Raw material preparation
Cement manufacturing begins with the extraction and preparation of the raw material – a process section covering all activities from the quarrying of limestone to the feeding of raw meal into the preheater.

The aim of an optimum raw material preparation process is to provide the subsequent burning process with a raw meal whose quality and homogeneity assures the economical production of high-quality cements.

This depends on precise knowledge of the materials used (raw materials and fuels) and on careful selection of a suitable production process, including the crushing, blending, storage, homogenisation, grinding and analysis systems.
