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.

Assembly of refiner system

Main technical data

Key parts of refiner

• Feeding screw

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.

• Feeding screw

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.

• Main shaft assembly

• Water cooling system
• Lubrication system
• Hydraulic system
• Electrical control system

A fantanstic way to make wood chips to wood fiber.
