Overview
The Plant was in production up to September 2012 and is currently
configured for the manufacture of 100% recycled paper on two lines,
line 1 having a top & bottom wire for the production of white
top & liner papers. Speed Range 520-350M/min, 180-125GSM,
deckle at slice 3200mm, deckle at reel 2850mm, producing 170-200
Tonnes/per day continuous, line 2 being single ply only. Speed
Range 280-400M/min, 80-200GSM, deckle at reel 2200mm, producing
80-100 Tonnes/per day continuous.
Both paper machines have Valmet Dematic XDI systems which run motor
stop/start functions including flows, pressure, temperature and
level controls within the mill. The paper machines and stock
preparation are well supported with documentation and spares. The
plant has been maintained on a regular basis
