The authors propose a new method of predictive replacements of belt sections in a con-veyor belt loop with their refurbishment based on their condition recognized by specially designeddiagnostic devices: DiagBelt and BeltSonic. Selection of the moment for belt replacement is madeon the basis of forecasted state of its wear, when steel cable failure density exceeds the selectedthreshold or the percentage of belt covers abrasion exceeds the permissible level. The use of doublebelt refurbishment extends the total belt operation time, but without diagnostics, the reconditioningsuccess rate is relatively low. Visual inspection allows only an uncertain assessment of cable condition.New devices give precise assessment of their condition and allow the selection of a non-linear rate ofbelt condition based on consecutive scans. The assessed condition of the cables is the key factor insuccessful belt refurbishment and obtained cost savings. Additionally, diagnostics can help extendbelt life. Identified failures can be repaired in order to prevent accelerated belt degradation. The useof diagnostics in the current replacement strategy significantly improves the economic efficiency ofbelt reconditioning. The reuse of the belt core ensures efficient use of resources and reduces the levelof waste, which fits into the circular economy.
