2 Paper Making Lines

Descripción del producto

Overview

The Plant was in production up to September ***2 and is currently configured for the manufacture of **0% recycled paper on two lines, line 1 having a top & bottom wire for the production of white top & liner papers. Speed Range ******0M/min, ******5GSM, deckle at slice ***0mm, deckle at reel ***0mm, producing ******0 Tonnes/per day continuous, line 2 being single ply only. Speed Range ******0M/min, *****0GSM, deckle at reel ***0mm, producing *****0 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
