8-25MM Laminates MDF production line
The MDF production line consists of chip preparation, fiber preparation, glue mixing and applying,
mat-forming and hot-pressing, cooling and sizing, sanding. It can be used in furniture-making,  flooring-making, packing industry, sound box, construction and decoration of vehicle or vessel etc.
We can provide 1500-8000 m3 MDF production line as well as a single machine supplement such
as chipper, refiner, dryer, forming machine, pre-press, hot press etc.
This productiong line consists of five technology process flows:
Â
1) Chip preparation section  Â
Wood, branches and wood residues are cut into chips of definite size. Chips from chips silo will beÂ
screened to remove fines,soil and stones.
2) Fiber preparation section Â
Chips are transported to upper bin of refiner, and positively fed toÂ
digester by screw feeder for steaming. Steam chips will be distintegrated to fiber under the forceÂ
of heat and mechanism. Mix dryingmedium and wet fiber which is in the state of suspension withÂ
the help of high pressure airflow,and thus exhaust moisure in fiber via drying medium to ger dry fiber.  Dry fiberfalls on belt conveyor through cylone discharge valve, and then be transported to dry fiberÂ
bin for storage.          Â
3) Glue mixing and applying section        Â
 Process of glue applying before drying is adotpted.Feed molten paraffin and water-proof additive to fefiner. Paraffin is mixed with fiber uniformly under the force of refiner plates.Â
Glue is transported to the below line of fiber discharge valve. With the help of 2830m/s highÂ
speed air flow,glue mist meets and attachs to the surface of fiber. This section can beÂ
controlled by PLC or computer.
Â
4) Mat-forming and hot-pressing section
The fiber after drying is transported to the above of forming machine, and uniformly spread ontheÂ
conveying mesh belt in the way of air-flow.Vacuum box equipped below the mesh beltÂ
provides negative pressure and air will be removed via mesh belt,fiber stays on mesh belt andÂ
thereafter forms mats gradually. Fluffy mats will be pressed by pre-press. Pressed mats are cut into definite length by longitudinal and transversal saw, thenÂ
transproted to loader passingÂ
through accelerating conveyor, stoage conveyor and extension conveyor. When finishing loadingÂ
mats,carriage in the loader will feed conveying belt and mats into hot press,at the same time,Â
shovel head at the front end of conveying belt pushes out pressed board.When carriage coms toÂ
terminal,boards have been into unloader,and mats also arrives to due position.Carriage returns,
conveying belt turns forward. Mats are in relative still state and stay on the platen of press whenÂ
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 andÂ
thickness form. Rough boards will be put on support via loader. Outfeeding conveyor will unloadÂ
boards one after another to next section when cage comes down.
5) Cooling, sizing and sanding section
Rough boards after air cooling are turned in to cut-to size boards via longitudinal and transversal saw. And then cut-to-size boards are sanded, sorted, stacked and packed for sorage.
