Abstract
A screw machine for homogenizing materials of solid, liquid and pasty consistency, said screw machine having at least two engaging screw shafts, each of which is provided with at least one screw section and one core shaft section, on which at least one annular disc whose shape differs from a circular cylinder concentric to the shaft axis is mounted, said annular disc be adapted to be non-rotatably connected to the core shaft section at least against the operational direction of rotation of the screw shaft, and the angular position of said annular disc being adjustable in relation to the core shaft section.
Claims15
Screw machine for homogenizing solid, liquid and viscous material, having at least two screw shafts engaging with one another and rotatable in an operational direction, each of which comprises a screw section, a core shaft section, and an annular disc on said core shaft section, the shape of the annular disc differing from a circular cylinder concentric to the shaft axis, said annular disc being rotatable relative to the core shaft section in at least the operational direction of rotation of the respective screw shaft to adjust the angular position of said annular disc relative to the respective core shaft,
- and means for coupling said annular disc with the core shaft section rotating in said operational direction of rotation,
- said annular discs of the screw shafts engaging with one another and overlapping one another in radial direction, and having peripheral zones of reduced width in the overlapping region.
