Fine screen DiamondRoll®

DIAMONDROLL® FINES SCREENS This screen makes finite separations of smaller chip fractions. It typically removes more than 90% of fines from accepts and can retain or reject pin chips, as desired. Filtering chips to the correct size minimize the use of chemicals needed in the digester in the making of pulp. DiamondRoll Fines Screen Features The advantages of a DiamondRoll® screen include: •Highly efficient and selective fines removal •Low maintenance costs and downtime, •Excellent fiber recovery •Quick payback on good fiber recovery from waste streams. •Screening targets met and specific fines fractions segregated with various knurl patterns •Minimal fiber loss in non-blinding operation with special shaft design and tight gap settings •Low profile screen frame for simple installation •Obtain a higher yield of pulp from raw materials coming in, resulting in immediate savings A proven concept in high-efficiency fines screening Acrowood was the first in the world to bring roll screens to the industry. Today hundreds of DiamondRoll Fines Screens are in operation world-wide, helping mills retain valuable fiber while removing fines. Applications •Chip Plants •OSB Plants •Pellet Plants •Pulp Mills •Sawmills •Shavings Mills Success Is In The Rolls Chips travel across a series of parallel, rotating rolls machined from solid alloy steel. As these diamond-patterned rolls rotate, fines migrate into the space between the diamond tips and are rejected through the Inter-Roll Openings (IRO).
