Pulper rags processing line ordered by Papier- und Kartonfabrik Varel


line for pulper rags from Andritz MeWa, which is part of the Andritz group. Pulper rags are a tightly-


P


entangled mechanical mixture of metallic and non-metallic components formed during pulping of recovered paper or pulp in the vortex center of a pulper. A two-stage process for


treatment of the pulper rags will be supplied. In the first section of the plant, the rags will be pre-shredded using a UC1300 Universal Rotary Shear. The slowly rotating, twin-shaft cutter unit is said to be highly suited for powerful and energy-saving pre-shredding of the stringy input material and is largely insensitive to potential impurities. In a second step, the


material is shredded further 3


high effective storing density of around eight tonnes per square metre. Material flow capacity with fully automated in-out handling and sorting with two stacker cranes is 900 tonnes per hour. The TransRoll ARW system is equipped with Pesmel WMS warehouse management, which is connected to the mill information system to track the roll flow and to keep the real-time storage inventory for


the converting and shipping operations. Pesmel’s roll-handling system includes a large connecting conveyor system to a new high- capacity kraft wrapping line, with robotised core plugging and head insertion. The handling capacity is set to 120 rolls per hour, with the facility for an increase of 20-40 per cent in future. With automated truck loading, unpacked rolls are transported


from the TransRoll warehouse to the coating mill located one kilometre away. The rolls are loaded and unloaded automatically in horizontal position, which eliminates end damage to the rolls. Transferring the rolls unpacked generates remarkable savings to packing costs, says Pesmel. Also included is a custom-


tailored Pesmel FlowCare portal. This digital ‘internet of things’ interface collects, saves and


apier- und Kartonfabrik Varel in Germany has ordered a processing


in a UG1000S granulator. By using a replaceable screen with variable screen slot diameters, the customer is able to influence the throughput and the shredding result. At the end of the process, the metal fractions produced have a high purity level. The residual fraction is used as substitute fuel. Convincing results were


obtained in material tests at Andritz MeWa’s headquarters in Gechingen, Germany, and were decisive in placing the order, in addition to the higher throughputs obtained compared to competitors’ equipment. Founded in 1947, Papier- und


Kartonfabrik Varel is a medium- sized, family-run company, with more than 500 employees at its location in Varel. Each year it produces 850,000 tons of high-grade paper and board on four production lines as raw material for the packaging industry.
