Particle size reduction is the process of breaking down larger materials into smaller particles. This is commonly achieved through various methods such as grinding, milling, or crushing. The goal is to increase the surface area of the material, which can enhance its reactivity and improve its performance in applications like pharmaceuticals, food processing, and materials science. In industries like pharmaceuticals and food processing, particle size reduction is crucial for ensuring uniformity and consistency in products. Smaller particles can dissolve more quickly, leading to faster absorption in the body or improved mixing in food products. This process is essential for optimizing the effectiveness of many materials.
