The kiln head and kiln tail sealing device adopt advanced technology to ensure the reliability of sealing. Compared with the same type of equipment, cement rotary kiln has low heat consumption and less energy loss, which can reduce investment costs. The cement rotary kiln is often used in the new dry process cement production line.
The makeup of a kiln. During the operation of the rotary kiln, flames can reach temperatures as high as 1900°C (3452°F) in order to heat raw materials to roughly 1500°C (2732°F). As a result, these materials become partially molten and undergo a series of physical and chemical reactions to become the primary constituent of cement.
The vertical shaft kiln is the earliest invented cement kiln and was widely used in cement plants around the world before the rotary kiln appears. In the 20th century, the vertical kiln in most developed countries is gradually replaced by a type of more advanced and environment-friendly cement kiln, the rotary kiln.
