Paper Machine Woven Type and Spiral Type Dryer ScreenCompany
ProfileHuatao Group is set up in 2008. The main business is to
serve the pulp and paper industry by providing quality accessories
and paper machine enovation services to help customers solve
various problems in production, improve production efficiency and
reduce energy consumption.Huatao Group has a professional
technician team that devoted to pulp and paper industry. We
are able to make the best proposal after completely analyzing and
figuring our problems of the paper production line though
paper-making progress, equipment, electric automatization and so
forth.Product DescriptionWoven Type Dryer Screen / Dryer Fabric /
Dryer CanvasIn the dryer section of paper machine, the
paper sheet travels around large-diameter heated cylinders, where
the balance of the water is removed by evaporation. Dryer
screen hold the sheet tightly in contact with the cylinders
through the dryer section. Constructed of monofilaments, dryer
fabrics must be heat resistant, rugged, and designed for both
drying efficiency and runnability. Huatao leads the
industry in China in the design and application of dryer products,
including the pin seam, active air handling, and heat-resistant
fabrics.Dryer fabrics are fully resistant to hydrolysis and able to
withstand all heat and humidity conditions in the dryer section.
Most of the standard types of fabrics can also be made
of polyester yarns. Polyester dryer screen are
suitable for drying positions where the whole dryer screen is
hydrolyzed. Polyester can considerably extend the service life
of the fabric and help avoid the risk of its failure during the
operation of the paper machine because of decreased fabric
strength.Spiral Type Dryer Screen / Dryer Fabric / Dryer
CanvasThe spiral dryer fabric is a specially engineered paper
machine clothing for the drying sector in the paper mill, also
widely deployed in many other industries like food drying, nonwoven
conveying, printed textile drying, etc. The spiral-linked dryer
fabrics featured for its continuous seamless screen, excellent
strength and abrasion & distortion resistance, and greater and
adjustable ventilation.The unique seamless spiral-linked screen
surface is ideal for the drying sector of mark-sensitive papers,
and the application where a seam is unacceptable. Each spiral loop
could be a joint, the seam is identical to the fabric body itself.
It's easy to install and repair to reduce downtime and increase
long-life of the seam to save cost, as it is well known the joint
is always the weakness of a circuit belt.Huatao's spiral
fabric belt for the paper dryer is made out by high-viscosity PET
yarn with hydrolysis-resistant masterbatch additive, to achieve
much better durable properties and long service life. Normal
Polyester yarn is easy corrosive and degraded by the heat steam,
then become brittle and the integral dryer belt fabric have to be
replaced. The additive of hydrolysis resistance masterbatch
lengthens the service life 2-4 times more than the normal Polyester
under thermal (100c-170c) drying working condition.Comparing to the
woven dryer fabric, the spiral dryer mesh belt has greater air
permeability and drying efficiency. Permeability is the crucial
parameter of a dryer fabric. Spiral dryer fabrics have greater air
permeability than other dryer fabrics under the same working
condition, it could help to lower the steam pressure in drying
cylinder, or fast speed under the same pressure. All these help
enhance drying efficiency and save at least 10% of the energy cost,
which is more economical.Huatao provides a broad range of
spiral dryer screen for every drying sector.According to the
yarn diameter and spiral ring size, we have small, medium and large
loop. The large loop use thicker yarn to get superior tensile
strength and ventilation, although coarse surface. And small loop
has thinner yarn, lesser air permeability and fine surface.The air
permeability is adjustable by insert round or flat yarns into the
spiral ring, to adapt different application and drying sector.Flat
yarn spiral dryer screen are also available, its greater sheet
contact area and lower permeability and caliper than the standard
spiral, suit for where woven products may not perform as
desired. At present, this type dryer screen permeability can
be less than 100CFMHuatao provides a broad range of spiral
