Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern pre-calciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln operating campaign

Classification of Brick Kilns Brick kilns first started in pits and walls were added later. A chimney stack was added to improve the air flow or draught of the kiln, and to help burn the fuel more completely. Several variations have been invented over the years with varying degrees of efficiency and cost

This is why firebrick is most commonly used in kilns, furnaces, or other areas that reach extremely high temperatures—both in home and industrial settings. Refractory cement, also known as refractory mortar, is what’s used to secure the bricks together and create the desired structure. It has an improved thermodynamic property in comparison

A kiln should be aligned when it is in operation for four very important reasons: 1. A straight cold kiln has a measurable misalignment at operating temperatures. This is because the shell axis elevation increases by one half of the thermal expansion of the shell diameter. This expansion is the function of the shell temperature and, as such, it
