A retruder having a housing with a pair of counter-rotating worm gears axially mounted within said housing for counter-rotation to process a medium. The housing has an inlet and also an outlet through which the processed medium is discharged which is transverse to (radially of) the housing axis. An insert in the housing is selectively slidably movable along the housing axis to overlie the outlet to adjust its size. |
