Fully Automatic 300~1500 Cbm Per Day Particle Board Continuous
Press Production Line
Description
The OSB manufacturing process is highly automated, using mostly
batch presses (cycle presses) of either single or multi-opening
design. With tendency for increasing productivity and efficiency,
continuous presses started to be the leader among OSB
manufacturers. In contrast to traditional batch presses, the
continuous presses show a favorable acceptance by the wood based
panel manufacturers due to their multiple advantages. Continuous
presses run with a defined pressure and temperature profile over
the whole effective length and are economical consumers of
electrical and thermal energy. They need minimal hydraulic forces
to maintain the pressure applied, or to decrease or increase it
slightly, whereas in batch presses such forces vary between zero
and maximum due to closing-opening cycles (Sandvik 2009). The
extraordinary length of a continuous press (53 to 70 m) and
pre-heating system allow it to work with a speed up to 2000 mm/sec
. A further plus for continuous presses is the pressing time
factor, which was estimated at 4.0 s/mm for the optimal panel
thickness of 16 to 19 mm. The factor depends on press temperature,
which can reach 240 oC .
The 300~1500m³/day particle board production line uses raw material
through chips preparation, flakes preparation, dring and sitfting,
glue dosing system, forming and hot pressing, cooling &trimming
and sanding section to make particle board / chipboard. The final
size can be 4 x 8, 6 x 8, 6 x 9, 4 x 12, 6 x 12, 6 x 18. The
particle board has homogeneous structure, smooth surface, good
machining specification and manufacture performance. It is the
ideal substitute of nature wood.
