1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent …

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed ...
The model structure for the one-chamber or multi-chamber cement ball mills have been subject of various researchers. Benzer et al. [21] developed model for open circuit two-chamber cement ball mill. In their structure, the first and second chamber of the ball mill as well as the intermediate diaphragm were all model fitted hence calibrated …
According to statistics released by the Statistical Institute of Mexico (INEGI) in 2019, the annual average production of gray cement was 3.32 million tons, while the previous year it was 3.55, thus registering a decrease of 6.92%. This means that currently the Mexican cement industry is working at 60% of its installed capacity.
