Types Of Cement Kiln

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.

The cement kiln

However, new cement kilns are of the dry process type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.

What is a Cement Kiln? (with pictures)

Portland cement is probably the most famous form of hydraulic cement, although a number of other types of cement can be made in a cement kiln. Many people are familiar with cement in the form of concrete, a material made by mixing an aggregate such as crushed rock with cement to form a very durable, strong mixture.

Cement Types

In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.

Types of Kilns | HowStuffWorks

The three most common types of kilns are electric, gas and wood. Electric kilns are probably the most common type of kiln used in ceramics. Theyre comparatively inexpensive, and small ones can plug directly into a 120-Volt wall socket, making them accessible to small pottery operations.
