A vibration grader is a specialized machine used in various industries, primarily in agriculture and food processing, to sort and grade materials based on size, shape, or other physical characteristics using vibration and gravity. These machines typically feature adjustable settings for vibration intensity and frequency, an inclined surface for material flow, and screening components to separate materials into different grades or sizes. Vibration graders find applications in agriculture, food processing, mining, recycling, and more, enabling precise sorting and grading of various materials to enhance product quality, reduce waste, and improve processing efficiency.
