In the field of ceramic tile manufacturing, uniaxial pressing has traditionally been used for powder compaction. However, in the last 20 years, alternative methods have emerged for shaping large-sized plates. During uniaxial pressing, the granulated powder is placed in a metal mold and compacted through the application of uniaxial force using hydraulic presses. This process has been extensively studied and optimized over the past 50 years, offering great control over the density and uniformity of the final product. On the other hand, alternative methods for shaping large plates include techniques developed about 20 years ago to manufacture porcelain stoneware plates up to 2000mm wide and over 3000mm long. These techniques are less common and less studied than semi-dry uniaxial pressing but allow the production of larger products that can later be cut into smaller pieces. The main objective of this research project is to deepen the understanding of the physical mechanisms underlying the compaction process of large ceramic plates. It seeks to understand how the technologies used for large plates allow transforming a bed of granulated powder into a compact solid with a porous microstructure suitable for further processing and obtaining a ceramic product with the required physicochemical properties. Additionally, this study aims to develop simulation models capable of reproducing the behavior of the powder in large plate compaction equipment.
