Most linings within the suspension preheater are comprised of two components: a dense working lining and an insulating layer. RCast 3, RCast 3-35, and, QuikLite 3 are commonly selected for the insulating layer. Gunite refractories are commonly used for maintenance in the upper preheater, including RCast 15GM, Progun 26LI and ...

The core of the pyroprocess of each modern cement kiln is the preheater. Most substantial thermo-chemical reactions of the cement process occur in the riser ducts and in the calciner(s) and certainly in the sintering zone of the kiln. Modern suspension preheater kilns usually have 1 or 2, in a few cases also 3 strings with 4 or 5 stages.

The FL In-Line Calciner Preheater System offers a full capacity range for today's plants, up to 14,000 t/d or more. It can be built with single or multiple preheater strings with up to 6 cyclone stages. The ratio of firing in the calciner is 55-65% of total, while achieving a calcination rate at the kiln inlet of 92-95%.
