Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 2 O).

Concrete Grinding. Solution Concrete Grinding is a modern technique to eliminate trip and fall hazards. The process uses a Scarifier Concrete Grinder and Dry Surface Grinder to sand down the raised side of two joining sections of concrete. Within a matter of minutes, the raised side can be ground down permanently eliminating the "trip and fall hazard".

Cement Cement Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
