The effective areas of outlet ports of a hopper 2 of a centrifugal distributer are adjusted by moving an annulus 9, containing the ports, in one direction and a masking member 11, provided with masking plates 12, in the opposite direction, by means of a lever 15 which is mounted on a support 21 which is slidably adjustable on a holder 22 and held in the adjusted position by a pin 22. By moving the support 21 the annulus 9 and the masking member 11 are radially adjusted about the axis 7 without altering their relative positions. |
