Abstract
A method for screening of wooden chips and the similar stuff placed upon a vibrating conveyor including a chute (1) and a frame (2), at which the bottom (4) of the chute (1) is provided with a screening grid consisting of mutually parallel screening rods (6) and is brought to vibrate relative to the frame (2) by help of a vibrating device (11) and at which the frame (2) is provided with longish carriers (9) which are arranged projecting up between the screening rods (6) and the carriers (9), and at which the carriers (9) is brought to vibrate partly relative to the frame (2) and partly relative to the chute (1) with the screening rods. The chute (1) with the screening rods (6) is vibrating in the same plane as the carriers (9) at which the relative movement between the screening rods (6) and the carriers (9) is controlled by a mutual phase displacement of these respectively movement of vibration. The invention also includes a screen for carrying out the method at which the carriers are movable arranged on the frame (2) and connected to a vibrating device (10).
