1220*2440mm OSB Production Line/chip board plant

1. Chip preparation section

 Raw material is reduced into qualified chips by the drum chipper,  then the chips are transported to the chip bin, and then feed to the  knifering flaker by which the chips are turned to flakes, then the  flake stored in wet flake bin.

2. Drying and sifting section 

The flakes are discharged from the wet flake bin which are conveyed to the rotary dryer.

Qualified core flakes are stored in core flake bin; oversize flakes are send to mill to be re-

crushing, and transported to surface dry wood shavings bin to be stored. 

3.sizing section 

 After scaled, the core and surface flakes are to be effectively  and uniformly mixed with qualified glue to achieve the uniform mixing and the sufficient sizing effect.

4.Paving and thermoforming section  

The after sizing shavings are transported to the mechanical grading paving machines by

the belt conveyor.and they are paved to the uniform flat slab. After a series of processes

such as pre-press, lengthwise saw, cross saw, accelerate conveyor, storing conveyor and

loading conveyor,the rough boards are sent to the installed hoistingcages,then the rough

boards are pressed by the hot press machine.

5. Post--processing section

The thermofoming boards are conveyed to the panel turnover machien to become cool,then

the boads are transported to the vertical and horizontal edge cutting machine by the

cooling conveyor. 

6.sanding section

 The boards are sanded, checked and stored .
  PLC control is used in mat-forming section.
