A device for impact breaking up of compressed material packed in a sack includes a frame and means to support a driving and vibrating assembly of the device. A vibrating element or tunnel is inclined and is formed by the joining of two rigid bodies having concave U-shaped cross sections, the respective concavities of the bodies being face to face and having therebetween interchangeable vibration absorbing separators. The upper body has a shorter length and has, at one of its ends, a roller which may turn freely and whose height may be regulated, while the lower body has, on its wide external face, suitable supports for the vibrating assembly. The vibrating and supporting means of the vibrating assembly are elastic bodies arranged in pairs. |
