Cement Manufacturing Process The cement manufacturing process typically involves quarrying, drying grinding, kiln burning cooling, finish grinding, and packaging. Each of these process steps are described in the following sections.
2 The production of cement is an energyintensive process. Typically, energy consumption accounts for 2040% of production costs. In 2008, the cement industry spent about billion to purchase energy; around billion of this was for electricity and billion for fuels.
The Operating Principal. Pulverization takes place in the central chamber of the MicronMaster® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved.
