Sand Classifiers

General Kinematics sand classifiers sort sand by grain size. Classifiers separate sand by grades, remove dust, and discard waste sand. The remaining “good” sand is distributed by grain size, then can be discharged to be remixed into the AFS required for your process. Air flow is recirculated, reducing bag house requirements.


  • Classifies granular materials based on size and density.
  • Provides a product distribution from a metered flow.
  • Multiple discharges allows for product to be re-mixed into whatever AFS required.
  • Heavies and lights can be removed from the material stream.
  • Air is recirculated, requiring minimal bag house or permitting.
  • Can be paired with Sand Cooling and screening.
