Roundwood logs are brought in by lorry from surrounding
forests e.g. Kielder Forest, unloaded and stacked ready for the chipping
process
|

Egger bring in recycled wood from a sister company in Leeds
and also from local wood recycling companies (associated with Newcastle,
Gateshead and Durham Councils).

One of the
most useful raw materials for making chipboard is sawdust from local
sawmills.
|
 |

|
The roundwood
logs are fed into a machine to remove bark and any grit/sand stuck
to it.
|
 |
5
|
Logs are fed
into the flaker machine and are shaved or cut to make wood flakes,
chips and shavings.
|
 |

|
The recycled
wood is fed into a machine known as a Grizzly Mill, which smashes
the wood into woodchips with revolving metal hammers and discards
all other waste products.
|
 |
7
|
Woodchips are
passed up a conveyor and the metal, plastics and rags removed from
the woodchips.
|
 |
8
|
The crushed
wood is deposited in storage bays ready to be used for further processing
into chipboard.
|
 |

|
One of the
waste products is scrap metal which is pulled from the crushed wood
by a powerful magnet and spat out into a skip and the metal is sold
and recycled.
|
 |

|
Woodchips from
the recycled timber and logs are dried in a big drum by hot air produced
from burning the very fine waste wood dust.
|
 |

|
Birds eye view
into the burning chamber which creates the heat to dry the wood chips.
|

|
At a cost of
£3 million, Egger has built a WESP (Wet Electrostatic Precipitator)
which removes the pollutants and dust from the wood drying process

The wood chips
are now mixed with glue and wax. The glue is used to bond the chips
together and the wax makes the chipboard water resistant.
|
 |
14
|
The woodchips
are now ready for pressing and are fed into a forming station and
then onto a conveyor belt called a forming line.
|
 |
15
|
One of the
production lines at Hexham is 52 metres the longest of its kind in
the world.
|
 |
16
|
From the forming
line the chipboard moves to a pressing plant where the moisture is
driven off and board is pressed at high temperature and pressure in
the main press.
|
 |
17
|
The edges of
the board are trimmed and the board cut into panels typically 5610mm
x 2070mm before being cooled, sanded and packed for storage in the
warehouse.
