Patent ID: 11305317

Abstract:
The invention relates to a rock processing plant (10) having a machine frame (13), which supports a screening unit (20), wherein the screening unit (20) has at least two screen decks (21, 22), which are arranged offset from each other in the vertical direction (H) of the rock processing plant (10), wherein the screen decks (21, 22) each have a discharge area (A1, A2), wherein a transport device (15) is connected to the screening unit (22) in the conveying direction, wherein the transport device (15) has a feed area (15.1) and a discharge area (15.2), wherein a transport means, in particular an endless circulating conveyor belt (15.3), extends in a transport direction (D) at least partially between the feed area (15.1) and the discharge area (15.2), wherein the transport device (15) is attached to the machine frame (13) by means of a mechanical actuator (31), wherein the mechanical actuator (31) can be used to move the feed area (15.1) of the transport device (15) between two control positions, in which the feed area (15.1) is optionally assigned to one of the discharge areas (A1, A2) of the two screen decks (21, 22) or both discharge areas (A1, A2), and wherein the mechanical actuator (31) can be used to move the feed area (15.1) of the transport device (15) between the two control positions in the vertical direction and in the transport direction (D) of the transport device (15). Such a rock processing plant has a simple and space-saving design, which permits a conversion to the different operating positions with little effort.
