52 Inch High-Performance Refiner for MDF/HDF Production Line
5~30 Tons Per Hour Fiber Making Refiner for MDF/HDF Production Line
Description
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.
The pressurized refiner has following main innovation and key
technology:
(1) Main shaft adopts the patents from national institutes;
(2) For vary productive capacity, the thrust bearing employs top
brands;
(3) Use domestic mechanical seal and its cooling system;
(4) Use extrusion plug screw with high-efficiency de-water
structure;
(5) Grinding plate employs optimized teeth shape;
(6) Compact machine structure, high running precision, easy to
maintain;
(7) Reliable hydraulic and electric control inter-lock system;
(8) Heat expansion auto-compensation system is equipped with.

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.
- Water cooling system
- Lubrication system
- Hydraulic system
- Electrical control system
A fantanstic way to make wood chips to wood fiber.
