“…Such description will facilitate the assessment, on the basis of the observed damping, of how a conveyor belt is able to damp the material bouncing on the conveyor belt so that no serious damage is caused to the conveyor belt. Table 3 Estimates of the regression model parameters (12).…”

“…Analysis of the conveyor belt wear, in terms of impact loading during the interaction between the support system and the conveyor belt, has been described by many authors in experimental papers [9,12], but it has never been transformed into a standard. One of the first papers dealing with the experimental research of the conveyor belt resistance to impact loading is the paper by Köttegen [13] in which the author conducted the registration (of the record) of impact force pulses and documented that belts supported by another belt at the impact (filling) point have stronger ability to absorb the impact energy, compared to belts supported by idlers.…”

“…The precipitation of elements increases the hardness of the padding weld and increases the abrasive wear resistance of whole surface element. Based on the results of the surface roughness profile and its topography, it can be concluded that the abrasive wear could occur according to the three-body modes [ 28 , 44 ]. Molnar et al [ 36 ], while testing the conveyor belts, found that during the ASTM G65M test, a three-body abrasion mechanism based on the fatigue occurs.…”

Elements of belt conveyors, like other machine parts, are subject to wear processes. The conveyors transporting the spoil in the quartz sand mine are exposed to accelerated wear due to the effect of quartz on metal elements. Intensive wear of metal parts leads to downtime and the need to replace damage parts which generates additional costs. Therefore, it is important to perform surface treatment of metal elements, which will allow to extend the operation time of belt conveyors by reducing wear. The main objective of the article is to determine the impact of the pad welding process of the surface layer of metal elements on the abrasive wear of elements working in the metal–quartz sand–rubber conditions used in belt conveyors. In this research study, three different types of electrodes were used for pad welding the surface. The wear results obtained on the test stand were compared to wear of the basic element without surface treatment. The average wear value of the samples padded with electrode 3 was about 25% lower than the samples without surface treatment. The main mechanism of sample wear was the abrasion process due to the interaction between the steel surface and hard sand particles. The results presented in the article are important not only for belt conveyor elements but also for other machine parts where it is desirable to reduce abrasive wear.

“…The differences range from the idler's design and material to its rolling bearings, sealing system, and grease types. Idlers roll materials, more specifically the replacements of steel idler rolls for polymeric ones, have been a topic of significant interest for two main reasons: (i) steel rolls are heavy and their replacement in the field might lead to injuries to the maintainers; (ii) the in situ abrasion, due to the contact between the idler rolls with the conveyor belt in the presence of foreign particles, leads to the formation of sharp edges on the worn idler roll that might cut the conveyor belt, causing significant economic losses [4]. This situation, in general, occurs due to bearing failure, which halts the idler roll motion leading to severe wear.…”

Idler rolls are an integral part of belt conveyors. Even though idlers have been developed to perform adequately for various installations over the years, selecting the most appropriate one is not that clear. Idlers roll materials, more specifically the replacements of steel idler rolls for polymeric ones, have been a topic of significant interest. However, the use of polymeric material brings other challenges, in particular, presenting similar structural and abrasion resistance to steel. This works proposes a methodology using a rubber-wheel tribometer to evaluate the abrasion resistance of polymeric idler rolls in their most severe operating condition (halted idler roll) and defines a threshold limit based on the results obtained with steel idler rolls. The methodology was applied to 07 different polymeric materials. Aiming further understanding of materials abrasions resistance, scratching tests were performed, and the main wear mechanisms, verified by scanning electron microscopy (SEM) and abrasion factor (fab), were discussed along with the material properties and wear. The main conclusions were that some polymeric materials present abrasion resistance similar to steel rolls. The wear micromechanisms, verified by SEM and fab, are good indicators of abrasion resistance of the materials, but insufficient because they do not include fatigue effects resulting from multi-events and the additive fillers studied significantly altered the abrasive resistance of materials.
