Abstract: The invention relates to a system for the gravimetric sorting of a mixture of substances during the processing and/or the recycling of residual building materials and/or demolition materials, comprising a fractioning unit (2) adapted to divide the mixture of substances into at least m fractions (A, B, C); at least n·m gravimetric densimetric tables (A.1, A.2.2, A.3.2), arranged in m cascades each with at least n densimetric tables distributed to n stages, wherein the fractioning unit is coupled to them densimetric tables (A.1) of the first stage such that a different one of the at least m fractions can be supplied to each of the densimetric tables of the first stage; wherein, within each cascade, each densimetric table of a considered stage (A.2.2, A.3.2) is coupled to a densimetric table (A.1, A.2.2) of the preceding stage such that either the first partial fraction or the second partial fraction (12, 22) of the densimetric table (A.1, A.2.

Abstract: A rotary cooler is provided, consisting of a plurality of transport tubes for transporting material to be cooled, wherein the plurality of transport tubes are arranged about an axis of rotation and are adapted to be filled jointly via a filling region with material to be cooled, characterized in that each transport tube is arranged substantially concentrically in a cooling tube in which a cooling medium flows and cools the material to be cooled via the wall of the transport tube. Furthermore, a method for operating said rotary cooler is provided.

Abstract: A method for recording motion patterns (210) of tumbler screening machines (410) is disclosed, wherein the method comprises applying of an active or passive optical marking (500, 510) at a tumbler screening machine (410), recording an image of the optical marking (500, 510) during operation of the tumbler screening machine (410), establishing image data for a motion curve (200), and internally or externally evaluating the recorded image data and determining machine parameters and diagnosis data. Furthermore, a device for recording motion patterns (210) of tumbler screening machines (410) is introduced.
