“…The investigations include the in uence of the energy and shape of material lumps on the type of damage to the belt and its core [1]. These are also classi ed [2,33,38] with the purpose to increase belt puncture resistance by modifying the belt support [21,26], the belt design [4,19,39], the composition of the rubber mixture [1] or the introduction of breakers [ ]. The magnetic system [3] or other tools for evaluating the effects of punctures [17] allowed a non-invasive inspection of cores and belts subjected to punctures.…”

Belt conveyors are used for transporting bulk materials over distances. The core of the belt, by transferring the longitudinal stresses and ensuring proper frictional coupling of the belt, enables belt movement and transportation of materials on its surface. As the belt cover and edges are used, the belt becomes abraded, and the core is subject to fatigue. The result is the development of cracks in rubber covers across the belt, which leads to the development of damage not only along the cables (the natural direction of water migration and corrosion) but also in the direction transverse to the belt axis. Conducting a series of scans of the St-type belt operating in one of the underground copper ore mines in Poland allowed identifying the number of failures as well as their size and changes over time. These data were in turn used to determine the measures defining the condition of the belt such as the density of defects (the number of defects per 1 m of the belt), the density of the area of damage (the area of damage per 1 m of the belt) and the change in the average area of a single defect over time. By determining the regression of these measures in time and the rate of damage development in both directions (along the axis of the belt and across the belt), it was possible to forecast future states of the belt, as well as to evaluate the costs of different belt replacement strategies and the economic rationalization of the decision to replace them. This research has become possible owing to the development of the DiagBelt system for two-dimensional imaging of the damage to the core of steel-cord belts with resolution sufficiently high to allow tracking the development of single core defects.

“…The results of finite element analysis is influenced significantly by the finite element mesh. An inadequate mesh may cause serious mistake in our calculations (Fedorko et al, 2016). To get reliable results an appropriate mesh is needed, but it is usually quite complicated.…”

Thanks to 3D CAD modelling software the role of sections has been grown significantly. In this article we discuss the increasing role of sections. First we present some practical applications such as a section of a track and wheel and we also show how they can be used for mechanical calculations through an example of a shaft weakened with a keyway. The principle of additive manufacturing is also based on sections. Finally sections can be also used at optimizing parts, but in this paper we discuss only the case of shape optimizing.

A conveyor belt is one type of goods transportation in technological processes, particularly in the mining industry. The belt is the important material and principal part of the conveyor belt. The overall quality of the conveyor belt as its service life and impact loads are very important factors. Therefore, the purpose of this paper is to classify the types of impact damage that may occur in rubber-textile conveyor belts. In many works, many types of conveyor belts are tested at various levels and the type of impacting material. The level of damage occurred is investigated by using probability theory. Particularly, the evaluation of experimental test data and predictive modeling is carried out using the Naïve Bayes classification.
