The invention relates to a rock processing plant () having a machine frame (), which supports a screening unit (), wherein the screening unit () has at least two screen decks (), which are arranged offset from each other in the vertical direction (H) of the rock processing plant (), wherein the screen decks () each have a discharge area (AA), wherein a transport device () is connected to the screening unit () in the conveying direction, wherein the transport device () has a feed area () and a discharge area (), wherein a transport means, in particular an endless circulating conveyor belt (), extends in a transport direction (D) at least partially between the feed area () and the discharge area (), wherein the transport device () is attached to the machine frame () by means of a mechanical actuator (), wherein the mechanical actuator () can be used to move the feed area () of the transport device () between two control positions, in which the feed area () is optionally assigned to one of the discharge areas (AA) of the two screen decks () or both discharge areas (AA), and wherein the mechanical actuator () can be used to move the feed area () of the transport device () between the two control positions in the vertical direction and in the transport direction (D) of the transport device (). Such a rock processing plant has a simple and space-saving design, which permits a conversion to the different operating positions with little effort.

Rock processing plant

A belt tensioning device for a crusher or a screening machine for tensioning at least one circulating drive belt which is deflected about a belt pulley of a drive and has a load strand and an empty strand. The drive can be driven with a crushing assembly, a screening unit, a generator, or the like of the crusher by the drive belt. The vibrational stress acting on the machine chassis can be significantly reduced in that the belt tensioning device has two tensioning rollers each of which is rotatably mounted on a holder of a tensioning part. One tensioning roller is paired with the empty strand and the other is paired with the load strand. Additionally, the two tensioning parts can be adjusted relative to each other between an open position and a tensioning position, in which the tensioning parts are held against each other at least opposite the tensioning direction. In particular the tensioning parts can be blocked against each other, and the complete closed system can be freely moved linearly using adjustment guides according to the load situation.
