Segregation is an important process mainly used in industries during the flow of granular materials. A granular medium is repeatedly collected particles that have different properties like size, shape, and density. Heap formation in the industry occurs if particles with various sizes, forms, material densities or surface properties are made of bulk materials, then they spatially separate during formation of the heap. This paper provides a detailed understanding of segregation dynamics in granular flows within industrial processes. Focusing on the intricate interplay of particle characteristics, mixing phenomena, and heap formation methodology, the review delves into the essential aspects influencing the spatial separation of particles. Granular media, comprising particles with distinct properties such as size, shape, and density, undergo segregation during the flow processes commonly employed in industries. The formation of heaps becomes a consequential outcome when bulk materials consist of particles exhibiting variations in size, shape, material density, or surface properties. The comprehensive analysis within this review encompasses detailed insights into granular material flow, the intricacies of mixing, the mechanisms of segregation, and the profound effects of particle characteristics on these processes. Additionally, the paper scrutinizes various methodologies employed in industrial settings for heap formation, providing a holistic perspective on the key factors influencing segregation dynamics in granular flows. This review aims to contribute valuable insights to researchers, engineers, and practitioners involved in the optimization and control of granular material handling within diverse industrial applications.
