Our OK Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK Mill is the natural choice for grinding blended cements with one or more wet components.

Cement Extraction and processing | Britannica

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.
