Optimization of stockpile blending at cement plant in Pakistan

For the expansion of the production Fauji Cement Company built a second kiln line. At this occasion Fauji Cement Company also invested in a SpectraFlow online analyzer and a pre-blending software to optimize its stockpile blending as in the expanded operation both lines are fed with material from the existing stockpile and therefore the turnover at the pile will be significantly higher. This optimization is based on the raw material analysis of the SpectraFlow online analyzer, which is used by the pre-blending software to evaluate the best setpoints of the clay and limestone feeders into the crusher. This paper explains the setup of Fauji Cement’s operation and the results of the stockpile blending optimization with a special focus on the ABB SpectraFlow online analyzer optimization and performance.
