Abstract
A device for spreading granular and/or powdery material comprising a hopper for material to be supported and at least two distributing members rotated in opposite directions about vertical rotary axes, material feeding means provided between the hopper and distributing members for feeding material from the hopper to the distributing members so that each of the two distributing members receives the material eccentrically with respect to its rotary axis; the distributing members having such shape and being drivable in a manner, and the feeding means being constructed and disposed whereby in operation material is supplied to the distributing members so that each spreads material across a sector which substantially coincides with the sector across which the other distributing member spreads material. With such a device the material is advantageously spread uniformly and different materials may be spread in the same manner without the need for readjusting various members of the device.
