Abstract: A trough-like vibrating conveyor is used to sort and separate two differently shaped components in a mixture of materials of value. The mixture is separated into generally cylindrically shaped parts, such as hollow parts, and generally flat-shaped parts. The conveyor includes at least two unbalanced motors each arranged on an opposite side of the conveyor extending in the conveying direction. Further, the motors are offset relative to one another in the conveying direction. The vibrating conveyor affords a simple operation for separating the differently shaped components of the mixture as the mixture moves between the inlet and outlet ends of the conveyor and particularly for separating any glass particles. The conveyor requires little in the way of technical or personnel expenditure.

Abstract: For the rapid replacement of an outlet grate in a crushing machine and for adapting the crushing operation to different types of materials, an outlet grate is located within the crushing machine housing extending generally horizontally between a pair of opposite walls. An opening is provided in at least one of the opposite walls in the region of the grate and the grate can be removed in whole or in part through the opening.
