摘要： The device consists of the serially connected: vibratory reclaimer and pneumatic classifier (21). The reclaimer has got pipe-cylindrical vertical column (2), ended at the top by the batch tank (3). Inside, there are built up, at intervals, from the top to the bottom: the crusher grid (4), two horizontal sieves: upper (5) and central (6), as well as the lower conical sieve (7). The space of the conical sieve (7) behind the screening side surface is closed off by the bottom ring (8), over which in the side wall there is the pour-out hole (9), led to the transport trough (16). The transport trough (16) is rigidly mounted to the column (2) and rises in spiral fashion along its side surface. At the top end, it is swept externally through the channel (19) led to the feeding screw (20), which through the pour-out is connected to the upper section of the pneumatic cascade classifier (21). Below the conical sieve (7), over the column bottom (11), there is the buffer chamber (10) with the placed crushing-abrasive elements (13) in the form of metal balls. Tangentially to the column (2), below the bottom, there are mounted two generators of vibrations in the form of the rotodynamic motors (14), through their axes of rotation, situated in planes parallel to the column axis and askew to that axis, in perpendicular projection. The transport trough (16) throughout its height is covered externally by the pipe shield (17), which is provided with the connection piece (18), connected with the exhausting installation, preferably, of the cascade classifier (21).
