A machine for mixing loose materials such as animal feedstuffs and distributing the mixed product comprises a rotary drum 4 open at one end 4a and mounted on a frame which can be self propelled or drawn as a trailer. The drum 4 is generally cylindrical, and is rotatable about an axis x inclined downwardly at a shallow angle from an open end 4a. Inwardly from the inside of the walls of the drum project helical mixing blades 25 and centrally through the drum extends a coaxial shaft 60 with a surrounding helical screw 61 which can be held fixed with respect to the frame as the drum rotates, to promote mixing, or, allowed to rotate with the drum to promote discharge of mixed material from the drum. The materials to be mixed are fed to and discharged from the open end 4a by way of a screw conveyor 12, 18. <IMAGE> |
