Pulper rags are a very tightly entangled mechanical compound of metallic and non-metallic components formed during pulping of recovered paper or pulp in the vortex center of a pulper.
ANDRITZ MeWa will supply a two-stage process for treatment of the pulper rags. In the first section of the plant, the rags will be pre-shredded using the Universal Rotary Shear UC 1300. The slowly rotating, twin-shaft cutter unit is excellently suited for powerful and, at the same time, 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 in the UG 1000 S granulator. By using a replaceable screen with variable screen slot diameters, the customer is able to influence the throughput and the shred-ding result. At the end of the process, the metal fractions produced have a high purity level. The residual fraction is used as substitute fuel.
The convincing results obtained in extensive material tests in the test center at ANDRITZ MeWa's headquar-ters in Gechingen, Germany, were decisive in placing the order with ANDRITZ MeWa, in addition to the higher throughputs obtained compared to competitors' equipment.
Papier- und Kartonfabrik Varel was established in1947 and is a medium-sized, family-run company. With more than 500 employees at its location in Varel, the company produces 850,000 tons per year of high-grade paper and board on four production lines as raw material for the packaging industry.
