Newark mill’s upgrade to use OCC recycled material
has been completed by Voith to reduce production costs and boost process efficiency. Following the upgrade
A
at Newark’s Fitchburg, Massachusetts, mill it can now use OCC (old corrugated containers) instead of less-contaminated recycled board as a raw material for the production of high- quality linerboard. In addition, the upgrade ensures the least fibre loss during the production process. “We are very pleased with the
upgrade at our Fitchburg facility,” said Barry Jensen, vice president at Newark Recycled Paperboard Solutions. “The upgrade process
n upgrade of the stock preparation at US- based Newark Recycled Paperboard Solutions
went according to plan and the start-up was the smoothest we have encountered, which is even more impressive considering complexity of the project. Within a few hours of pressing the start button, the plant was supplying the machine with quality fibre at design capacity. The upgrade project has met all the quality objectives, and power consumption is lower than expected.”
The main upgrade consisted of improving the current pulper detrashing loop using Voith’s IntensaMaxx which prevents tail formation and spinning so that even content with high levels of contaminant can be easily processed. It can be used in continuous low consistency (LC) pulping with recovered paper
Reject handling system handles 200 tons a day
A complete reject handling system has been ordered from Andritz by Shandong Sun Paper Industry in China. The system that will be used on the paper maker’s PM31 and PM32 machines includes coarse and fine shredding systems, a ballistic separator, reject compactors, sand separators, as well as coarse and fine metal separators, including ferrous and non-ferrous metal separation. The reject handling system has a
total capacity of about 200 tons of light rejects per day. The residuals

from both recycled fibre lines will be prepared for combustion or for further cleaning and recycling, while valuable components like metals will be separated. Start-up is scheduled for the second quarter of 2016.
grades containing contaminants or in high consistency (HC) pulping as a dumping machine after the batch HC pulper. In addition, Newark Fitchburg
upgraded a multi-stage fine cleaning system with Voith’s HCL5C cleaner with HW and LW removal combination, while adding a three- stage fine screening upgrade with the C-bar screen basket. These upgrades included a new third- stage MultiMizer with optimum slots configuration. The HCL5C technology is a multi-stage system for cleaning fibre suspensions. It removes heavyweight and lightweight contaminants in the stock preparation and approach flow systems. The C-bar screen basket is used in stock preparation and approach flow and can be used for
increasing the capacity of existing pressure screens. It has a large open screening area with high slot width precision, providing up to 20 per cent more capacity than conventional screen baskets. The MultiMizer improves the overall system performance and provides cost savings by reducing the amount of flakes in the reject stream of the fine slotted screening system. New Jersey-based Newark, originally The Newark Group, was founded in 1912. In 2013, Newark became Newark Recycled Paperboard Solutions and is the largest open-market seller of recycled paperboard in North America. Newark operates six mills that produce more than 450,000 metric tons of 100 per cent recycled paperboard each year.
Andritz tissue machine for Guangdong Shaoneng
Leading Chinese pulp and paper producer Guangdong Shaoneng Group has ordered an Andritz PrimeLineCOMPACT II tissue machine with steel Yankee for its mill at Shao Guanin Guangdong province.
The machine will have a design speed of 1,600 m/min, a width of
2.85m and will be supplied with a complete stock preparation plant, automation, and drives. Bamboo pulp produced at the mill will also be used in tissue production. Start-up is scheduled for the end of 2015.
