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.

Summary of process flow

1. Chips Preparation Section: The raw material is reduced into sized wood-chip, then the wood-chip is conveyed into a chip silo for temporary storing, via swinging screen to remove small particles, mud and sand.
2. Fiber Preparation Section: Wood-chip out-feeding from pre-heat silo, entering digester vessel via plug-screw feeder to cook and soften the wood-chips, the cooked wood chip is reduced into fiber by the function of heat and mechanical movement. Then the wet fiber is conveyed by high-speed & high-pressure wind via cyclone &rotary discharge fall to the forward-backward belt conveyor, then sent to forming metering silo.
3. Glue Dosing System: Our technique is glue dosing before drying. Melt paraffin is sent to the de-fiberator, mixed homogeneous with the fiber. The glue mist adheres to the surface of fiber by the high-speed wind-flow in the drying pipe.
4. Forming and Hot-Pressing Section: Dry fiber is sent into the metering silo by wind-conveying system. There is vacuum box under the mesh belt. Fiber is adhered on the mesh belt, thus forming a mat. Pressed by the pre-press, the mat becomes into a relatively density mat, then cut into sized mat by mat-transversal-longitudinal saw. Transported by synchronous-belt-conveyor, acceleration-belt-conveyor, storing-belt-conveyor, etc. The mat is carried to board loader. The caul-less belt-tray of the loader transports the mats into hot press, meanwhile, the pressed rough board is pushed out on the un-loader. The mat stays on the press-platen of a hot press, then it is pressed into a certain thickness under the function of high-pressure and high temperature. The un-loader discharges the board one by one.
5. Cooling &Trimming, Sanding section: The board after hot pressing, passing a board-turning-cooling machine, roller-conveyor, then entering transversal-longitudinal saw, is cut into size medium density fiberboard. After sanding, checking, rating, stacking, packing, finally the board is sent into ware-house for storage.

 

Main characterisitcs

 

1. Adopts reliable, steady running de-fiberator made under latest-tech, which can control the fiber quality and meet the productive capacity requirement, greatly reduce the consumption of electricity and heat.
2. The pre-press adopts mesh belt, upper and lower belt are driven separately, to avoid the influence on the mat quality caused by speed-difference of the two belts and wind discharge problem.
3. Mat conveying line is composed by flexible belt conveyer and saw acceleration belt conveyer, lest the mat distort during accelerating and departing.
4. Hot pressing adopts the technical-process-curve of all position control, to ensure the board section-structure-density and stable quality.
5. The wide-belt-sander improves the board finish quality, lowers the running cost.
6. The electric control system adopts the world-advanced PLC control system, with on-site communication BUS control, the customer can set the technical-process-data, operate and monitor the machine on line, record the mal-function during the production. The computer -control is more reliable, and the line can work stably.

Key equipment

1.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.


2.Digester

Large diameter stainless steel vertical digester vessel has lower height which has lower requirements for the civil construction. In desigh of MDF pressurized refiner over 80 thousand annual capacity, double screw feed system are used, which can supply the raw material continuously to improve the fiber quality.
