Cement Kilns Design Features Of Rotary Kilns
The most recent precalciner kilns, because most of the processing is done in the preheater, can have very low length/diameter ratios (14) and this reintroduces the possibility of mechanically simplified twotyre kilns. Splined tyres are combined with selfaligning roller assemblies and throughtheroller drives (see below), allowing the system to continue to function even if the kiln is bent.
