Wood, branches and wood residues are cut into chips of definite size. Chips from chips silo will be screened or airgraded to remove fines, soil and stones.
2.Fiber prepare section
Chips are transported to upper bin of refiner, and positively fed to digester by screw feeder for steaming. Steamed chips will be disintegrated to fiber under the force of heat and mechanism. Mix drying medium and wet fiber which is in the state of suspension with the help of high pressure air flow, and thus exhaust moisture in fiber via drying medium to get dry fiber. Dry fiber falls on belt conveyor through cyclone discharge valve, and then be transported to dry fiber bin for storage.
Glue making system
All the glue making section is full automatic , can make urea-formaldehyde glue ,E1 glue ,E2 glue and ect..
Glue dosing system
Process of glue applying before drying is adopted. Feed molten paraffin and water-proof additive to refiner. Paraffin is mixed with fiber uniformly under the force of refiner plates. Glue is transported to the blow line of fiber discharge valve. This section can be controlled by PLC or computer
3.Fiber drying section
The fibers after mixing with glue is transported to drying ducts along with steam, and transported to cylcone separator by hot air. And thus the water in the fibers is drained out with hot air. The dried fibers and air is separated and then transported to silo.
4. Mats forming section
The fiber after drying is transported to the above of forming machine, and uniformly spread on the conveying mesh belt in the way of air-flow. Vacuum box equipped below the mesh belt provides negative pressure and air will be removed via mesh belt, fiber stays on mesh belt and thereafter forms mats gradually.
Pre-press section
Fluffy mats will be pressed by pre-press. Pressed mats are cut into definite length by longitudinal and transversal saw, then transported to loader passing through accelerating conveyor, storage conveyor and extension conveyor.
Hot press section
when velocity of conveying belt is the same as the returning speed of carriage. Glue in the mats cures, thanks to temperature and pressure in hot press, and hence boards with definite intensity and thickness form. Rough boards will be put on support via unloader. Outfeeding conveyor will unload boards one after another to next section when cage comes down.
Cutting section
4x8ft/6x9ft/6*12ft size we can design on your requirement.
