Abstract (en)
A method for forming tiles or tile accessories of extruded porcelainized ceramic stone, comprises the operation of preparing at least two pastes, typologically defined as porcelainized ceramic stone, having different colours; feeding said at least two pastes directly into the chamber of a screw extruder (6); subjecting the mass advancing within the extruder (6), downstream of the screw (7) and upstream of the die (13), to the action of at least one flow deviator means (9, 10, 11, 12); separating portions corresponding to tiles or tile accessories such as steps or skirting; subjecting the tiles or tile accessories obtained in this manner to a drying cycle; subjecting the dried tiles or tile accessories to a firing cycle.
