This study experimentally investigated the impact of raw material moisture content and molding pressure on pellet performance. A grading index was introduced to characterize particle size distribution. The experimental findings demonstrated that the porosity of CBPs-RF was notably reduced from 17.3 % to 11.4 % when subjected to a grading index of 0.5. This substantial decrease in porosity was primarily attributed to the iron ore concentrate effectively filling the interstitial spaces among the coarser return fines, thereby enhancing the material's compactness. Furthermore, a composite binder tailored for sinter return fines was developed; organic binder B contains abundant polar functional groups, which facilitate chemical adsorption onto the surface of iron ore compounds, thereby ameliorating the contact heterogeneity between inorganic binder A and the return fines. The crosslinking reaction between organic binder B and inorganic binder A yields an interwoven three-dimensional network structure, underpinning the enhanced binding strength of the composite binder. Compared to conventional sinters, CBPs-RF demonstrated superior performance in low-temperature reduction degradation (RDI<sub>+3.15</sub> > 90 %) and reduction swelling index reduction (RSI < 10 %). Its advantages stem from the dispersed arrangement of sinter return fines and their effective synergy with soft binders and porous iron fine layers, mitigating crack propagation and expansion during reduction, thus alleviating volumetric expansion. Comprehensive burden studies indicate that incorporating 5.0 % CBPs-RF exhibits favorable softening and dripping properties, providing crucial insights for the efficient utilization of sinter return fines as a blast furnace burden.</div></div>","PeriodicalId":407,"journal":{"name":"Powder Technology","volume":"457 ","pages":"Article 120921"},"PeriodicalIF":4.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This not only reduces fracturing efficiency and damages equipment, but also generates solid waste. Due to the unclear understanding of the proppant flowback mechanisms, the control measures effectiveness is highly uncertain. This paper established a model that considers the synchronous changes of fracture closure and flow field based on the CFD-DEM. Numerical simulation research of near-well fractures including perforation was conducted. The results show that particles near and above the perforations are more prone to flowback. The critical fracture width to particle diameter ratio (<em>w</em>/<em>d</em>) for uniformly sized spherical particles is 2.55. Controlling the flowback velocity within the fracture to below 0.01 m/s allows the particles to form stable bridges. Non-spherical particles and particles with non-uniform diameters have less flowback and smaller changes in fracture width. For particles with non-uniform diameters, the minimum particle diameter is the main factor determining the particle flowback ratio. The more evenly the proportion of particles of different diameters is distributed, the stronger the ability of the proppant to resist the fracture closure. Particles with a larger size distribution range have a lower flowback ratio and a wider propped fracture width. Rod-shaped particles effectively resist the pressure of fracture closure, maintaining a larger fracture width. Perforating in the upper part of the reservoir, using low-viscosity fluids to reduce the near-well fracture width, filling the near-well fractures with large-sized, wide size distribution (such as 20/70-mesh) or non-spherical particles (such as rod-shaped proppant) could help alleviate the proppant flowback.</div></div>","PeriodicalId":407,"journal":{"name":"Powder Technology","volume":"457 ","pages":"Article 120913"},"PeriodicalIF":4.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving the permeability of the sintering packed bed can enhance sintering efficiency and reduce energy consumption. Among various technical measures, optimizing the operational parameters of granules chargers has proven to be an effective and straightforward approach. However, previous studies have not addressed a key issue: how to balance permeability with the overall sintering process performance. To address this gap, this study develops an eleven-roller charging model and employs the Discrete Element Method (DEM) to simulate and analyze granular segregation in the entire sintering process. The effects of operational parameters, such as roller speeds and angles, on segregation are systematically investigated. Cold-state permeability experiments are conducted to evaluate the permeability of granular packed beds, while high-temperature sintering cup experiments determine the optimal segregation level for superior sintering performance. Computational fluid dynamics (CFD) simulations further reveal that changes in bed porosity play a crucial role in sintering performance. The results indicate that reducing roller speed increases particle velocity differences, enhancing segregation and improving packed bed permeability. Adjusting the roller angle also significantly affects permeability. High-temperature sintering cup experiments show that, under present conditions, a segregation ratio of 5 % optimally balances permeability and sintering efficiency, and the vertical sintering rate increases from 16.5 mm/min to 19.2 mm/min, and productivity improves from 1.30 t/m<sup>2</sup>·h to 1.60 t/m<sup>2</sup>·h, significantly enhancing overall sintering performance.</div></div>","PeriodicalId":407,"journal":{"name":"Powder Technology","volume":"457 ","pages":"Article 120891"},"PeriodicalIF":4.5,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
