Belt training
Published in D.V. Subba Rao, The Belt Conveyor, 2020
Normally, the belt will not wander on a well-engineered, aligned and maintained conveyor structure. But, in reality, belt wanders or runs off-track. This wandering of the belt causes material spillage, component failure and costly damage to the conveyor belt itself. Few of the reasons for wandering or snaking of the belt, to the left or to the right, are indicated in Section 5.2.5.

In this paper, a new design of changeable intelligent logistics system is proposed to deal with this kind of situations. The basic model of a conveyor belt is utilised to keep its original advantages of transporting large quantities of parts, and with enhanced flexibility through modularisation (Huang and Kusiak 1998). The whole system is formed by identical modules with decentralised control. When various manufacturing job tasks are given, the logistics system can be easily manipulated through operations of reassembling these modules due to new job sequence to form novel logistics layouts within factories. In section 2.1, the framework of the proposed logistics system is discussed after further analysis of the problem above, and some preliminaries are introduced. Then, in section 2.2 and 2.3, the implementation of the system will be illustrated, with methods for different stages of the system being discussed separately. Next, simulations are performed in section 3 assessing the overall performances. At last, conclusions will be drawn in section 4 to demonstrate practical applications of the proposed logistics system and further studying directions.
The influence of natural ageing processes on the strength parameters of steel cord conveyor belts

Significant cost of a conveyor belt, which may constitute as much as 50% of the conveyor’s value, necessitates its careful selection. One of the priorities in research on conveyor belts is to determine their life span, i.e. the time span over which they work failure-free and retain their physical and mechanical properties. The span guaranteed by the manufacturers is normally between 3 and 6 years. Extending this span to more than 10 years is possible, on condition that the belts are properly maintained, serviced and inspected, and that the splices have proper tensile strength. Frequent visual inspection of belt condition is impractical, as the length of belt conveyors is increasing while some types of damage are difficult to recognise. In response to user demand, magnetic methods are becoming increasingly popular. These methods allow continuous control and diagnostics of the phenomena which occur in belt core [6–8].
Ultimate pit limit determination for semi mobile in-pit crushing and conveying system: a case study

The use of conveyors as the major haulage method requires the use of one of five possible pit exit strategies. These are discussed in the Mine Planning and Design section of this paper. There are five main types of conveyor belts used in bulk material movement: belt conveyors, pouch conveyors, pipe conveyors, piggy back conveyors and high angle conveyors.
