screening machine for small particle

DiamondRoll® Particle Screens - Acrowood

This screen has larger diameter shafts than the typical fines screening version. As a result, materials spend more time in the nip, leading to better screening of small particles. The roll surface patterns are often smaller and the Inter-Roll Opening has tighter spacing to accommodate the sorting of small and fine fractions.
