Abstract: The invention relates to a mobile apparatus and a method for concrete production, comprising a cooling apparatus for cooling bulk material, in particular aggregates for concrete production. The cooling apparatus (100) comprises a bulk material hopper (110), a wetting apparatus (120) and an air supply apparatus (130). The cooling apparatus has a bulk material feeder (140) for feeding bulk material into the bulk material hopper via a bulk material feeder path (141), the bulk material feeder and the wetting apparatus being adapted and disposed in such a way that bulk material to be fed comes into contact on at least one part of the bulk material feeder path with water that is being discharged from the wetting apparatus.
Abstract: The invention relates to a compact leftover concrete recycling device for mobile use on a concrete transportation vehicle and/or concrete delivery vehicle, comprising a recycling chamber with a baffle plate, an inlet opening for leftover concrete and an outlet opening for recycled leftover concrete as well as two, three or more high-pressure nozzles, wherein the baffle plate, the inlet opening and the outlet opening are designed and arranged such that leftover concrete filled into the recycling chamber through the inlet opening impacts a reception section of the baffle plate, passes a recycling section of the baffle plate and then leaves the recycling chamber through the outlet opening, and wherein the high-pressure nozzles are arranged and designed such that water jets delivered from the high-pressure nozzles impact the recycling section of the baffle plate.
