摘要
The process for the manufacture of slabs of ceramic and/or stone material, comprising the phases of: - supplying of at least one basic material (B) of the ceramic and/or stone type in the form of powder and/or granules and/or flakes; - supplying of at least one additional material (A) other than the basic material (B); - dispensing of the basic material (B) on a supporting surface (3) to obtain a slab to be compacted (5); - pressing of the slab to be compacted (5) to obtain a compacted slab (12); where the additional material (A) is of the electrically conductive type and where it comprises, after the dispensing and before the pressing, the following phases: - definition of at least one groove (14) on the slab to be compacted (5), the groove (14) passing through at least one portion of the thickness of the slab to be compacted (5) and extending along a given path (15); - application of the additional material (A) inside the groove (14) to define at least one vein (19) of a color and/or type other than the basic material (B), the application comprising at least the sub-phases of: - electrostatic charging of the additional material (A); - spraying of the electro-statically charged additional material (A); - distribution of the additional material (A) sprayed inside the groove (14); the pressing involving both the basic material (B) and the additional material (A) so applied.
