Rotary kilnrefractory is one of the most costly components of the system, so frequent replacement is typically not cost effective. Refractory protects thekiln shellfrom the high temperatures passing through the unit. When refractory is allowed to fail, thekiln shellcan become damaged, even requiring total replacement in extreme cases.

Everything depends on design. Generallykilnsdiameter vary from 3 to 6m, and length from 40 to 200m. From maintenance point of view very important parameter isshellthickness: 20mm – smallshellthickness; 40mm – standardshellthickness. There is also some useful parameter ofrotary kilndesign – thickness / diameter ratio.
Rotary Kiln Vibration Large,slow moving equipmentsuch asrotary kilnswill have a low natural frequency of vibration which in some cases could coincide with a kiln speed. Were this to occur, there would be a pronounced vibration of the kiln on the supporting rollers, and knocking and pounding in the main gear and the gear reducer.
Jun 26, 2018· Roller adjustment-and-skew 1. Skew, more than any other mechanical adjustment, is the least understood, the most misused, and is often the most troublesome mechanical issue with akiln. DEFINITION: Skew is the position of the roller axis with respect to turning axis of theshell.
At 400°C, theshellloses 50% of its tensile strength and, over that temperature,shell distortionis permanent. This local distortion may reshape theshellor crack it which effects the load distribution and energy consumption. Thetyresand rollers wear over time, depending on their contact form. Even thepieritself slowly degrades.
