“…The finite element software ANSYS was engaged to analyse the structure stress and the thermal stress distribution in the cylinder. The analysis results are helpful in the design and optimization of the rotary kiln cylinder [3][4][5]. The predicted results of outer kiln wall temperature agree well with measurements [6].…”

The rotary cement kiln forms a major part of any cement works. The kiln is a large cylindrical structure where the raw materials are brought together and heated to form clinker, the base material of cement. To ensure production plant reliability and product quality an understanding and evaluation of the kiln design parameters is of paramount importance. This paper presents a solution for evaluating the mechanical strength of the shims, vital components in the drive system. These parts transmit the rotational drive to the kiln drum, and are subject to large mechanical and thermal stresses. The results of this study enable a reliable plan for preventive maintenance of the kiln furnaces to be developed. The methodology employed detects the mechanical and thermal stresses distributed on the surface of the shim while the working cycle are active, and uses both mechanical theory and numerical simulation by the Finite Elements Method (FEM) under the ANSYS software. The numerical results provide an authoritative guide to the accurate prediction of the optimal preventative maintenance interval for the rotary cement kilns drive element.

This paper focuses on the dynamic response of three asymmetric and nonlinear packaging systems (ANPSs) of practical transport package under random excitation. Next to presenting the displacement probability density functions (PDFs) of ANPSs derived through FPK equations, the influences of the excitation grades and the characteristic parameters (such as the damping, the nonlinear stiffness, and the strain) of packaging cushion materials on the response are discussed in detail. Then, the generalized PDFs of the response peaks are defined and examined by three common distributions. The investigation shows that “inverse excitation cushion factors” (IECFs) have a significance on effecting the displacement PDFs approaching different distributions. Most PDFs of the unilateral response peaks approach Rayleigh distributions and present non-Gaussian characters. The present methods are verified through the validation numerical solutions. Furthermore, the application of the scheme for fatigue damage evaluation of the transport package is carried out.

“…The analysis of the displacement sensor signal is based on the steady periodic signal, which is difficult to adapt to the needs of actual complex working conditions. The Danish company FLSmidth proposed using an inclination sensor to monitor the axial force of the rotary kiln supporting wheel [3][4], while, this method is only limited to axial force monitoring and does not consider radial forces. This article proposes a method for force monitoring of the rotary kiln and designs an online monitoring system to monitor the axial force and radial force of the rotary kiln supporting wheel in real time.…”

Failure of the supporting wheel of the rotary kiln may directly lead to abnormal operating conditions of the kiln. Monitoring the operating status of supporting wheels and providing early warning can greatly reduce the occurrence of rotary kiln failures. This article proposes an online monitoring system for the force on the supporting rollers of a rotary kiln based on the VMD algorithm, which monitors the axial and radial forces on the supporting rollers. This system consists of a laser displacement sensor, ZigBee communication technology and VMD signal processing method to monitor changes in the axial displacement and radial eccentricity of the supporting wheel. This system has been proven effective after actual deployment in a cemeWnt plant in Sichuan. It can prevent and reduce possible failures of supporting wheels, extend the operating life of the rotary kiln, and increase economic benefits.
