OSB(Oriented strand board)production line, working flow: wood debarker→flaker→chip silo storage→chip drying→screen→glue dosing and spreader→forming→prepress→hot press→cooling→cutting→storage
1. Chip preparation section Raw material is reduced into qualified chips by the OSB chipper, after the chipper machine ,we can got 40-100mm length ,5-20mm width,0.3-0.7mm thickness chips. 2. Sifting section After got the chips , through the belt conveyor ,the chips go into the rong screen section ,after the screen we can separate the good quality chips and disqualification chips ,the satisfying chips go into the next processing, and disqualification chips back to chipper again working. 3. Drying section The flakes discharged from the wet flake bin are conveyed to the 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. Glue dosing and spreader section The chips after drying section got the ideal moisture , then mix with the glue together depends on our design ratio. 5. Forming section The surface and core flakes are sent into chips forming machine, and forming on the mat conveyor length way and width way cross forming uniformly by the orientation plate. 6. Forming section The surface and core flakes are sent into chips forming machine, and forming on the mat conveyor length way and width way cross forming uniformly by the orientation plate. 7.Hot press section: After hot press ,the mats OSB get into the hot press machine , after high pressure and high temperature working ,then we got ideal quality OSB 8. Cooling section After hot press, the rough board is conveyed to star-cooler for cooling , cooling machine normally we have circle type and round type ,design depends on customer workshop size. 9. PLC control section The PLC electronic control system can realize the centralized control of the entire production line and the integrated control of the production process. 10.Heating energy center Supply heating for the process of drying ,hot press, glue making section .Caloric value can customized design from 12-60MW.
