GRAZ, Austria, Dec. 3, 2018 (Press Release) -International technology Group ANDRITZ has received an order from Melhoramentos Florestal to supply a high-consistency bleaching and wet lap system with a capacity of 125 admt/d to upgrade the existing thermo ground wood line at Fazenda Levantina Camanducaia, Minas Gerais, Brazil.
Start-up is scheduled for the third quarter of 2019.
The line processes eucalyptus and pine as raw material to produce unbleached and bleached market thermos ground wood pulp for local board and tissue producers. The new PHC (peroxide high consistency) bleaching stage will replace the existing spray-bleaching system in the dewatering machine and achieve highest brightness levels at lowest consumption of chemicals. A universally applicable and reliable ANDRITZ Twin Wire Press will be installed to dewater pulp to a dryness of up to 33%, followed by a high-consistency mixer to guarantee gentle blending of pulp and chemicals. In order to achieve even retention time in the bleach tower, a new ANDRITZ discharge system will ensure continuous and uniform pulp discharge.
A complete wet lap system and finishing line are also part of the scope of supply. After dewatering to a consistency of 45% on another ANDRITZ Twin Wire Press, a wetlap cutter and layboy (CLB) will operate fully automatically to form wet bale stacks. The finishing line consists of various pallet conveyors.
With this upgrade, Melhoramentos Florestal will be able to increase pulp production and, in particular, bleaching efficiency by means of a safe process with low energy consumption that will allow greater flexibility in producing various pulp grades – an important feature with which to approach a wider range of end customers.
