Andritz offers recycling plants for pulper rags and rejects
Andritz, Gratz, Austria, points out that waste paper is usually delivered to paper mills in pressed bales held in shape by wires. The stock preparation process generates rags that comprise wires and other rejects which are all those materials that are not paper, such as plastics, textiles and metals.
Depending on the requirements, Andritz MeWa systems include several shredding stages in order to break down the stubborn rags properly. The robust machine technology with its very hard wearing cutting gear releases the metals (accounting for up to 40% of the content) completely.
Impurities are separated into different fractions by subsequent separation processes. The calorific materials are further processed to provide substitute fuels.
In addition to the pulper rags, other rejects include: loose pulper rejects containing mainly plastics, metals, stones, wood; sand-containing cleaner rejects; lightweight rejects from the coarse screening.
Andritz says that the benefits of its recycling systems for pulper rags and rejects include: Applied process knowhow from the company to ensure minimized operating costs with highly efficient process equipment; single customer interface – entire system, all subprocesses and components from one source; modular system designs which allow tailor-made solutions for the specific waste streams; highest cutting performance and capacity of the shredders.
Other features include: extremely wear-resistant rotor, blade blocks and blades; adjustable parameters for influencing the output quality and size; clean output fractions.
