The 110~500 cbm/day PB production line has automatic operation system, reasonable technical process, stable running. It can produce 4 x 8, 6 x 8, 6 x 9,6 x12 sized PB. This production line uses the waste of wood process factory and branches of wood as raw material, after chipping, flaking, drying, sifting, hot-press, sanding and cutting to produce particle board. The particle board can be used for furniture, building construction, package, inner decoration of vehicle and ship, and short-cycle over-laying particle board for decoration.
- Chips and Flakers Preparation Section: Raw material is reduced into qualified chips, after screening the chips are transported to the chip bin, and then feed to the knife-ring flaker in which the chips are turned to coarse flakes, then the flake store in wet flake bin.
- Drying and Sifting Section: The wet flakes are conveyed to the dryer, after sifting the qualified dry flakes are transported to core flake bin for temporary storing; oversize flakes are sent to double-stream mill for re-crushing, after re-crushing, the fine flakes are sent to surface flake bin for temporary storing
- Glue Dosing System: After metering, the qualified core and surface dry flakes are conveyed separately to the glue blender, meanwhile the qualified glue as per the requirement of technical process, is sent into the glue blender also. Then the flake and glue are mixed by the stirring of glue blender, with even glue dosing.
- Forming and Hot-Pressing Section: The surface and core flakes are sent into mechanical classic-forming machine, and spreading on the mat conveyor, a continuous mat which features in top and bottom layer with fine flakes, coarse flakes in the core layer, gradually changed structure. After passing ferro remover, pre-press, longitudinal saw, cross saw, acceleration conveyer, scale conveyer and storing conveyer, infeed conveyer, the mat is sent to the cage of loader, then the mats are fed to the hot press to press into rough board, finally, the pressed board is discharged into the un-loader.
- Cooling and Sawing Section: The rough board in the un-loader is conveyed to star-cooler for cooling. Then the rough board goes through side trimming saw by longitudinal and transversal saws and become a sized particle-board, finally transported by roller conveyer and stacked on the hydraulic lift platform.
- Sanding Section: The rough board after cooling and curing, is sanded by wide-belt sander to required thickness and roughness. After checking, the board is sent into a ware-house.

- Good adaptation of raw material: Small wood-log, branches, residue of the wood processing, can be used as raw material for particle board.
- Lower glue consumption: The electrical measuring and adjusting of the ratio between various materials and glue, the proportion between the flakes and the glue can be controlled by computer system on line. High pressure glue injection, can ensure the glue mist very well, which is good for glue blending and lower the glue applying consumption.
- Homogeneous structure of mat: The forming machine adopts the advanced mechanical classic-forming, with special diamond roller, to ensure ideal spreading, improve the board quality in the end.
- Hot-pressing system: Adopting multi-opening press, ensure the press closing synchronal by both mechanical and hydraulic methods. The board thickness tolerance is less, in order to reduce sanding amount.
- High efficiency automatic control: The whole electrical control system of the production line adopts world advanced electrical elements, the control system work reliably and stably.
