Centrifugal machines are devices that use centrifugal force to separate materials based on their density. They typically consist of a rotating drum or bowl that spins at high speeds, causing denser materials to move outward while lighter materials remain closer to the center. This principle is commonly used in various applications, such as in centrifuges for separating blood components or in separators for clarifying liquids. These machines are essential in industries like pharmaceuticals, food processing, and chemical engineering. By efficiently separating mixtures, centrifugal machines help improve product quality and streamline production processes, making them vital tools in modern manufacturing.
