In this article we will talk about some basic technical concepts about clinkering and thermal zones of the rotary kiln. But what happens inside the cement rotary kiln?
A Rotary kiln is a cylinder which rotates around its cylindrical axis and acts as a device to exchange the heat. The construction, position and alignment of kiln is a essential factor for the smooth operation.
The accurate recognition of the burning state of cement rotary kiln is of great significance to improve the qualified rate of clinker quality, ensure the safe operation of rotary kiln and reduce the production coal consumption of enterprises.
Lining your kiln The following is Höganäs Borgestad's suggestion for lining your kiln, both for standard and alternative fuels. Brick or monolithic? With the exception of the inlet cone and the nose ring, the kiln should always be lined only with brick. Brick heights, which depend on kiln diameter, range from 200 mm and up.
Refractory, or the lining utilized on the interior of rotary kilns, is a critical component in ensuring process efficiency and prolonging the life of a rotary kiln.Here, we'll discuss everything you need to know about refractory, including how it works, the different types, and best practices for preventative care.
Portland cement is produced by one of the most energy-intensive industrial processes. Energy consumption in the manufacture of Portland cement is approximately 110–120 kWh ton−1. The cement rotary kiln is the crucial equipment used for cement production. Approximately 10–15% of the energy consumed in production of the cement …
Cement rotary kilns are commonly referred to as the largest piece of rotating equipment in the world. Ranging in diameter from 10 feet to more than 20 feet, they are often many hundreds of feet long. As the kiln rotates on its rollers, material is transported due to the kiln's low, gradual slope.
Cement rotary kiln is an essential cement equipment in the clinker production. What are advantages of rotary kiln? Rotary kiln manufacturer helps you learn more about cement rotary kiln.

A cement rotary kiln is critical for clinker calcining, and its combustion and heat transfer characteristics can directly affect the production efficiency and quality of cement [5]. In recent years, oxygen-enriched combustion (OEC) in the kiln has been verified as an effective method for saving energy and increasing production.
The advent of the rotary kiln is closely tied to the creation of Portland cement. In 1824, Joseph Aspdin successfully produced an eminently hydraulic lime by cooking at high temperature, in a bottle kiln, a mixture of limestone and clays; he referred to his output as "Portland Cement" [2], [3], [4].
The kiln in cement plant can be divided into cement rotary kiln and vertical shaft kiln. They are both the commonly used cement kiln in the cement production line. AGICO offers quality cement equipment, like cement kiln, cement crusher, etc.
