[0002] A vibrating screen is a high-precision fine powder screening machine. It uses a motor to generate forced vibration, causing the material to rotate and advance across the screen surface, achieving both separation and sieving. Its compact size, light weight, low noise, and high efficiency make it widely used in industries such as metallurgy, pharmaceuticals, food, and chemicals. For example, rice processing requires a vibrating screen for screening.
