Cleaner reFiner ProteCtion world pulppaper32 DUALXCLUDER installation the machines continue to run trouble free with very little operator attention required Recently a European tissue mill installed two DUALXCLUDER screens on separate lines to protect refiners. The tissue mill had previously experienced repeated damage to the refiner fillings from contaminants in the process mainly pieces of tile and baling wires. Both DUALXCLUDER screens were commissioned in October 2014. The DX Model 2025 processes slightly more than 1000 lpm of 3 consistency pulp with a 0.1 bar pressure drop and 50 motor load 5.5kW motor. The DX Model 3035 processes nearly 2000 lpm of 4 consistency pulp with a 0.1 bar pressure drop and 50 motor load 7.5kW motor. Both DUALXCLUDER screens started up troublefree and the removal of tramp materials could be observed following the first flush sequences. The machines continue to run trouble free with very little operator attention required. Sdra Cell Vr in Sweden installed two DX Model 4050 screens to protect the new approach flow cleaners installed as part of their 2011 bleached softwood pulp line upgrade. The machines are situated in parallel because of the high flow required but discharge intermittantly into a common reject trap. Due to the long fibres for this particular application GLV supplied a patented diamond pattern screen cylinder. The machines continue to operate successfully. In 2013 two additional DX Model 4050 screens were delivered for the upcoming capacity expansion of the mill. ConClUSion The DUALXCLUDER technology has proven to be a small footprint low energy solution to problems faced by pulp and paper mills with tramp material contamination such as baling wire. The pressure drop across the unit is minimal making it possible to install the screen into existing lines with very few changes required. In most cases a single unit can handle full production. GLVs innovation programs focus on energy and capital cost reduction in both equipment and process system designs. Their innovations where possible are designed to be retrofitted into older equipment as well in order to reduce investment cost and for sustainability. CaSe StUDieS
