Energy costs play a major role in the cement production process. As much as 60% of total cost is allocated to energy and 18% to the consumption of electrical energy. Historically, energy cost ...
PLC helps in making the automation more flexible. SCADA systems became popular to arise the efficient monitoring and control of distributed remote equipment. Cement plants are one of the largest consumers of energy. Their electrical energy costs account for about 15 20 percent of the total production cost.
The case study plant has a full cement process line from mining to cement finish grinding. It has a production capacity of 1700 tons of clinker and 4000 tons of cement. The clinker produced is not sufficient to make all the required cement and therefore the plant import some clinker to meet the deficit.
Empirical study of a type of cement plant. The LN cement plant, located in the southwest of Shandong Province, was considered as a case study for the mass flow and balance analysis. This cement plant operates on a dry process line with a fivestage suspension preheater and an inline precalciner. The kiln is 4 m in diameter and 60 m in length.
