Abstract

Conducting realistic wear tests on the middle plates of scraper conveyors is challenging.

This paper uses middle plate wear as an example to introduce a versatile abrasive wear test device. The device considers frictional relationships and motion forms between mechanical structures to replicate actual conditions and allows for single-factor comparative analysis.

Using this test device, orthogonal testing was conducted to establish that the abrasive hardness are the principal determinants of wear. From the perspective of three-body wear, the rationality of rock pretreatment to reduce wear was verified. An optimal abrasive particle size was identified that minimizes wear, and two novel methods were proposed to reduce the wear of the middle plate. A predictive model for middle plate wear was developed with limited test data, showing that R² and R²_adj are above 89 %. A tool was provided to facilitate the rapid development of materials with enhanced wear resistance.

This study provides tools and theoretical guidance for investigating wear mechanisms and enhancing material wear resistance.

刮板输送机中间板磨料磨损试验装置的设计与评价

对刮板输送机中间板进行真实磨损试验是一项具有挑战性的工作。本文以中板磨损为例，介绍了一种多功能磨料磨损试验装置。该装置考虑了机械结构之间的摩擦关系和运动形式，以复制实际条件，并允许单因素比较分析。利用该试验装置进行正交试验，确定磨料硬度是影响磨损的主要因素。从三体磨损的角度，验证了岩石预处理降低磨损的合理性。确定了磨损最小的最佳磨粒尺寸，并提出了两种减少中间板磨损的新方法。利用有限的试验数据，建立了中板磨损预测模型，结果表明，R2和R2adj均在89%以上。提供了一种工具，以促进具有增强耐磨性的材料的快速开发。该研究为研究磨损机理和提高材料耐磨性提供了工具和理论指导。

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
