Abstract

A system and method for recycling a waste glass cullet includes a first screening station for separating large glass shards of approximately one inch in diameter from smaller glass shards in the cullet, a crusher to reduce the large glass shards to smaller glass shards smaller than approximately one inch in diameter, a second screening station to separate remaining large contaminants having a diameter of approximately one inch or greater from the cullet, a series of vacuum inlets disposed along a conveyor to remove light contaminants, a presoaking apparatus comprising a holding tank partly filled with a presoaking solution, a rotary washing apparatus comprising a drum with vanes disposed along an inner wall of the drum to toss the cullet in the washing solution, the vanes being oriented so that the cullet is tossed progressively forwardly toward a discharge outlet of the drum, to remove buoyant contaminants from the cullet, a dewatering apparatus to remove excess water from the cullet, and a dryer for reducing the moisture content of the cullet. The system and method may further include a second rotary crusher for reducing the cullet size to 12 mesh or smaller and a vibratory multi-deck screen to separate the crushed glass cullet into specified particle sizes. In the preferred embodiment the rotary drum washer for includes a rotating drum having one or more vanes disposed along an inner wall of the drum to toss the cullet in the washing solution, the vanes being oriented so that the cullet is tossed progressively forwardly toward a discharge outlet of the drum.
