摘要

The spreader has a passage (20) to guide and depressurize grits (16), and an adjustable stop (23) to adjust amplitude of displacement of trapdoors (10). A dosing bar (11) extends transversally to the rear of the trapdoors, and mounted movable in a direction perpendicular to a base of a feedhopper or a dump body (3). A control unit of an adjustable hoist (27) displaces the bar to adjust thickness of a stream of grits driven by a roller.
