Limestone Production and Its Uses in Saudi Arabia, Limestone is a natural sedimentary rock, abundantly found on the earth’s surface. It is primarily composed of high amounts of calcium carbonate, magnesium carbonate, or dolomite (calcium magnesium carbonate), along with various other minerals.
The production of lime begins with the extraction of limestone from quarries and mines.
What Does the Term “Lime” Mean? The word lime refers to the products obtained through the heating (calcination) of limestone.
Limestone Powder
Limestone powder is one of the most important and widely used natural stone powders across industries worldwide.
It is derived from limestone — a sedimentary rock consisting of calcium carbonate formed over millions of years through the accumulation of seashells and other organic remains.
Zohdy Minerals Egypt supplies high-quality limestone powder for various industries, including construction, agriculture, and chemical manufacturing units.
In this article, we will discuss the uses of limestone powder and its key benefits, Contact us.

The Process of Extracting Limestone Powder in Saudi Arabia
Zohdy Minerals Egypt extracts limestone powder from quarries. The process involves:
- Crushing and grinding limestone rocks until they become fine powder.
- Using advanced heavy machinery operated by skilled professionals to ensure safe and efficient extraction.
- Careful screening of the powder to confirm purity and achieve the required particle size distribution.
Crushing
- Limestone is first fed into a primary crusher to break down large rocks.
- Depending on the required size, it may pass through secondary or tertiary crushers for further reduction.
- Once the desired size is reached, the stones are sorted into various sizes (from several inches to dust-sized particles).
- The processed stones are then washed.
Calcination (Heating)
- Preheating: Limestone is preheated by direct contact with hot exhaust gases from the kiln. It is then transferred by conveyors into lime kilns.
- To achieve calcination, a large amount of heat must be transferred from the fuel to the limestone. This occurs in two stages:
- Calcination: Fuel is burned in hot air coming from the cooling zone. As the limestone moves down the kiln, it converts into quicklime (calcium oxide), releasing carbon dioxide (CO₂).
- Cooling: The quicklime leaving the calcination zone is cooled by contact with cold air.

Types of Kilns
Among the different kiln types, the rotary kiln is the most widely used:
- A slightly inclined horizontal rotating cylinder.
- Limestone is fed from the upper (rear) end, while fuel and combustion air are injected from the lower (front) end.
- As the limestone travels downward, it is gradually heated until it transforms into quicklime.
- The quicklime is discharged into a cooler, where the outgoing air is used to preheat the combustion air.
The quicklime produced can either be sold directly or further processed into hydrated lime.
Production of Hydrated (Slaked) Lime
- Quicklime is crushed.
- A controlled amount of water (around 1% of raw material weight) is added.
- The final product is classified and checked to ensure it meets customer specifications before delivery.
