Particle board is made from small-diameter wood, branches, wood residues and non-wood agricultural residues via Chip preparation, drying, spreading and hot press section. Finished boards can be used for furniture, building, packing, vehicle and decoration and lamination.
1. Chip preparation section
Raw material is processed into qualified chips by the drum chipper, then the chips are transported to the chip silo, and then feed to the knife-ring flaker by which the chips are turned to flakes, finally the flake stored in wet flake silo.
2. Drying and sifting section
The flakes discharged from the wet flake silo are conveyed to the rotary dryer or three-way dryer machine. After drying process, qualified core flakes are stored in core dried particles silo; oversize flakes are send to mill to be re-grinding, and transported to surface particles silo.
3. Glue regulating and blending section
After scaled, the core and surface flakes are to be effectively and uniformly mixed with qualified glue independently via face layer glue blender machine and core layer glue blender machine.
4. Forming and hot-pressing section
The surface and core flakes are sent into diamond-forming machine, and forming on the mat conveyor uniformly. After processes of metal remover, pre-press, lengthwise saw, cross saw, accelerate conveyor, scaling conveyor, storing conveyor and loading conveyor, mats are transported to carrier and then to hot press. Rough boards after pressing are pushed to unloader.
5. Cooling and sizing section
The rough board is conveyed to star-cooler for cooling, then the rough board goes through side trimming saw and become a qualified particle-board, stacked on the hydraulic lift.
6. Sanding Section
The board are sanded, checked and stored .
