What’s the Principle of Selection Rotary Kiln Refractory Lining?

Refractory material is an important material to ensure the normal operation of cement rotary kiln. Its performance, design level and masonry process will affect its service life, kiln operation rate and clinker quality. Many factors, such as the stress experienced by the refractory material during the operation of the cement kiln system, will affect the refractory used in rotary kiln. Generally, the design of rotary kiln refractory lining in the rotary kiln firing system needs to be selected according to certain principles according to the variety and performance of the cement kiln refractory materials.

A castable refractory lining configuration with a working layer, insulating layer, and a ceramic fiber backing.

A typical refractory brick lining configuration with a working layer and an insulating layer.

The selection principles of Rotary Kiln Refractory Lining are as follows:

① Choose refractory materials according to the production method and kiln type.

② Use refractory materials according to the specifications of the kiln.

③ Select refractory materials according to the nature of the raw materials and fuels used.

④ Choose refractory materials according to the heat load in the kiln.

⑤ Select refractory materials according to the stress distribution and thermal distribution in the kiln.

Cement rotary kiln is the most advanced rotary kiln on the market. After years of technical innovation and practical application, the selection of refractory used in rotary kilns has also accumulated rich experience. More refractory products for the rotary kiln refractory lining, such as spinel refractory, dolomite refractory.
