Introduction of rotary kiln structure

Kiln Cylinder. It is the main body of the rotary kiln. The thickness of the kiln shell steel plate is about 40mm. Near the tire ring, because the bearing capacity is relatively large, the kiln shell steel plate here is thicker. The interior of the kiln shell is covered with a layer of refractory bricks of about 200 mm.

Rotary Cooler for Small Cement Plants | Rotary Drum

The cold air generated by the cooling fan moves from the lower end of the cylinder to the upper end. When it meets with the convective material, thermal energy is transferred from materials to airflow. Bearing the heat of materials, the cooling air is discharged from the upper exhaust outlet and recycled back to the rotary kiln as secondary air.

Cement Kilns: Design features of rotary kilns

The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscoe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 …
