Limestone quarry production planning for consistent supply
A long term production planning of limestone quarry is presented to supply consistent quantity and quality of limestone to a cement plant. A case study from Indian cement industry is presented where the cement plant has a captive limestone quarry. The objectives of this study are: (a) to investigate how long the limestone quarry can alone supply the desire quality and quantity materials to the

Cement Plant
The Ramla cement plant (see Fig. 1 for an aerial photo of the plant) has been in operation for 46 years. The original process at the Ramla cement plant to produce cement from limestone, which is the base material of cement, was a so-called wet line process. The original wet line had a capacity of 1,800 TPD (Tons Per Day).

How Is Cement Produced in Cement Plants | Cement Making
Cement plants are usually built near the quarry of limestone so the quarried limestone can be transported to the cement plant directly by belt conveyor or other conveying systems. If the distance between the quarry and the cement plant is too long to use conveyors, the limestones will have to be transported by trucks, which means higher transportation fees and inconvenience.

How Cement Is Made
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
