limestone quarrying at process cement plant

Stage 1: Quarry Process | Cement Production

Limestone Quarries. Limestone is the chief ingredient in powdered cement. Limestone in most all regions is quarried rock. In brief, Limestone is drilled, blasted and loaded into Haul trucks. From there it travels to a Crushing Unit. Sometimes there is a combination of Primary and Secondary Crushers used to reduce the limestone to a usable size.

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.

Belterra clay could replace limestone in cement production

At least 50-60 per cent of limestone can be replaced by Belterra clay, which provides several advantages when compared with limestone quarrying. The clay has to be removed anyway, so it does not have to be extracted only for cement production. Furthermore, the burning process only requires 1250˚C – 200˚C less than for Portland cement.
