The results of the tests indicate that PM4 crystalline silica emissions range from 0.000006 to 0.000110 lb/t for screening operations, tertiary crushers, and conveyor transfer points. The PM4 crystalline silica emission factors were proportional to the crystalline silica content of the material handled in the process equipment.

The panels are specially designed for an extended life cycle with the abrasive silica sand. Material enters a feed box and then falls onto the screen's surface, which is mounted on a downhill angle close to the angle of repose of the silica sand. This promotes better particle separation and high speed screening.
