Dec 20, 2019· The cylinder of the rotary kiln's main structure is the kiln shell, rim, and thrust roller. Shell is the main part of the rotary kiln. It is a steel plate with a 40mm thickness, which is near the rim. Because of the high load-bearing, the thickness near here is much thicker. There is a layer of 200mm refractory bricks on the inside of the kiln.
