DEVICE AND METHOD FOR SEPARATING MATERIALS OF DIFFERENT FLOWABILITY THAT ARE MIXED TOGETHER

摘要

The invention relates to a device (10) for separating materials of different flowability that are mixed together, comprising a frame structure (11), a hollow drum (12) which is driven in rotation and is mounted on the frame structure (11) and has a perforated lateral surface (M), an endless compression belt (13) which can be pressed from outside against the hollow drum while being wrapped around part of the circumference of the hollow drum and which is driven in a circulating manner, a product drawing-in wedge (14) which is formed by the compression belt and the hollow drum for guiding into the device a product flow, consisting of compression material, between the hollow drum (12) and the compression belt (13) in an entry region (E) of the product flow, and a support device (15) for the compression belt (13) with at least one support element (16) which is arranged on the opposite side of the compression belt (13) from the hollow drum (12), wherein the support element (16) is designed as a roller track (17) comprising multiple rollers (18) that are arranged one behind the other in the conveying direction (F) of the product flow and are mounted at least in part in a resilient manner, the device being characterized in that the spring force at least of individual rollers (18) can be controlled. The invention further relates to a corresponding method.
