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
sheep decoration and lamination.
1) Chip preparation section
Raw material is reduced into qualified chips by the drum
chipper, then the chips are transported to the chip bin, and then
feed to the knife-ring flaker by which the chips are turned to
flakes,then the flake stored in wet flake bin.
2) Drying and sifting section
The flskes discharged from the wet flake bin are conveyed to
the rotary dryer. Qualified core flakes are stored in core flake
bin; oversize flakes are send to mill to be re-crushing, and
transported to surface flake bin.
4) Forming and hot-pressing section
The surface and core flakes are sent into classi-forming
machine, and forming on the mat conveyor uniformly. After process
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 pressing.
Rough boards after pressing are pushed to unloader via pallet.
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.
PLC control is used in mat-forming section.
