analytical and numerical stress analysis of the rotary kiln ring

Original scientific paper. This paper presents an analysis of the stress distribution on the outer surface of the riding ring of rotary cement kiln during working cycle using both the theory and finite element simulation. In the theoretical analysis, the total stress is obtained as a combination of bending, thermal and contact.

Kiln Shell Laser - Industrial Kiln & Dryer Group

11 December 2014. User Manual: Kiln Shell Laser. 1. INTRODUCTION: The Kiln Shell Laser is a measurement tool, which measures the deformations in rotary kilns or dryers or other slow rotating cylinder during operation. The tool can be used to measure just one cross section, a specific area containing a few cross.

Nov 16, 2017 . Primary Stress and Secondary Stress. The pressure vessel codes define two important 'classes' of stress. A primary stress is related to mechanical loading directly and satisfies force and moment equilibrium. Primary stress that exceeds the yield stress by some margin will result in failure. By contrast.
