“…To better understand which parts of the forest residue will be responsible for the size reduction tool wear, the wear properties of individual anatomical fractions of forest residues were investigated using a blasting wear tester and were correlated with their chemical and mineral profiles . Another effort attempted to study the ash-tool abrasion using a dry sand/rubber wheel test (ASTM-G65) . In addition to field experiences and laboratory experimental studies, some modeling efforts have been made to estimate and predict the ash-induced tool wear for the hammer mill and the tillage tool…”

The importance of size reduction to the commercial deployment of biomass utilization technologies cannot be overemphasized. Size reduction is necessary to create good flowing, easily digestible lignocellulosic biomass. However, inefficiencies and inconsistencies have not been well addressed for the process of size reduction. This has motivated quite a few research studies, some of which have reported the influence of process variables and pretreatment on the size reduction performance as well as the development of novel size reduction equipment and empirical mathematical models. In this Perspective, we present a systematic and critical evaluation of the state of lignocellulosic biomass size reduction research to provide insights for engineers and scientists for future development and investigation. We first briefly discuss the structural biology and failure mode of lignocellulosic biomass. Then, we present a comprehensive, data-driven picture of the interactions among lignocellulosic biomass attributes, size reduction process variables, pretreatment processes, and size reduction process performance (as defined by product characteristics and size reduction energy consumption). The sizing equipment tool wear issues are also summarized. Finally, we highlight some existing gaps and future research opportunities for lignocellulosic biomass size reduction to inform the development of newer technologies that could effectively produce high-value lignocellulosic biomass particles.

“…Співвідношення між цими процесами визначають інтенсивність абразивного зношування. В результаті раніше проведених досліджень [1,2,3,4,5] встановлено, що при зношуванні робочих органів ґрунтообробних машин механічні процеси на поверхні тертя переважають над іншими і визначають механізм та інтенсивність зношування. Вибір матеріалу робочих органів ґрунтообробних машин повинен ґрунтуватися на властивостях ґрунтового середовища, що будуть визначати механізм абразивного зношування [6].…”

“…The amount of these abrasives in the soil significantly affects the materials' wear rate. The research results of Chotěborský [11] and Hoormazdi et al [12] show that the soil contains minerals that are harder and sharper in shape than sand. Its hardness may be 2-5 times that of metal particles.…”

The abrasive wear characteristics of 40Mn2 steel be studied in this paper. The rubber wheel abrasive wear tester be used for simulating the sprocket wheel working-conditions. The relationship between worn surface residual stress and wear rate was studied. Wear surface morphology and mechanism worn surface micro-structures are also shown in results. In addition, there are XRD pattern of the experimental abrasives, to better reveal the abrasive wear mechanisms. The results indicates that the larger the applied load and sliding speed is, the greater the wear rate will be. The content of hard phase in abrasive determine the wear rate. The main wear mechanisms of soil and coal in workingconditions are scratching and spalling, respectively. Spalling, chipping, scratching and pitting are the main wear mechanisms in sand working-condition. There are same trend of the wear rate and the worn surface residual stress with the wear time increasing. Intergranular carbides can decrease the wear resistance to some extent.
