What is a cement kiln?
Cement is a very important building material. It is the most widely used man-made product in the world. Cement is simply a mixture of limestone, clay and sand that has been heated to over 2,000 degrees Fahrenheit in a kiln. The “clinker” (a hard mass of ash and clays) that results from this process is cooled and ground into an incredibly fine powder, which can then be used as an ingredient in mortar, stucco and concrete.
It takes a lot of energy to make cement (approximately 400 MJ/tonne), which has led to more sustainable ways of producing it. One way to do this is by using a cement kiln (or lime kiln), which takes advantage of the heat already generated by burning fossil fuels in order to produce cement clinker with less effort than traditional methods require.
Why do we need cement kilns?
A cement kiln is the device that heats limestone and shale to 2,700 degrees Fahrenheit and transforms them into the most important material in modern construction. Without cement, the buildings that define our cities would not be possible. Every house, office building, parking garage, apartment complex, hospital and school was made possible by a kiln-cooked mixture of limestone and shale.
Have you ever watched a construction crew pour a basement floor? As they lay down layer after layer of concrete reinforcement mesh, or rebar as it’s often called, you may have wondered: how did mankind create this strong substance? And who first thought to combine rocks with water to make something more useful than either ingredient? How are these materials heated to such high temperatures without blowing up? And who designed the kilns that make all this possible?
Concrete is the most frequently used construction material in buildings today.
Over the past century, concrete has become the most commonly used construction material in our world.
Concrete is used when building bridges and roads, in hospitals and schools, in offices and homes. Concrete is an extremely durable material that will last hundreds of years with very little maintenance.
Besides being low cost and durable, one of the most important advantages of concrete is its strength and safety features — making it the best choice for structures built to withstand extreme weather conditions or other destructive forces.
Concrete is especially useful in areas where traditional building materials are unsuitable.
Concrete is especially useful in areas where traditional building materials are unsuitable. For instance, concrete is ideal for use in regions that have a high seismic activity, because it can bend without breaking. In addition, concrete is a good choice for construction in areas with high water tables or high salinity levels. Concrete’s versatility also allows it to be used for projects that require resistance to extreme temperature changes and wind loads. Finally, concrete is an excellent material to use in humid climates where thermal conductivity is a concern.
Cement itself is a chemical, but it can be produced more efficiently with a cement kiln.
In the manufacturing process, “raw mix” is blended together with limestone and other minerals to produce cement. However, this raw mix cannot be used immediately because it must be heated in a kiln. The heating process—or sintering—is the very high heat (around 2,700F) that turns the raw material into clinker.
At some point during this complex process, you might ask yourself:
“What is a cement kiln?”
Let’s take a step back and answer that question in more detail.
A cement kiln is a heated building that uses compressed air to produce heated molten material called clinker from raw materials, primarily limestone and shale.
A cement kiln is a heated building that uses compressed air to produce heated molten material called clinker from raw materials, primarily limestone and shale.
The resulting clinker is cooled and ground into a fine powder with a small amount of gypsum. This product, known as Portland cement, is used in mortar and concrete for everything from sidewalks to skyscrapers.

Cementing technologies such as this have been known for centuries and were used in antiquity to produce white lime for stucco painting, mortar for the construction of buildings and concrete blocks for fortifications.
