The company decided on a complete tissue production
line supplied by ANDRITZ. The delivery consisted of a
PrimeLineCOMPACT tissue machine with steel Yankee and shoe
press as well as a complete stock preparation system, forming
fabrics, press felts and shoe press belts. It also included automation
with Metris digitization technology for remote support, which was to
provide a vital lifeline during start-up.
The tissue machine has an annual capacity of 35,000 t/y, a
design speed of 1,900 m/min and a working width of 2.80 m. The
Yankee diameter is 16 ft. The stock preparation system is split into
a short and a long fiber line and is equipped with ANDRITZ Papillon
refiners with a cylindrical refining zone. Ji Haihong, ANDRITZ
Project Manager Stock Preparation, explains: “The special geometry
of our Papillon refiners combines gentle and homogeneous fiber
treatment. Thanks to the compact rotor design, the refiner concept
offers significant improvements in energy consumption compared to
other refiners on the market.”
“ANDRITZ simply ticked all the boxes with its solution of the
complete tissue line,” says Laocharoensuk. “In addition, they have
a remarkable USP, namely their PrimeLineTIAC, the world’s most
modern tissue pilot plant. This gives us the unique opportunity to
deeply exchange know-how and to develop our products further
and to achieve even better quality. This will bring us ahead of our
competition!”
Remote assistance during start-up and for ongoing
optimization
The complete tissue production line was successfully started
up in early 2021, right in the middle of the worst of the COVID-19
pandemic. A key part of the successful start-up was down to Metris
Remote Assistance, which was utilized to the full, allowing ANDRITZ
specialists from all over Europe to fully take part in the technical
procedures. Some ANDRITZ experts were also on location during
the start-up.
“Despite the COVID-19 situation we had full support from
ANDRITZ,” says Laocharoensuk. “We had technicians on site,
as well as remote assistance and I have to say that our mill team
here together with ANDRITZ did a great job and we achieved a
remarkable result. We even started up on time.” Tine Kocbek,
ANDRITZ Project Manager Tissue, says, “Managing the start-up
with remote assistance by experts from our European locations
and colleagues on-site at Prachinburi was quite an experience,

especially in the middle of a serious pandemic. This project to
me was like my very own baby, and I must admit I had one or
two sleepless nights. However due the open communication and
absolute respect from both sides, we mastered the challenge.”
Remote assistance via Metris has continued as PM 5 now
is up and running and adding another 20 t/d of high-quality tissue
production to the mill’s total output of 90 t/d. Pisit Samatta, Associate
Manufacturing Director, BJC Cellox, says, “One of the features
we are really pleased with on the new tissue line is the remote
assistance we receive from ANDRITZ when optimizing the efficiency
of the machine. Specialists are able to see exactly how well the line
is running, and offer assistance to optimize the line even further.
“This was really helpful during the learning curve when we started
up, and now to have remote assistance whenever we need it has
come in really handy.”
“Due to the open communication
and absolute respect from both
sides, we mastered the challenge.”
