Abstract

A sorter for reclaiming particles, such as glass particles, of a predetermined color or transmissivity utilizes a belt conveyor having a longitudinal row of openings over which particles are positioned for being conveyed past a light source and light sensor on opposite sides of the belt to sense the transmissivity, or color of the particles. Glass particles having a predetermined transmissivity are separated by suitable facilities, such as an air jet directed through the openings in the belt.
