Cement Kilns: Planetary Coolers
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 involved perforating the …

Cement Clinker Quality Control - AGICO Cement Plant
In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.
