ABSTRACT:
This invention relates to a method and an apparatus for controlling the speed and/or direction of movement (A, B) of a screw discharger (1, 11, 101, 201). According to the invention, the bending load on the screw (2, 12, 102, 202) of the screw discharger is measured by means of one or more transducers (112, 212) which generate a loading signal on the basis of which the drive system (110, 210) controlling the speed and/or direction of movement (A, B) of the screw discharger (1, 11, 101, 201) is controlled.
