Dewatering Screens McLanahan

The smallest aperture on a Dewatering Screen is typically 50 mesh 0.3 mm, so you will expect to see some of that size fraction and finer in the underflow of the screen. Not all of that fraction will pass through due to the very nature of caking style screens fines are captured in the bed formed on top of the media.
