Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand clay fulfill the need of silicon, iron and aluminum.

The suspension preheater (SP) configuration of cement plants in Indonesia varies depending on the plant manufacturers. According to the classification proposed by FL [22], the dry process preheater and calciner configurations of cement plants are divided into several types such as conventional preheater (CSP), inline calciner (ILC), inline calciner using excess air (ILCE), separated ...

Abstract. An improved differential evolutionary cement mill operation index decision algorithm based on constraint control and selection strategy is proposed to address the problem that the operation index is usually decided by manual experience in the cement mill operation process, which causes unqualified cement specific surface area and excessive cement mill power consumption.
