<p>The invention relates to a method for reprocessing unset concrete rests and concrete residues obtained when cleaning devices used for concrete production and transport and concrete reprocessing facilities, which rests and residues are produced when they are recovered in concrete plants and when cleaning mixers, truck mixers and concrete pumps. According to said method, the process stages - adding rinsing water to the residual concrete, diluting said residual concrete, washing sand and/or gravel components out of the residual concrete, classifying and reprocessing said components into coarse and fine-grained constituents using classification, mixing and conveyor devices, obtaining a homogeneous suspension containing concrete, if necessary separately returning all residual concrete components into the concrete production process, and cleaning the machine and plant parts - are carried out automatically in a non-separate manner in an integrated recycling system which is electronically controlled and monitored.</p> |
