A sand screening machine is equipment designed to separate sand or similar materials by particle size, commonly used in construction, mining, and agriculture. Its primary purpose is to classify mixed materials into different fractions (fine, medium, coarse).

How Does It Work?

  1. Feeding: Mixed sand is fed into the machine via a hopper or conveyor belt.

  2. Vibratory Screening: A vibrating motor or mechanism shakes the screen (perforated metal or mesh), causing the sand to move across it.

  3. Size Separation: Fine particles pass through the screen openings, while larger particles remain on top.

  4. Collection: Separated sand fractions are collected from different discharge outlets.
