Abstract

Silo à fond conique du genre de ceux utilisés pour les matériaux plastiques en morceaux de petites dimensions, de faible densité et présentant des valeurs élevées de l'humidité et des propriétés collantes et életrostatiques. Il comporte une hélice conique coaxiale dans le fond conique, un orifice de sortie au bas de ce fond conique, et une hélice cylindrique débitrice sous ledit orifice de sortie. Le dispositif peut être utilisé pour obtenir des débits de doses constantes et aussi pour effectuer éventuellement, au préalable, le mélange de matières différentes.Silo with conical bottom of the kind used for plastic materials in pieces of small dimensions, low density and having high values of humidity and sticky and electrostatic properties. It comprises a conical helix coaxial in the conical bottom, an outlet orifice at the bottom of this conical bottom, and a cylindrical supply helix under said outlet orifice. The device can be used to obtain constant dose rates and also to optionally perform the mixing of different materials beforehand.
