Screening Theory and Practice - Triple/S Dynamics
Allowable surface moisture for unimpaired dry screening of inorganic granular or pelletized particles ranges from dry for screen openings below 20 mesh, to 3% for 1/4" openings. Absorbed moisture in permeable soils such as ground clay can block the screen openings with cumulative buildups of extreme fines attached to the screen wires.
