GRAZ, Austria, July 28, 2014 (Press Release) -Following successful modernization of the pulp drying line by international technology Group ANDRITZ, Altri Celbi increased its production capacity from an average of 2,000 tons per day (air dry metric tons) to a peak value of 2,150 tons per day at the Leirosa mill, Portugal, on July 7, 2014.

In terms of specific drying capacity, Celbi was thus able to break its own world record of 421 tons per day and meter of working width, established in May 2013 also with ANDRITZ technology, by achieving 440 tons per day and meter of working width on the 4.88 meter wide sheet drying plant.

Based on these peak values to be achieved over periods of several days, Celbi will achieve average daily production of around 2,100 tons and a specific drying capacity of approximately 425 tons per day and meter of working width.

After extensive upgrade work by ANDRITZ (including an upgrade of the pressure screening plant and the Twin Wire Former, and modification to the bale finishing area), the Celbi plant was started up again in February 2014 following a scheduled annual shutdown. In a next upgrade stage (installation of a new, second shoe press, dryer upgrade) during the first half of 2015, ANDRITZ will increase the capacity of the drying line for bleached eucalyptus kraft pulp to peak values of more than 2,300 tons per day and thus the specific drying capacity to over 470 tons per day and meter of working width.
