Fine powders are very small particles that can be created from various materials, such as minerals, metals, or food products. These powders are often used in industries like pharmaceuticals, cosmetics, and food processing. Their small size allows for better mixing, faster reactions, and improved texture in products. The production of fine powders typically involves processes like grinding, milling, or atomization. For example, talc is a fine powder used in cosmetics, while flour is a fine powder made from ground grains. The properties of fine powders, such as flowability and particle size distribution, are crucial for their performance in different applications.
