To meet the performance challenge of rejecting overthick chips without also rejecting acceptable chips, Disc Thickness Screen is a good solution. This configuration provides effective chip mat agitation, achieving both high overthick removal and low accepts carry-over. Disc Thickness Screen Features Excellent chip agitation provides quick passage of fines and small chips Effective overthick removal efficiency with high throughput in a relatively small footprint Heavy-duty design uses wide-flange beam sub-base Bearings protected from contaminants with placement of pillow-block bearings mounted outboard of screen hopper walls Discs are installed to shafts for excellent screen accuracy and high strength shaft construction Minimal maintenance a result of robust, sintered bushing chain drive with hardened sprockets. No sealed oil bath or periodic lubrication required! Discs means more selective overthick chip screening. Application Highly selective thickness screening is achieved by efficiently rejecting the overthick chips without also rejecting acceptable chips. Disc Screen: its configuration provides effective chip mat agitation, achieving both high overthick removal and low accepts carry-over, resulting in maximized chip yield, chip quality and chip uniformity. Helping to maximize efficiency, quality and cost effectiveness of your entire pulping process. Disc Screens process chips differently than any other thickness screening method, and that’s why they do more complete and selective job of chip thickness separation. On the Screen, chips travel across alternately elevated shafts in a sinusoidal path. This non-linear path “breaks” the chip mat, increases chip agitation and dwell time, while its spreads the chip feed evenly along the full shaft length. All these factors enhance screening performance. In addition to the selective separation of overthick chips, the Disc Thickness rapidly segregates and concentrates pin chip and fines, reducing the amount of screening area required for secondary processing.
