2 Major Roles of Limestone in Cement Manufacturing

The use of limestone powder to replace part of the cement clinker to produce Portland limestone cement (PLC) has become increasingly popular. Portland limestone cement is popular for three reasons. 1) When burning to form cement clinker, it consumes a lot of energy and releases a lot of carbon dioxide.

Limestone quarry, quarrying, cement raw materials

Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing. Limestone quarries are opencast mines. Often limestone appears as an outcrop right on the surface. At other times it is under an overburden that can vary in depth but is generally less than 3 metres thick.
