Lime kilns (i.e., active lime kilns) are used for roasting active lime and lightly calcined dolomite used in steel plants and iron and alloy plants. The most commonly used portland cement clinker in the cement industry has the main chemical components of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide, and the main mineral components of tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. The Portland cement clinker is ground together with a proper amount of gypsum to obtain the Portland cement.

In the process of calcining cement, due to the material limitation of cement, in the practical operation process, the following problems exist:

(1) when the traditional cement is calcined in the rotary kiln, due to the limitation of cement materials, in the process of calcining the cement, clinker of the cement is easy to adhere to the inner wall of the rotary kiln, so that part of the clinker of the cement remains on the inner wall of the rotary kiln, and the working efficiency of cement calcination in the rotary kiln is influenced.
