Abstract: The present invention concerns a device (1) for the transport and compaction of material, preferably of combustible material destined to the feed of plants for energy production. The device includes a pressing belt (2) overlapped to a conveyor belt (3) according to a certain angle of incidence in such a way as to define such a convergent advancement path (4) as to compact the material during its advancing motion. A first (9) and a second (10) bulkhead are arranged in such a way as to contain into the advancement path (4) the material comprised between the belts. In accordance with the invention, the first bulkhead (9) and the second bulkhead (10) result to be mobile integrally at least with respect to the conveyor belt (3) and arranged at such a reciprocal distance d that the superior belt (2) results to be insertable into the space (11) comprised between the bulkheads (9, 10) in such a way as to compact the material contained into the space (11).
