Papelera del Sur S.A., part of Cartones America Group, Peru, successfully started up its rebuilt PM 5 on March 28 at Chincha, Peru, after a drying section upgrade carried out by Toscotec, Italy. PM 5 produces white top test liner, brown test liner, corrugating medium, and fluting starting from recycled paper.
Cartones America is a privately-owned, Andean Region manufacturer of containerboard, corrugated boxes, clay-coated paperboard, spiral tube board, and specialty board packaging products. The company was born in Cali, Colombia, in the 1950s, but today also has operations in Venezuela, Ecuador, Peru, Chile, and Argentina.
The project objective was to increase production and optimize efficiency of the paper machine. This has been achieved by adding new dryers at the end of the existing drying section, eliminating the rope tail threading system from the last two batteries and installing a new air blow threading system, the company reports.
Toscotec's scope of supply consisted of a complete new double-tier drying battery with 6 TT SD (Toscotec's steel dryer cylinders) 2,000 mm dia, 10 bar coded. The installation of TT SD 2,000 mm dia allows the mill to get a large drying surface with a smaller number of dryers and related accessories (such as wire rolls, doctors, in-drive points, etc.) compared with the installation of standard 1,500 mm dia dryers. This results in a lower investment cost but also in energy saving.
