Abstract
The invention concerns a spiral module (1) for a trommel screen comprising a flat part (5) that transports ore and that is designed as a product that becomes worn, with an elastic cladding (27) that functions as wear lining, intended to interact with the charge for the transport of the charge forwards on a sieving deck (2) that is a component of the sieving drum, mounting fixtures (9, 9′) intended for coupling with hole openings (3) in the sieving deck and supporting the part that transports ore directed in towards the central axis of the sieving drum. In order to achieve increased flexibility and exchangeability, it comprises first attachment means (10) with which each mounting fixture (9, 9′) is connected in a manner that allows it to be removed with the part (5) that transports ore, and can be adjusted into different angular positions relative to the longitudinal axis of the part (5) that transports ore through rotation around an axis (C) of rotation defined by the first attachment means (10), second attachment means (20) one each of which is supported by a relevant mounting fixture (9, 9′) that can be removed, allowing the mounting fixture to be connected with a hole opening (3) in the sieving deck.
