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. |
