6 Conventional air circulation systems for roof tiles
Rotary fans or air walls are also employed in roof-tile dryers of conventional design. Unlike air wall dryers for masonry bricks and clinkers, however, air wall dryers for roof tiles have horizontal slit inlets (»23). For the sake of simplicity and easy assembly, round inlets (»24) can also be used.
7 Air circulation systems in rapid dryers for roof tiles
Due to the drawbacks of parallel incidence, as mentioned in item 2.6 (Part 1 in Zi5/2011), other forms of incidence were investigated for roof tiles in various experiments and simulations...
