Abstract: An apparatus for distributing particulate material on a conveyor movable along a respective operating direction includes: a tank containing particulate material and equipped with feed means for feeding the particulate material; and distribution means located downstream of the tank to receive the particulate material and the particulate material on the conveyor. The distribution means include a diffuser element and a vibrating device to shake the diffuser element. The diffuser element extends with its sliding plane along its axis between an infeed portion to receive a preset flow quantity “Q” of particulate material, and an outfeed portion. The diffuser element includes a transversal partition at a predetermined distance from the sliding plane to form a neck which acts in combination with a vibration imparted by the vibrating device to distribute the particulate material along a predetermined width of the outfeed portion.
