Limestone quarry, quarrying, cement raw materials

Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing.

Cement Manufacturing Process – NPC

Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.

Quarrying Basics - ccaa.au

Quarrying is quite simply the extraction of natural resources from the earth, usually from some form of surface working or quarry site. Quarries produce a range of useful materials, including limestone, dimension stone and rock. In Australia, the most common materials extracted are construction aggregates such as crushed rock, sand or gravel.
