The invention relates to a concrete block producing device (1) and to a method for producing colored concrete blocks using a concrete block producing device which comprises a block molding machine (2) having a block mold that can be supplied with fresh concrete from a concrete hopper (3, 4). Said concrete hopper (3, 4) can be supplied with portions of at least two differently colored fresh concretes in a controlled manner by a dosing device, said dosing device comprising at least two dosing chambers (11, 12) and a transport device for transporting the differently colored fresh concrete portions to the concrete hopper (4). The transport device comprises at least one positioning unit for guiding the colored fresh concrete from the dosing chambers (11, 12) to the concrete hopper, said positioning unit being designed to supply defined positions (31, 32, 33) in the concrete hopper (3, 4) with differently colored fresh concrete portions. |
