Abstract: A device to distribute solids such as seeds, fertilizers, salts, or other granular materials through a machine for agricultural use or other similar uses, of the type that uses horizontal rotating plates or discs with spreader pallets, wherein access of the material to be distributed to the spreader pallets is tangential thereto, by use of a channeller downloaded in the central area of the disc. The device does not break the particles to be spread and, thereby, they maintain their original mass, which let us affirm that the working area is extended and the uniformity of the distribution is improved. Additionally, the tangential access of the material from the center of the rotating plate or disc, and with the same course of the pallets, gives an additional speed to the particles that allows to further increase the working area.
