45 Inch High-Performance Refiner for MDF/HDF Production Line

5~30 Tons Per Hour Fiber Making Refiner for MDF/HDF Production Line

Description
The production of woodchips
Everything starts with the wood. The panels can be produced by many wood and non-wood species, but they have a common demand: good chip quality will be the starting point for a nice MDF panel.
In making a good woodchip, the chipper is the key-player. A good chipping will result in above 90% accepts, few pin chips and overs. Rejects must be treated properly. Oversizes are re-processed and back to the main stream, and fines are sent the energy plant.
Bad chipping will cause uneven chip distribution, a lot of fines, oversize, overthick and poor refining and low fiber quality.

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
