Key Equipment: The case for Conventional Thinking
ANDRITZ is regarded as an innovator in developing technologies for the manufacture of premium tissue grades that are in high demand today. Yet the majority of the world’s tissue is produced using conventional dry-creping techniques. To serve this large market, ANDRITZ continually enhances the reliability and performance of its “standard” technology.
FULL LINE OF DRY-CREPING SOLUTIONS
Today, ANDRITZ is among the top three tissue technology suppliers in the world and the number one supplier in China.
With this solid foundation, the company continues to improve the performance and cost-efficiency of its dry-crepe product technologies PrimeLineCOMPACT and PrimeLineTM which are available in a variety of widths and capacities:
- PrimeLineCOMPACT machines are ideal for producers who appreciate a standardized, modular approach that reduces engineering, transport, infrastructure, installation, and start-up costs. The COMPACT machine ensures a certain throughput and production quality in a streamlined, cost-effective package.
- PrimeLineTM machines are customized high-speed machines with widths from 2.6 to 5.6 m. Like the PrimeLineCOMPACT, they can be equipped with a shoe press, a steel Yankee (diameters up to 26 ft) and ANDRITZ Novimpianti air and energy systems that help to improve yield, efficiencies, and energy conservation.
Proven ANDRITZ technologies in stock preparation, such as ShortFlow approach technology and the Papillon refiner, contribute to the economical use of resources and superior performance in conventional tissue applications. ShortFlow minimizes the amount of equipment and the amount of energy consumed, saving on both capital and operating costs. It requires very low, but efficient, storage volumes to reduce the size of tanks and allow for fast grade changes on the machine. For refining, the Papillon refiner has a compact cylindrical rotor design. Energy savings can be quite significant when compared to competitive refiners, and the fiber is properly treated over the entire refining area.
One of the more recent innovations in stock preparation, the PrimeScreen X, improves energy consumption, screening efficiency, and ease of maintenance. This new screen has a top feed stock inlet and a new PrimeRotor configuration with new rotor foils to offer unique benefits.
Machine and mill automation are addressed through ANDRITZ Automation’s Metris technologies for digitalization, simulation, and overall optimization. Smart Solutions for tissue producers include, but are not limited to, automation technologies for predictive maintenance, the Metris UX Platform, Metris Smart Service including the Metris Spare Parts Catalog and Metris OPP (Optimization of Process Performance).
INNOVATION AND PERFORMANCE
To further develop and support its technologies, ANDRITZ continues to make investments in the PrimeLineTIAC. The tissue pilot plant is available to all tissue producers and suppliers worldwide, and also to partners and institutions within the tissue value chain. For example, the latest machine design, PrimeLineTEX, was developed and tested at the tissue pilot plant. It enables the production of premium textured tissue with a quality very close to TAD. The PrimeLineTEX tissue machine is of utmost flexibility: it can be configured as a “pure” textured machine or as a machine that can produce either dry-crepe or textured tissue.
