Device inter alia for uniformly distributing solid and/or liquid particles, and an assembly comprising such a device

A device inter alia for uniformly distributing solid and/or liquid particles, characterised in that it comprises, on the one hand, a hollow vertical primary shaft (1) driven in rotation, the bottom end comprising a substantially horizontal primary ring (4) the bottom surface of which bears vertical teeth (5) disposed in concentric circles, the device on the other hand comprising a hollow vertical secondary shaft (2) in which the primary shaft (1) is coaxially disposed and which is driven in rotation in the opposite direction to the rotation of the primary shaft (1), the bottom end of the secondary shaft comprising a cylindrical cage (10) containing a secondary ring (11) secured to the aforementioned bottom end and wider than the primary ring (4) and a disc (12) connected to the bottom surface of the secondary ring (11) by at least three bars (13), the top surface of the disc (12), which faces the bottom surface of the secondary ring (11), comprising on the one hand vertical teeth (14) disposed concentrically and staggered with respect to the teeth (5) on the first ring (4) disposed inside the cylindrical cage (10), and on the other hand comprising a central circular anvil (15) coaxial therewith and at least equal in diameter to the primary shaft (1).
