rock seprators for science

Design and testing of a rock separator for sortyard debris.

A precommercial prototype of a rock separator for timber yard debris was designed, built and field tested. Rock separation efficiencies of up to 90% were achieved at a processing rate of 8.8 t/h. Changes in rubber conveyor belt speed and tilt angle were found to be more effective than changes in slope angle to increase the rock separation rate.
