SCENARIO FOR THE SECTOR
The industrial production process of ceramic tiles

We can identify two different types of industrial production processes for ceramic tiles:

SINGLE-FIRED: the raw material is produced with a wet process and subsequently spray-dried. There is only one cooking phase, following drying and glazing.

DOUBLE-FIRED: the process, in this case, is dry. There are two firing phases: In the first, the sintering of the support takes place. In the second, the firing of the glaze.

Production cycle of ceramic tiles

The problem he submitted to us concerns the design of a system for the internal washing of the glazing machine, for the “waterfall” application of glazes on the tiles.

THE PROBLEM

The customer who contacted us is a manufacturer of machines and systems for the ceramic industry.
The problem he submitted to us concerns the design of a system for the internal washing of the glazing machine, for the “waterfall” application of glazes on the tiles.
The machine consists of a minimum of 3 to 5 modules: an input module, from one to three glazing modules, and an output module.

The central modules for glazing are equipped with lances for glazing the tiles. An electronic management system synchronizes the movement of the spray lances with the crossing motion of the pieces to be glazed, avoiding overlapping the different passages.

The customer’s request was to design an automatic system for the internal cleaning of the glazing machine. It is essential to promptly remove the glaze from the machine to compromise the quality of the subsequent glazing cycle.
The priority areas to wash are the bottom of the tank, sides, belts, and the nozzles of the lances that spray the enamel.

SOLUTION

The technical office of PNR Italia has developed a modular and effective system for the internal cleaning of the enameling machine.
The solution, which uses only water without detergents, involves the installation of 4 manifolds for each central module, 2 on each side, at the top and bottom.
Each manifold is equipped with J flat jet nozzles. Depending on the position of the pipe, the number and positioning of the nozzles may vary.
