Rotary Kilns are normally gear driven through girth gear mounted over the shell on gear support base, assembled ... Such a ame is projected from a burner-pipe. The fuel for this may be gas, oil or pulverized coal. The fuel could be mixed with air before or in the burner.
1 Suitability of cement kilns for the combustion of secondary fuels. Compared to other high energy-intensive production processes of cement clinker burning process allows a relatively high potential to use secondary fuels [1].This is due to the robustness of the clinker burning process and in its principal layout as a countercurrent process.
On some rotary kilns, the primary air pipe is fixed slightly below the center of the kiln, in an effort to offset the flame buoyancy. Most kilns, however, have facilities for adjusting the position of the primary air pipe and the burners, thus the operator can change flame direction and, to a limited degree, change the shape of the flame.
FL's Uniflow Burner is a rotary kiln burner that offers a versatile processing experience.

Rotary Kilns. Modern rotary kilns can be safely lined with just two types of bricks: 1) high alumina in the calcin-ing and discharge zones, and 2) magnesia-spinel in the lower transition, upper transition, and burning zones. Many new kilns have been successfully commissioned with this simplified lining configuration, with good results.
