The present invention relates to a method and system for producing concrete products by casting method by means of casting moulds assembled from corresponding outer and inner moulds, having a program-controlled, automated circulation system having a hardening area 420, a program-controlled, automated manufacturing area 100 and a conveying unit 200. The system also has a manually operable mould assembly unit having mould assembly stations M1 to M4 for manually assisted assembly of a casting mould from corresponding outer and inner moulds, wherein the conveying unit comprises a supply conveying section 222 set up to supply a casting mould assembled in the manually operable mould assembly unit to the automated circulation system under program control.

An apparatus including a first conveyor device including a first conveyor belt; a second conveyor device including a second conveyor belt; a movement device; and a mold device including a mold; wherein the first conveyor device is connected to the second conveyor device so that when the movement device moves the first conveyor device, the second conveyor device also moves with respect to the mold device; wherein the first conveyor belt moves independent of the second conveyor belt; and wherein the first conveyor belt and the second conveyor belt move independent from the movement device. The apparatus may further include a first and second dispensing devices configured to dispense first and second materials, first and second gate devices to control height, and a computer processor to control the various components and the resulting ratio of first material to second material in a processed slab.

Means for dispensing a powdery coloring substance onto the surface of a mix comprising stone, stone-like, glass or ceramic material. The means comprise at least one dispensing device for containing and dispensing a powdery coloring substance and at least one spreading device. The spreading device comprises at least one moving perforated plate which receives a metered amount of said coloring substance from the dispensing device and distributes it over the surface of the mix.
