Abstract
Cement production involves the processing of raw materials that contain SiO2, Al2O3, Fe2O3, CaO, MgO, LOI (loss of ignition) SO3, K2O, Na2O, TiO2, P2O5 and Cl, etc. to produce the synthetic mineral mixture called “clinker”. Bench-face chemistry, a critical element, plays a significant role in the subsequent blending of raw material with other additives to meet the blending requirements and this element requires study of several different quarry plans in order to select the one requiring the fewest purchased additives. This paper presents a cement quarry production sequencing algorithm, which is used to generate multi-period quarry plans, satisfying geometric (slope) and production capacity constrains. The benefits of this methodology are demonstrated on a case study.
