Device for introduction of materials in a rotating drum of a mixing plant for the production of bituminous materials

摘要

The device has a belt-loader conveyor (20) comprising upper and lower deviators (25, 30) at its end located at an inlet (12) of a rotating dryer-mixer drum (10) and arranged both sides of the conveyor. The deviators are pivotally movable between a position away from each other liberating an end of the conveyor to launch materials to interior of an envelope (11) and another position in prolonging each other with respect to the end of the conveyor to deviate the materials to an evacuation tube (19) outside of the drum.
