dryer section of the PM5 at its

The PM5 line, which produces
cardboard and solid board in the
basis weight range from 220 to
540 gsm, will have its production
capacity and efficiency improved
when the project is completed in
the third quarter of 2023.

commissioning, and start-up
assistance.
Øistein Vedahl, managing
director of Ranheim Paper
& Board, said: “This rebuild
represents a strategic investment
aimed to increase the production
and efficiency of PM5. We
selected Toscotec because we
knew their ability to successfully
manage rebuild projects, and
we were impressed with their
technical solution during the
discussion of the project.”

1884, the mill was renamed
Ranheim Paper & Board after the
restructuring in 2016 of Peterson
Packaging group. With capacity
for 120,000 tons per year of
paper and 50 million square
metres of solid board, it is owned
now by Fundermax.
Twin wire press retrofit at
Winstone Pulp International
Winstone Pulp International is
having a comprehensive twin
wire press retrofit carried out by
Andritz at its Karioi pulp mill in
New Zealand.
The current Andritz twin wire
press with a working width of 2m
has been in operation since the
mill opened in 1978. To improve

reliability and safety, Andritz will
replace the machine’s carbon
steel frame with a stainless-steel
version and modernise other
machine components. The order
was said to have been won on its
ease of replacement.
The retrofit will leave the
machine foundations and
connections basically untouched.
All installed rolls and bearings

for easier and safer wire
replacement
l a modernised headbox with
modified outlet geometry
for improved pulp sheet
formation
