| The medium density fiberboard is processed(through sections of material preparation, fiber preparation, regulating and supplying glue, forming and hot pressing, post-processing, and sanding) to be 450-880kg/cm³ from the raw material of wood fiber or other plant fiber. And the raw material can be woods, brush woods, and the processing residues of woods. |
| Raw Material |
Wood branch, Waste wood, Log, etc |
|
Capacity |
30,000~300,000cbm/year |
| Board size |
4×8ft, 6×9ft, 6×8ft, 6×12ft, etc |
|
Working days |
300days, 22hours/ day |
|
| 1) Material preparation section |
| After the raw materials are sawed to wood pieces in certain sizes by wood chipper and stored in material warehouse, clean up to the impurities, such as fines, earth and sands, in the wood pieces through screening. |
 |
|
 |
| 2) Fiber preparation section |
| Feeding the wood pieces into the boiling apparatus evenly to cook and soften through sequeezing and dewatering after transfering them into the defiberator pre-heating bins/humidifying bins by the transfering equipment in order to separate the fibers easily. The cooked wood pieces will be seperated to fibers under the forces of heat and machine. Then mix the wet fibers and heated dry medias, and keep the fibers suspending in the drying medias under the high speed force of the high-pressure air flow, and the moisture in the fibers will be taken away by the dry media. Afterwards, the fiber will drop the force of cyclone separator onto the reversible belt conveyor to be transferred to the pavement bins for temporary storing. |

| 3) Forming and hot pressing section |
| The dried fibers are transferred into the paver metering bin by the pneumatic system, and the paving rolls of the mechanic vacuum paver paves the fibers onto the circular conveyor. And the air will be sucked away by the mesh belts, under which there is vacuum case forming negative pressure, as while, the fibers are sucked on the mesh belt and form slabs gradually. In the next moment, the fluffy slabs will be compacted by the pre-press machine, and be sawed vertically and longitudinally to lengths required, and then the slabs will be transferred to the loader by the synchronous conveyor, speed-up conveyor, storing-board conveyor and extensible conveyor succecssively. After being loaded by the loader, the small machine in the loader will transfer the slabs together with the cantilever belt into the hot press machine. During the tranferring process, the shovel at the front of the conveyor belt push the compacted slabs out, and the rough boards will enter the unloader as well as slabs get to the preset position when the small machine arrives at the termination. Then the small machine draws back as the belt revolve forward. The revolving speed of the belt is equal to the back speed of the small machine, so that the slabs are relatively static and stay on the hot press. The slabs will be formed to specified thickness under the temperature and pressure of the thermal compressor, and the inside glues will solidify. At last boards of certain strength will be made. Then the boards will be unloaded onto the carrier by the unloader, and unloaded and transferred to the next process by the discharge machine gradually when the suspension coop goes down layer by layer. |

 |
| 4) Finishing and sanding section |
The thermal-compressed slabs will be cooled through turning over and transferred to the vertical and horizontal sawing machine by the roller conveyor to be sawed into medium density fiberboard in required sizes, and at last, to be separated, stacked, packed and transferred to the warehouse after sanding.
