<p>1. Process for reusing the moulding material of ceramic reject mouldings, in particular reject bricks, coming out of the press, characterised by the following process steps which take place immediately after the pressing or at the same time as the pressing : a) in response to a reject message, the reject mouldings are conveyed by a transmission gripper of a moulding-positioning device (9) which is arranged downstream of the press (8), into a granulator (1), b) in the granulator (1) the mouldings are comminuted in two stages, first of all to, for example, 50-60 mm in diameter and then to sinter grain size of, for example, 8-16 mm in diameter where the ceramic binder is preserved as a sheath surrounding the granules, c) the granulate coming out of the granulator (1) is fed to a prebunker (2) upstream of the charge bunker (5) of the press (8), d) the granulate is added out of the prebunker (2) in a metered, adjustable amount to the moulding material coming ut of the charge bunker (5) along a conveyor (6), and both are conveyed into a loading slide prebunker (4), e) in the loading slide prebunker (4), moulding material out of the charge bunker (5) is mixed with the granulate out of the prebunker (2), f) the mixture in the loading slide prebunker (4) is passed to the load box of the press (8) and then to the press (8) for pressing.</p> |
