The rebuild aims to increase PM 1's production of containerboard by about 19 percent to 128,000 tons of saleable paper per year, improve overall machine efficiency and reduce steam consumption.
Nov. 26, 2024 - Voith announced that it will perform a paper machine rebuild on PM 1 at Hinojosa Packaging Group's paper mill in Alquería, Spain.
The project aims to increase the machine's production of containerboard with basis weights of 115 to 195 g/m2 by about 19 percent to 128,000 tons of saleable paper per year, improve overall machine efficiency and reduce steam consumption.
According to Voith, the rebuild includes upgrades to both the OCC stock preparation and the paper machine. Voith will make changes to the approach flow system and also relocate the existing headbox. The forming section will be optimized and will receive new dewatering elements.
"Innovative modifications in the press section will enable a higher dry content and thus significantly reduce specific energy consumption with increased production capacity," explained Philip Schnellinger, Process Technology Manager at Voith Paper.
The first dryer group will be converted to a single-tier configuration with DuoStabilizers to enable ropeless threading and better web stabilization. New direct drives ("silent drives") are planned for the entire dryer section.
In addition, new S-Stabilizers will be installed in the double-tier dryer groups of the pre-dryer and after-dryer sections. An additional dryer group with new EvoDry steel drying cylinders will also be installed in the pre-dryer section. Four additional EvoDry steel drying cylinders will be installed in the after-dryer section and the drying hood will be extended.
Voith's Prevo system will be used to transfer the paper tail quickly and safely from the after-dryer section to the reel. The existing reel will be relocated and equipped with a new reel spool magazine. Voith's QCS On.Quality system will be integrated to improve process and quality monitoring.
An extensive spare parts package as well as comprehensive engineering and services are also part of the scope of supply.
The shutdown and restart of PM 1 are scheduled for the first quarter of 2026.
