World debut for technology in
Dongguan Jianhui’s new pulping line

ongguan Jianhui
Paper in China has
successfully started
up a new mechanical
pulping line supplied by Andritz
including the world’s first
TwinFlo Prime refiner.
The newly-developed
TwinFlo Prime optimises the
pulp flow to each refining
zone by means of improved
refining gap adjustment. This
is said to reduce wear on the
refiner plates and results in
longer plate life and lower
maintenance cost.
“We are very proud to be the
first ones on the market with
such innovative technology,”
said Li Guihua, president of
Dongguan Jianhui Paper. “With
the TwinFlo Prime and the new
mechanical pulping line from
Andritz we have reached a very
high level of flexibility both in

the use of raw materials and
the fibre quality produced. This
will help us further expand our
board business. The installation
perfectly meets our strategic
targets.”
The pulping line, which has
been installed at Dongguan
Jianhui’s mill in Dongguan City,
Guangdong Province, is based
on Andritz’s patented P-RC
APMP process. At a design
capacity of 600 tons per day,
it processes eucalyptus wood
chips for production of a range
of top-quality board grades.
The focus of the system is on
chip impregnation and refining
(HC and LC) with the highest
production efficiency and welldeveloped fibres at low energy
consumption.
Dongguan Jianhui Paper,
founded in 2002, runs four paper
making lines and specialises
in the manufacturing of highquality white coated duplex
board with gray back and test
liner.

up by Voith training
Following its entry to the tissue
industry in 2021, MG TEC
Industry in Romania has started
up a second Andritz tissue line
at its Dej mill.
Dorin Mocan, chief executive

The start-up in November
2022 of the world’s largest
kraftliner machine, SCA’s
PM2 at the Obbola mill in
Sweden was facilitated in part
with commissioning training
provided by Voith’s Papermaking
Academy, and comprehensive
documentation.
“A key factor to the successful
start-up here in Obbola has
been the training given to the
employees,” says Lisa Lundström
Hämälä, Process Engineer at
SCA. “Voith prepared extensive

preparation system, pumps,
automation, hall ventilation, and
electrical systems.
The stock preparation system
includes an approach flow system
and broke handling. TwinFlo
disc refiners lead to optimum
development of fibre properties,
and the ShortFlow concept
enables fast grade changes and
high flexibility. The 2.85m-wide
tissue machine has a design
speed of 1,900 metres per
minute.

SCA together made sure there
were several occasions for each
training so employees could
attend while also running our
old, now closed paper machine.”
With the Papermaking
Academy, Voith offers target
group-specific training
programmes and courses that
cover the entire life cycle of a
paper machine and the plant’s
components.
