Apparatus for adjusting the axial position of a rotatable feeder (2) in a charger for sluicing lignocellulose material and, if appropriate, liquid from a first space, with a first pressure, to a second space, with a different pressure, which apparatus (10) comprises an adjustment housing (11) connected immovably to the charger housing and an adjustment shaft (16) which moves the feeder in an axial direction. A worm wheel (23) is arranged on the adjustment shaft, and is coaxial with respect to the same, a shaft for a worm (27) extends through the adjustment housing wall, the worm (27) itself is in engagement with the worm wheel, turning members (29) are arranged to turn the worm and the worm wheel, and means (25, 26) are arranged for converting the rotational movement of the worm wheel, into an axial movement of the adjustment shaft and thus the feeder.
