Conveyer furnished with a screen, where the conveyor includes a chute (1) designed to vibrate relative to a foundation (2) and by that transport material.According to the invention, there is at least along a section of screen (1) a number of similarly mounted parallel rods (21) and between each one of these an upright band-iron (18). Columns (23) with a certain breadth are trained between each rod (21) and nearby band-iron (18). The rods (21) are fixed to the screen (1) while the band-iron is fastened relative to the foundation (2).Through this the rods (21) will vibrate while the band-iron (18) remains still, whereby the material fractions at a size the same as or smaller than the width of the rods (23), effectively passes through the rods (23).<IMAGE> |
