The DiamondRoll VIRO Fines Screen typically separates more than 90% of fines from usable pin chips at high production rates, saving 70% to 90% of the valuable fiber rejected by other screening methods.

• The solid alloy steel shafts are machined for a surface topography that briskly moves the chips from the inlet to the discharge
• This high opening accuracy is the key to operating the screen for maximum possible efficiency
• Using solid, alloy steel shafts as the base material for the rolls helps to maintain the straight and constant opening
• Textured rolls with application-specific patterns set the base selectivity for one type of fines over another
• Improved chip recovery and quality
