Spreading device for granular or powder material

摘要

The spreader has stripping units with a cleaning roller (5) placed in an alveolar roller, where the roller (5) has an axle (B) parallel to an axle (A) of the latter roller. The roller (5) has radial blades (51) with dimensions adapted such that outer edges of the blades engage in cells (34) when the alveolar roller is driven in rotation to push a granular/powdery material (9) contained in the cells out of the alveolar roller.
