Cement Production: How Cement Is Manufactured CEMEX UK

View the interactive animation of the cement production process to learn how cement is made by CEMEX. 1. Mining the raw material. Limestone and clay are blasted from rock quarries by boring the rock and setting off explosives with a negligible impact of the environment, due to the modern technology employed. 2. Transporting the raw material.

Modeling and Optimization of Cement Raw Materials

This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear timevarying GNLTV model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints. Different objective functions are presented to acquire
