Abstract: A dosing system for loose compressible material having heterogeneous granulometry and/or density and outputting the material though a main outlet is disclosed. The dosing system comprises a receiving structure for receiving the material to be dosed. A homogenizing system closes the receiving structure outlet and normalizes the material. A first conveying system acts as a base for the receiving structure, and transports the material towards the homogenizing system. A leveling adjustment system downstream of the homogenizing system levels the homogenized material. A second conveying system receives material from the homogenizing system and transports the material beyond the leveling adjustment system towards the main outlet. The homogenizing system, the leveling adjustment system and the second conveying system define a transition volume in which the material travels between the homogenizing system and the second conveying system. A method for dosing such a material is also disclosed.

Abstract: A mobile screening unit for screening bulk material. The screening unit comprises a first screener, a second screener, and an elongated mobile support frame having a longitudinal axis. The first screener is mounted to the support frame and extends longitudinally thereon. The first screener has an inlet for receiving the bulk material containing large-sized, medium-sized, and small-sized particles. The first screener also has a first outlet for releasing large-sized particles and a second outlet for releasing medium-sized and small-sized particles. The first screener is used for screening the bulk material along a first direction substantially parallel to the longitudinal axis of the support frame. The second screener is mounted to the support frame and extends longitudinally thereon.
