SCREW AUGER PISTON PRESS Russian patent published in 2022 - IPC B30B11/24 B30B15/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used in molding, lumping of various materials, including those with high viscosity and high humidity. The press granulator contains a housing with a loading hopper in the upper part. A screw auger is coaxially placed inside the housing. A mechanism is connected to the screw auger, made with the possibility of converting the rotational movement of the screw auger shaft into a rotational-translational one. The output of the screw auger shaft has a conical adjustable length limiter of the resulting granules and a removable bushing. The bushing is made in the form of a housing with holes located along its perimeter in the form of longitudinal grooves and an inner part that has a cylindrical surface with a toothed notch up to 50% in length on the screw auger side.

EFFECT: production of briquettes and granules homogeneous in density, strength and mass is ensured.
