Changes of damage to the belt core that are not controlled during the exploitation can lead to dangerous accumulation of the defects (strains) in the cross cross-section. It can lead to serious weakness and even rupture of the belt. Early detection of the mic rodamage of the covers and evaluation of the increase speed of the damage allows the user to plan maintenance more precisely. Furthermore, it allows more effective cost management when conveyor belt maintenance is scheduled. In this paper, geometric data o f ...

Research concerning magnetic diagnostics of the conveyor belt with steel cords was focused on its sections. In this paper authors are focusing on the extraction of the diagnostic parameters for the technical evaluation of the condition of the splice in belt conveyor. Data used for the analysis were acquired from the belt core testing using HRDS system. Parameters that are used in this paper take into account and can define its condition in the specific locations. Parameters were analysed and research shown influen...

In Polish mines several belt replacement strategies are applied. They have been discussed in the context of strategies for machinery maintenance. The common practice is to base belt replacement on its condition established through visual inspections. Two main policies have been recognized: replacements in order to prevent costly downtimes of conveyor systems (in underground mines) and replacements in order to assure profitable refurbishment of worn out belts (in surface lignite mines). In order to choose the most ...

Conveyor belt loop operates in a system comprising a series of belt segments and the splices between them. Splices are the weakest parts of a loop. Depending on the splicing technology, the spliceпїЅs strength, durability and reliability may vary significantly. Vulcanized splices offer the highest strength and durability. In the case of steel cord belts, such splices are practically the only technology available. In the case of textile belts, adhesive and mechanical splices may also be used. Although mechanical sp...
