Abstract
An improved article separator in which the particles are separated through the use of an vertical air-flow permitting heavier particles to fall while entraining the lighter particles and storing them in a hopper. The air flow is automatically controlled using a microprocessor or similar apparatus which checks the air-flow/speed within the vertical channel or tubing. Using this data, the controller adjusts a dampener at the end of the channel. The dampener, restricts the flow of air through it so that the overall air-flow within the channel is adjusted. Using a dust collector to create the air-flow, a plurality of vertical columns are used to separate varying sizes of particles. In this manner, the debris is simply swept or shoveled into a hopper and the particles are automatically separated.
