Twin Screw Extruder Gearbox

Twin Screw Extruder Gearbox

The SZ series double-screw extruder gearbox is a specialized mechanical drive system designed to complement conical double-screw extruders. This gearbox reduces the speed and amplifies the torque from the main motor before transferring it to the long shaft of the distribution box. The long shaft drives the short shaft through a pair of slender conical screw gears with a 1:1 drive ratio. Both the long and short shafts operate the screws at identical angles, facilitating outward rotation in opposite directions to ensure the production of high-quality extruded products.
