Size reduction is the process of breaking down materials into smaller pieces or particles. This technique is commonly used in various industries, including food processing, pharmaceuticals, and mining. The goal is to improve the material's properties, such as increasing surface area for better reactions or making it easier to handle and transport. Methods of size reduction include mechanical processes like crushing, grinding, and milling. These techniques can be applied to different materials, such as grains, minerals, and pharmaceutical compounds. By reducing size, manufacturers can enhance efficiency and optimize production processes.
