Operation-oriented method for testing the abrasive wear of mining chain wheels in the conditions of the combined action of destructive factors
DOI 10.12914/MSPE-12-03-2015
Abstract: This paper presents a general characteristic of a rig for chain wheel testing in the conditions reproducing the actual op-erating conditions of conveyor elements in the rolling and sliding motion. This test rig allows performing wear tests in the presence of an abrasive material, corrosive factors and additional dynamic excitations in the form of steel beaters. The paper also describes a methodology of abrasive wear tests of chain wheels that allows determining the value of the linear wear of chain wheels and presents the test results for the materials typical of armoured face conveyors.
Key words: wear, chain wheels, maintenance
