Sampling from cement kilns or preheater outlets

3 Sampling from cement kilns or preheater outlets 

Several investigators have examined samples from rotary kilns during normal operation. In one such study, Weber (W13) obtained samples, and 

Wolter (W14) determined the phase compositions of kiln inlet meals from about 20 plants using cyclone preheaters, usually with precalciners. XRD showed that the decomposition products of the clay minerals were especially reactive, though some reaction of quartz also occurred. Phases detected, and some notable absences, were as follows
