Tight control of every step in production process is of outmost importance for achieving the maximum efficiency and quality of cement From stock pile management production of raw meal preparation of kiln feed and the production of clinker right through to the final mixing of the end product the control is driven by the elemental mineralogical composition and particle size analysisIf the kiln is operating under slightly reducing conditions such as inside the flame plume more volatile and lower melting point sulphur salts will form increasing ring formation The molten salts coat the lime particles and dust forcing it the stick to the kiln wall Dusty kilns will accelerate this mechanism
