Product Description
MDF is a kind of excellent substitute for natural wood panel with wide application. Materials such as wood and other plant fiber after being added suitable urea formaldehyde resin or other adhesives forms 450-880 kg/m3 panels on hot press. The panels are characterized with tight and smooth surface, uniform core layer and good wood working performance.

The line consists of chip preparation, fiber preparation, glue mixing and applying, mat-forming and hot-pressing, cooling and sizing, sanding.

1. Chip preparation

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 preparation 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.

3. Glue mixing and applying section

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.

4. 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.

5. Mat-forming and hot-pressing 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. 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. When finishing loading mats, carriage in the loader will feed conveying belt and mats into hot press, at the same time, shovel head at the front end of conveying belt pushes out pressed board. When carriage comes to terminal, boards have been into unloader, and mats also arrives to due position.

Carriage returns, conveying belt turns forward. Mats are in the relative still state and stay on the platen of press 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.

6. Cooling, sizing and sanding 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.
