High Frequency Sizing Screens - 911Metallurgist

Screening is the process of separating particles by size and fine screening typically refers to separations in the range of 10 mm (3/8″) to 38 microns (400 mesh). Fine screening, wet or dry, is normally accomplished with high frequency, low amplitude, vibrating screening machines with either elliptical or straight-line motion.
