Abstract
The study presents the results of a study of belt conveyors working in the mining industry and the new design of support rollers is proposed.
Highlights
Belt conveyors are the most common type of continuous machines in industries
In addition to belt conveyors, rollers are used in other Machines with Continuous Transport (MCT), for instance, for transportation and packages of piece goods in rolling conveyors and various kinds of storage silos, where the cost of the rollers amounts 50-80% of the cost of continuous machines
Justification of the research direction: At present the lifetime of rolling supports working in hard conditions with a dusty environment and large-sized goods, which is typical for the mining industry averages on linear sections 12000-15000 and 5000 h on loading sites
Summary
Belt conveyors are the most common type of continuous machines in industries. The cost of rollers amounts 25-30% of the total installation cost. 40% of the total cost of upkeep is the share of rollers that determines efficiency, energy intensity of the belt conveyor and influences on the belt durability. In addition to belt conveyors, rollers are used in other Machines with Continuous Transport (MCT), for instance, for transportation and packages of piece goods in rolling conveyors and various kinds of storage silos, where the cost of the rollers amounts 50-80% of the cost of continuous machines. Reliability enhancement and durability of rolling supports of conveyor systems is an urgent task
