A method for producing engineered stone slabs includes depositing a plurality of fragments of composite material into a pile on a surface, which is supported by a supporting structure, and depositing colorant in a predefined region onto at least part of side walls of at least some of the plurality of fragments of the composite material. The method then includes using a press roller to press, flatten and stretch the plurality of fragments of the composite material into a slab, after depositing the colorant.

A method for producing engineered stone slabs including steps of depositing a composite material onto a supporting structure; disrupting the composite material using a plurality of stirring devices attached to a shifting structure; depositing colorant in a predefined region in the composite material using a spray device to form a colored disrupted composite material; and using a first device to press, flatten and stretch the composite material into a slab after disrupting and depositing colorant. The step of disrupting may occur before, after, or during the step of depositing colorant. The step of disrupting the composite material or the step of depositing colorant may include causing the shifting structure to move along a width of the supporting structure. Prior to depositing the composite material onto the supporting structure, and after compressing the composite material, the composite material may be fragmented into a plurality of fragments of composite material.

A method for producing engineered stone slabs includes depositing fragments onto a surface and using a height limiting device to disrupt the fragments so a height of the fragments at the highest point from the supporting structure is substantially the same height as the height limiting device from the supporting structure. The method then includes using a digital printing device, in a first digital printing step, to print an image onto at least part of a top and side walls of at least some of the fragments, and then depositing additional composite material onto at least some of the fragments. The method further includes using a digital printing device, in an additional digital printing step, to print an image onto at least part of the additional damp composite material, and then using a press roller to press, flatten and stretch the fragments into a slab.

A plant for manufacturing ceramic articles comprising two feeding devices, each of which is configured to contain a powder material of a respective type and feed this powder material to a conveyor assembly. The plant further comprises an operating device, which is configured to allow the powder material to exit selectively from zones of the feeding devices arranged in succession crosswise to the movement direction, moving vertically and independently from one another a plurality of transfer moving parts, each provided with a transit channel through which the powder material moves to reach the conveyor assembly.

A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.
