A vibratory sieve is a mechanical device used to separate materials based on size. It consists of a mesh screen that vibrates, allowing smaller particles to pass through while larger ones remain on top. This process is commonly used in industries such as food processing, pharmaceuticals, and mining to ensure product quality and consistency. The vibration is typically generated by an electric motor or an eccentric weight, which creates a circular or linear motion. Vibratory sieves can be adjusted for different frequencies and amplitudes, making them versatile for various applications, including the separation of powders, granules, and liquids.
