Operational factors influencing quality control in ore milling: a systematic review

Abstract

Quality control in ball mill operations in the ore industry is crucial for ensuring the final product's quality and the equipment's efficient operation. Despite its relevance, there is a scarcity of studies on this topic. This bibliographic study, based on the PRISMA protocol, involved scientometric and qualitative bibliographic analysis. The analysis revealed that the topic is rarely addressed in the literature, resulting in a limited portfolio. The identified studies explore advanced techniques such as algorithms and mathematical modeling to optimize the grinding process and improve product quality. Research also discusses advanced control systems to ensure compliance in mill operations, leading to reduced variability in material granulometry, energy savings, and increased production. Furthermore, contributions include implementing virtual sensors to monitor cement fineness in real-time, optimizing operations, and enhancing the final product's quality. However, there is a notable lack of research focused on the particle separator, a crucial component in the grinding process. These findings provide valuable insights for the effective management and operation of ball mills in the mining industry and underscore the need for future research to address these gaps.
