  • Dry and Wet Screening in Mining: What are the Differences ...

     · The Benefits of Dry Screen Processing More economical by design, standard screening solutions rely on vibrational energy and gravity. If the high-volume aggregate goes up, its mass will inevitably bring the fine grains down again. Energetic impacts separate the material so that it can be sized and sorted.

  • P&Q University Lesson 9

     · The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings. Where cleaner aggregate materials are required, cross dams and sprays can be included to assist with the washing process, liberating fines that pass through the media.
