The coolers in practice were almost useless. Masons, using them up to the 1960s, recorded clinker outlet temperature around 1000°C, and the "quenching" of the clinker, necessary for good quality, was delayed until it fell out onto the conveyor.. A modest improvement in performance could be obtained by fitting a "van der Werp" cooler. This …
