Andritz has extensive experience processing furnishes such as OCC, AOCC, Liquid Packaging Board, Mixed Waste, etc.
These industrial grade furnishes typically have more contaminants, which must be removed early in the process before they have an opportunity to disintegrate into the stock. Andritz offers a range of application-matched processes and equipment for recycling industrial grades.
Key equipment
In addition to conventional pulping systems for industrial grades, Andritz recommends the FibreFlow® drum pulper in order to ensure high pulp quality. The FibreFlow® drum removes contaminants in the first stage of the process. In this way, the purity of the pulp is maximized and less equipment is required downstream to clean the pulp. The FibreFlow® drum itself does not generate fines or damage fibers. The best fiber qualities are maintained. In the next process steps, Andritz ModuScreen™ systems are employed to maximize pulp cleanliness. For certain furnishes and final pulp characteristics, Andritz installations are successfully operating without cleaners and dispersers. This translates into savings – in investment, maintenance and energy costs. If dispersion is needed, the Andritz CompaDis™ disperser with its innovative technology will be the right choice. Pulp thickening is easily and economically accomplished with Andritz thickeners. There are excellent Andritz solutions for handling rejects and sludge, as well as water treatment.
System integration
When developing components for each process step, we also develop the understanding of how individual equipment performs most efficiently in the entire system. As a result we have also been able to combine two process steps in a single unit. Hundreds of installations give us the foundation for suggesting improvements and modifying equipment for each new application.
Engineering
To work efficiently and with the highest quality, we mainly use our in-house engineering capabilities. We perform basic/detail plant and process engineering, 3D planning, electrical and control engineering, DCS programming and factory acceptance tests. Our ELDOC documentation system provides Erection-Operation-Maintenance (EOM) instructions on an intelligent CD-ROM – with database, user-friendly interface and search functions.
Project management, as well as supervision to turnkey installations
Our project managers are experienced and skilled in international project management. We have a history of success in completing first-class turnkey installations on time. Depending upon the level of support you need, we can supply services ranging from erection supervision, start-up and commissioning to complete turnkey – even EPC – responsibility.
