摘要
A system for sorting a mixed stream of different colored cullet into separate groups of same colored cullet comprises a light emitting source for transmitting light, such as white light, through a cullet, and a camera having a plurality of pixels for receiving light transmitted through the cullet or detecting the absence of light blocked by an opaque contaminant, the camera providing at least one value from the light received, wherein the cullet moves along a designated path based on the at least one value. The camera collects the received light at a desired sampling interval and a circuit converts the values into digital representation values. The circuit calculates a non-linear function from the digital representation values. An electrostatic or fluid driving actuator directs the cullet along a deflected path based on a value of the non-linear function. A vibratory feeder provides the cullet onto a conveyer belt having an exit roller of a desired diameter.
