Bulk materials refer to materials that are stored, transported, and handled in large quantities. These materials are typically solid particles or granular substances such as minerals, grains, powders, and chemicals. Research in the field of bulk materials focuses on understanding the properties and behavior of these materials, as well as developing methods for processing, handling, and transporting them efficiently and safely. This research area often involves the study of aspects such as flow behavior, storage conditions, particle packing, segregation, and mixing processes. Applications of bulk materials research can be found in various industries including mining, agriculture, pharmaceuticals, and construction.
