Product Description

What is OSB?
Oriented strand board (OSB), also known as flakeboard, is a type of engineered lumber similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. OSB may have a rough and variegated surface with the individual strips of around 2.5 cm × 15 cm (1.0 by 5.9 inches), lying unevenly across each other and comes in a variety of types and thicknesses.

What is OSB production line?
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 prepare 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. Pre-press section:
After the flakes forming on the mat conveyor uniformly, through the metal remover , to the pre-press machine, to make the first form section.

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. Cutting section

After hot press machine , the boards to the cutting machine , 4x8ft,6x9ft,6x12ft all can design depends on customer requirement.

9. Cooling section

Rough boards after air cooling are turned into cut-to-size boards via longitudinal and transversal saw. And then cut-to-size boards are sanded, sorted, stacked and packed for storage.

10.Heating energy center
Supply heating for the process of drying ,hot press, glue making section .Caloric value can customized design from 12-60MW.
