A cement mill is used to make clinkers, which are key in many types of concrete. The chief constituent of Portland cement is a sintering product of limestone and aluminosilicate known as clinker. This hard, pebble like material is the ingredient in cement which causes it to "cure" and harden to form the mortar or concrete used so extensively in construction.
