<p>The flow of material to be treated undergoes three successive phases of treatment: a "launch" phase, with a cosequent impact against a wall, during wich the dynamics of impact differ according to the rigidity of the material; a second phase in which an appropriately regulated current of air passes across the trajectory of fall; and a third phase in which, by means of an inclined plane moving in a predetermined direction, the material falling from above it in the aforesaid different trajectories acquires, in part through friction, different speeds and directions of motion. The mchine for implementation of the above procedure has : a device (3) to launch the flow of arriving material to be separated; a wall (4), variabmy inclinable, against wich the material launched by device (3) strikes; an outlet (7) for a flow of air that invests the material (3) after its impact against wall (4); an inclinable plane (10), with the possibility of varying the angle of inclination and the velocity</p> |
