Abstract
This study presents the results of a comprehensive study on various agglomeration methods and binder types for producing briquettes from raw materials. Also, this research focuses on one of the major issues in the production of extrusion briquettes, namely their mechanical strength during handling, transportation, and water exposure. Laboratory experiments were conducted to identify the most suitable binding agents, followed by industrial-scale trials of several formulations. The paper also includes the results of pilot-scale tests. Four types of binders were examined: bentonite, TD 021.005.BS, TD 000.411.BS, and TD 000.414.BS. The strength characteristics of the briquettes were evaluated in accordance with the relevant GOST standards: GOST 21289-75 for hot strength, GOST 25471-82 for drop strength, and GOST 15137-77 for impact and abrasion resistance. The findings indicate that, from a technological perspective, the most efficient binder for briquette production is TD 021.005.BS, when applied within the range of 2.5–3%. Notably, briquettes produced with this binder demonstrate superior moisture resistance compared to other formulations. After 24 h of immersion in water, they retained their original shape and structural integrity, confirming the binder’s high effectiveness for industrial applications.
