Production Process — Tiles & Bricks Europe

Drying and firing are the most energy-intensive steps of the production process and the industry has made major investments to reduce energy consumption and CO2 emissions. The key improvements are linked to the development of better designed driers and kilns, the recovery of excess heat from kilns, the use of high-speed burners and the automated control of drying and firing regimes.

 · The SiO 2 content was also analyzed to compare with the raw materials. The degree of amorphization calculated from X-ray diffraction (XRD) data of silica increased with grinding time. The band intensities of Si O Al and Al OH were decreased by the grinding process, which was beneficial to the subsequent leaching.
