This study examines the feasibility of manufacturing glazed porcelain tiles with a more environmentally friendly
manufacturing process, by reducing water and thermal energy consumption. The process studied in this paper is dry milling
in a pendulum mill, with subsequent granulation (in order to obtain a press powder with similar flowability to that of spraydried
powders).
The different morphology of the new granulate with respect to the standard spray-dried granulate modifies the microstructure
of the green compacts and thus, their behaviour and fired tile properties. In order to obtain porcelain tiles with the required
properties (water absorption, mechanical strength,…) changes have been made in the raw materials mixture and in the
processing variables.
Finally, porcelain tiles measuring 50x50 cm have been manufactured at industrial scale with the new granulate using a
conventional firing cycle, obtaining quality levels identical to those provided by the spray-dried granulate. These results
open the possibility of preparing porcelain tile body compositions through a manufacturing process alternative to the
standard one, more environmentally friendly and with lower costs [-]
