More pulping systems for Nine Dragons in China


ordered two Andritz chemi- thermomechanical pulping systems for its mills. Pre-conditioning refiner chemical alkaline peroxide mechanical pulp (P-RC APMP) technology will be used to ensure optimum pulp quality at lowest energy consumption and highest availability. The fibrelines will have a capacity of 1,000 admt/d and 670 admt/d, respectively, and will process a mixture of eucalyptus, acacia and poplar wood chips for the production of folding boxboard (FBB). The main equipment – from chip washing to the storage tower – for both fibrelines will be supplied by Andritz, and will feature:

Rebuild for Emami’s PM3 line in India


India’s Emami Paper Mills is having a metering size press with sizing starch preparation and sizer supply system delivered by Valmet. The delivery, for Emami’s PM3 paper making line at the Balasore mill in Odisha, is expected in the fourth quarter of 2021, and includes an air turn unit with an air system, a tail threading system including tail cutters, a vacuum conveyor F, a rope stretcher and rope drives with extended engineering services

and training services. After the rebuild, PM3 will


have a 3,560mm wire width and produce papers in the basic weight range of 45-90 g/ sqm. Running at between 900 and 1,100 metres a minute, the machine’s daily capacity will be up to 275 tonnes. “We chose Valmet for their superior technology and look forward to working closely with them to make this project a success,” says M B S Nair, president of Emami Paper Mills.


system for optimum fibre development and lowest shive levels


● Low-consistency (LC) refining stages with TwinFlo refiners for low specific energy


● Four newly-developed PrimeFilter D disc filters for fibre recovery and thickening. The innovative disc filters feature the so-called HHw (high consistency, high freeness, wider space between discs) technology for advanced feeding and optimum flow conditions within the filter as well as CC bagless sectors for advanced operation and reduced maintenance. The start-ups are expected in spring and summer 2022. Andritz has also been supplying pulp production systems to a number of mills operated by Nine Dragons, which produces linerboard, high-performance corrugating medium and coated duplex board as well as printing and writing paper.


Voith paper machines ordered by Nine Dragons


Three Voith XcelLine paper machines for the production of high performance testliner and white top testliner have been ordered by Nine Dragons in China. The identical machines will each


have capacity to produce 2,400 tonnes a day running at 1,400 metres per minute. They will be equipped with a DuoFormer DII E, which enables the speed to be achieved with high basis weights. The press sections include a Triple NipcoFlex press, to ensure good surface smoothness of white top liner. Due to the double unwind configuration and a fully


automated full reel change, the high-performance TwinDrive winder enables fast and efficient winding and thereby ensures a winder capacity that is up to 20 per cent higher than conventional unwinding systems.


Commissioning of the machines is planned for 2022 and 2023. Voith recently started up five BlueLine OCC stock preparation lines for Nine Dragons Paper, each with capacity of 2,000 tons per day, and a sixth line is planned for 2022. In May Nine Dragons ordered pulp


production equipment for five of its mills from Andritz.
