Phenolic aldehyde China made oriented strandboard production line
OSB line based on wood as raw materials, shavings, glue, auxiliary equipment, hot pressed density 550-750kg / M 3 man-made sheet. It has a fine smooth surface structure of the core layer gradient, and has good heat insulation, sound insulation and good machining properties, is widely used in manufacturing furniture, high-end cabinets, speakers, and other interior construction and transport. We produce an annual output of 30000-60000 cubic meters of particle board equipment, in a dry, auxiliary equipment, hot press has done a great section in the technical modifications, reduce investment, improve the quality of the products.
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.
3) 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.
4) 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.
5) Sanding section:
The board are sanded,checked and stored.
PLC control is used in mat-forming section.
