Introduction of rotary kiln structure

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.
