“…The wear results obtained are consistent with those available in the literature [ 6 ]. Su et al [ 30 ] showed that the shape of the element working in the ground and the material it is made of affect its service lifespan and the reliability of its use. In addition, intense abrasive impact of the sand particles was found on the surface of the worn parts, similar to past studies [ 2 , 39 ].…”

“…There are a number of wear testing methods that include: the pin-on-disk tests [ 25 ], abrasion tests on laboratory stands [ 26 , 27 ] as well as wear rate measurements in laboratory and field conditions [ 28 ]. For the latter group of studies researchers quantify the wear rate by measuring the mass loss [ 29 ] or volume loss [ 30 ] of the tested sample over a specific duration. This allows for comparisons between different materials, coatings or experimental conditions.…”

Renovation of dirt roads requires a reliable and durable work tool. This article includes the methodology of field and bench tests as well as the results of these tests and conclusions for cutters used for dirt road renovation. The main novelty of the research presented in this article was to determine the wear mechanisms occurring during field and laboratory tests, to determine the differences in wear levels and the cost of renovation of one kilometer of dirt road. Calculations of the efficiency of replacing these working elements and the cost of operating various cutters per km are also presented. The lowest mass loss was characterized by milling cutters Ø25 mm mounted on an expansion sleeve and amounted to 130 g. The dominant wear mechanism that was observed after the renovation of dirt roads was micro-scraping and micro-bruising. For this variant, the cost per 1 km of road renovation was also the lowest and amounted to about PLN 2.

“…The structure and operation principles of this system are discussed, and a detailed analysis of its key components and working process is provided. Su et al [4] aim to address the problem of the arc-shaped nail tooth, a key component in pre-sowing film recovery machines, being prone to wear and fracture deformation. However, mechanically recovered film residues contain a large number of impurities, making it difficult to reuse the recovered film residues.…”

A tumbler screen-type residual film–impurity mixture wind separator is the key equipment for the secondary utilization of farmland residual film. During its operation, the proportion of impurities in the separated waste mulch film intermittently increases, resulting in poor working stability of the device, which may hamper long-term operation. To address the above issues, the material inside the separation unit was continuously monitored, and the main factor affecting separator performance was determined to be the challenges in the effective depolymerization of some residual film-impurity mixtures. The principles of agglomeration and depolymerization of the residual film-impurity mixtures were analyzed using computational fluid dynamics (CFD) and discrete element method (DEM) flow-solid coupling simulation methods. The key factor affecting the disaggregation of the mixture was the collision force between the residual film–impurity mixture and the trommel screen. The collision force was maximum when the residual film–impurity mixture first collided with the trommel screen when it was fed into the separation device. Furthermore, simulations were carried out for different inlet structure forms; the evaluation index was the maximum collision force of the residual film–impurity mixture agglomerate on the trommel screen. The best disaggregation effect was obtained with a square feed inlet and at a feeding rate of 202 kg/h. A prototype was built using these specifications for verification. The average value of the ratio of impurities in the residual film was 6.966%, the coefficient of variation was 7.38%, and the dispersion of statistical results was small. The ratio of impurities in the residual film was kept constant during the continuous operation of the wind separator. Thus, in this study, we analyzed the agglomerate disaggregation process and provided theoretical insights for determining the optimal structures of the inlets of various cleaning devices and the feeding volumes.
