Bulk solids are materials that consist of a large quantity of particles, such as grains, powders, or pellets. These materials are typically handled in large volumes and can be found in various industries, including agriculture, mining, and construction. Bulk solids can vary in size, shape, and density, affecting how they flow and behave during processing. The handling and storage of bulk solids often require specialized equipment, such as conveyors, hoppers, and silos. Understanding the properties of bulk solids is essential for efficient transportation and processing, as factors like moisture content and particle size can influence their performance in different applications.
