<p>PARTICLE CLASSIFIER A device for simultaneously fragmenting cohesively bonded particles into particles, by the action of a turbulent air stream, and classifying the particles according to their size, the device has a horizontal hood connected to upstream and downstream air ducts. Equipped with an air fan, the upstream air duct has a converging section to acelerate a stream of air. Feed hoppers distribute the cohesively bonded particles into the upstream end of the hood where they are fragmented into particles and the particles classified. Collecting devices are below the hood to receive the classified particles. A recirculating air duct is disclosed including a built-in filter device. A method is also disclosed for simultaneously fragmenting cohesively bonded particles into particles and classifying the particles according to their size.</p> |
