Pressurized refiner can be used for MDF/HDF production line with
capacity range from 30,000 to 200,000cbm per year
5~30 Tons Per Hour Fiber Making Refiner for MDF/HDF Production Line
Description
A preferred material for furniture, flooring or ceiling panelling:
medium-density fibreboards (MDF) are in use around the world. Their
quality depends on proper production. Büttner supplies the
wood-based panels industry with energy systems, drying systems and
burners, which ensure that wood fibres are quickly and efficiently
dried, before they are pressed.
Medium-density fibreboards are made of wood fibres and
characterised by their especially homogeneous structure. This
allows for the edges to be machined directly as well as a direct
painting process. MDF is utilised both in furniture construction
and in the production of laminate flooring or ceiling panelling.
Medium-density fibreboards are normally produced from fine wood
fibres and glue. Depending on the region and availability, pine,
spruce, beech, poplar, as well as eucalyptus and rubberwood trees
are used. After the wood has been reduced to fibres, it is mixed
with glue in a refiner and then dried in flash tube dryers. The
required thermal energy is normally generated by energy systems,
which burn both the waste material from the production process as
well as purchased fuels such as biomass, oil or gas. The drying
system can be heated directly with flue gas, turbine exhaust and
burners, as well as indirectly with steam.
BM pressurized refiner adopts the patents and combined
international advanced technology. The technical data and
performance are close to the advanced level of world-famous similar
products. The refiner has advanced structure, high automatic and
easy operation, reliable and precision running, which can produce
high quality fiber with lower moisture.
Pressurized refiner can be used for MDF/HDF production line with
capacity range from 30,000 to 200,000cbm per year.

Key parts of refiner
With large compression ratio, wood chips are de-watered during
conveying with the new feeding plug screw, which reduce the drying
energy, meanwhile, the wood chips are crushed, which is good for
grinding. Structure distinguishing feature: overlay and coat one
layer of wear-resistance material, improve the plug screw service
life. Inside the cone pipe, reinforced bar are inlayed, which can
reduce maintenance cost. Speed-adjustable DC motor can provide
large torque and good performance.
Large diameter stainless steel vertical digester vessel has lower
height which has lower requirements for the civil construction. In
desigh of MDF pressurized refiner whose capacity is more than
100,000.0 cbm per year, double screw feed system are used, which
can supply the raw material continuously to improve the fiber
quality.
