In ironmaking and steelmaking, binders must have low silica, low ash, high environmental sustainability, and compatibility with furnace lining and slag. Gelatinized corn starch has shown good performance with several residues (e.g., jarosite, red mud, mill scale), but it has not provided consistent results when used with integrated steel-plant by-products. This study investigated the possibility of replacing corn starch with Arabic gum, analyzing briquettes produced from basic oxygen furnace dust combined with two reducing agents: blast furnace sludge (BFS) and secondary dust (SD). Arabic gum improved impact resistance index of BFS-containing agglomerates reaching IRI of 1000 (125 with starch), due to better particle arrangement and densification. The resulting lower porosity (34.3 % Vs 39.3 %) enhanced contact between carbon and iron oxides, raising the reduction degree to 90 % (86 % with starch). Moreover, the denser microstructure limited the swelling phenomenon observed in starch-bound briquettes during thermal treatment. In contrast, the use of SD as the reducing agent resulted in a coarser particle size, leading to a heterogeneous distribution during the mixing process with Arabic gum. This corresponded to a decrease in mechanical stability, with the briquettes surviving 5 drops compared to 10 with starch. Despite this drawback, the degree of reduction remained largely unaffected at 1200 °C.</div></div>","PeriodicalId":401,"journal":{"name":"Particuology","volume":"110 ","pages":"Pages 96-108"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146024978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many studies report tumbling in idealized systems with spherical particles, the physical origin of this motion remains unclear, especially when the density difference between the particles and the fluid is small. In this work, we revisit the classic DKT configuration using a fully resolved CFD–DEM model based on the immersed boundary method. Our analysis systematically examines whether the observed tumbling is a genuine physical phenomenon or a numerical artifact. Our results indicate that, in the absence of real world imperfections such as surface roughness or shape irregularities, tumbling is primarily caused by numerical errors rather than inherent flow instabilities. This finding challenges the conventional interpretation of DKT as a purely physical benchmark and highlights the need for caution when using tumbling to validate CFD–DEM models. By distinguishing numerical artifacts from physical effects, this study provides new guidance for model validation and has important implications for extending CFD–DEM to dense particle systems.</div></div>","PeriodicalId":401,"journal":{"name":"Particuology","volume":"110 ","pages":"Pages 131-143"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146074944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three-dimensional morphology of wheat kernels was obtained using X-ray micro-computed tomography, and multi-sphere models were constructed for particle representation. Parameter calibration was conducted in two steps: first, contact parameters were determined through angle of repose experiments and corresponding DEM simulations; then, breakage parameters were calibrated based on single-kernel compression tests. The results showed that the simulated angle of repose was highly consistent with the experimental values, with a relative error of about 1.9%. Compression simulations successfully reproduced the fragmentation patterns and force–displacement responses observed in experiments, with errors of less than 5% across different kernel morphologies.
