Research about influence of the tension forces, asymmetrical tensioning and filling rate of pipe conveyor belt filled with the material on the contact forces of idler rolls in hexagonal idler housing

Abstract

Reliable operation of the pipe conveyors requires continuous monitoring and evaluation of their selected indicators. Asymmetrical tensioning of the conveyor belt is the serious negative and undesirable operational situations. There is still remaining without answer one important question, namely it is the question whether such improper kind of the tensioning is able to cause changes of the contact forces and in such a way also to influence negatively the processes of conveyor belt wearing or if the asymmetrical tensioning has a relevant impact on the contact force values. The main task of this article is to analyse relations among the tension force values, asymmetrical tensioning and filling rate in the cross-sectional area of the piped belt, which is filled with the material, with regard to the values of the contact forces that are acting on the individual idler rolls arranged in the hexagonal idler housing of the pipe conveyor.
