The invention relates to a device for sorting out coins (02), in particular elongated parts (06) and/or copper mesh (07), from a bulk of metal, in particular a bulk of heavy metal and/or NE metal, comprising at least one sorting gap (04) for coins (02), each gap being delimited by at least two rollers. The rollers can be rotated about a rotational axis (A) by means of a drive (13) such that objects which cannot be conveyed through the sorting gap (04), in particular NE metal objects or heavy-metal objects, are forced away from the sorting gap (04) either in a direction along the rotational axes (A) or in a direction perpendicular to the rotational axes (A). According to the invention, the rollers are designed as brush rollers (01), and each brush roller has brushes with at least two different lengths. The bulk of metal is supplied to the brush rollers (01) by a supply device (05) such that the bulk of metal is deposited on the brush rollers (01) at least partly in the longitudinal direction of the rotational axes (A) and/or at least partly perpendicularly to a plane formed by the rotational axes (A).

A disc screen for separating solid residues which comprises multiple parallel rotation shafts, each of which carrying, fixed thereto, a plurality of discs. The lateral faces of the aforesaid discs are provided with thrust wings having curved section, which are adapted to intercept components of the material to be screened, in particular light or filamentous materials, in order to expel them outside the interspaces between the discs, so as to prevent possible tangling and obstruction of such materials at the rotation shafts.

The present invention relates to a screening apparatus (100) comprising a frame (10); a feed conveyor (20) mounted at one end of the frame and a screen (30) for accepting waste material from the feed conveyor, the waste material comprising fines and oversize material. The screen (30) is mounted on the frame (10) about a pivot axis and comprises a trough (32) with a top opening; and a plurality of driven elongate rotating members (40) disposed in an arc along one side of the trough and along at least a portion of the base of the trough (32) for causing circular or helical flow of the waste material within the trough. The trough (32) further comprises a base opening for discharging the fines material and an oversize material outlet for discharging the oversize material; and wherein the screen is mounted on the frame such that the elongate rotating members (40) are each independently perpendicular to the pivot axis.

A screen according to the invention comprises replaceable screen modules A screen module are detachable from the screen as well as replaceable and attachable to the screen. According to an aspect of the invention, the screen comprises a frame and one or more screen modules which are detachable from the frame of the screen, attachable to the frame of the screen, and/or replaceable.

Disc screen for separating solid residues, which includes multiple parallel rotation shafts, each of which carries a plurality of discs fixed thereto. In addition, the disc screen includes multiple shaped rings, which are each constituted by multiple sectors removably mounted around the rotation shafts, and they are placed between the discs in order to simply and easily vary the screening section. The external edge of each shaped ring is provided with thrust sections, which are adapted to intercept the material to be screened in order to subject the latter to a greater stress, which facilitates a more efficient separation of the materials, and push upward components of light and filamentous material so as to prevent possible entangling and obstructions of such materials at the rotation shafts.
