizzly surface of the lattice to break up the waste glass under gravity and to separate the waste glass into an undersize portion passing through the lattice and an oversize portion, and repeatedly subjecting the oversize portion to the aforesaid operation to obtain cullet as an undersize material and to remove the extraneous matter from the waste glass as an oversize material. 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 lifter 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.
