<p>The device (1) has a conveyor belt (3) extended in a direction of a downstream breast roller (12) arranged in bottom of an active cylindrical envelope (5). The conveyor belt defines an angle equal to 45 degrees between the cylindrical envelope and the breast roller with respect to a horizontal direction. Detection units (13) are provided for presenting particles (2) on the conveyor belt in downstream of the cylindrical envelope with detector for controlling a pneumatic and/or hydraulic and/or mechanical type detected particles selecting unit (14).</p> |
