In a recent upgrade, the Cartiere del Garda mill successfully replaced a conventional tape turn-up device with Metso's WaterJet turn-up system. Cuts performed using WaterJet are clean and precise, which ensures an excellent base from the very first spool wrap. WaterJet has the ability to improve turn-up efficiencies and reduce bottom waste on all grades of paper. The Cartiere del
Metso new press section coating family, PressJade, consists of PressJade D, PressJade W and PressJade F ceramic coatings that are engineered for specific paper and board grades. The novel nanomaterials technology behind the new PressJade family improves the long-term runnability of center rolls and cuts maintenance costs because of improved stable surface roughness and reduced wear.
Continuously increasing demands are forcing mills to push their board machines to their maximum limits. This makes it hard to keep a balance between high productivity, good quality and running into breaks that cause unnecessary downtime.
Stora Enso's Kvarnsveden mill has installed closed loop controls that coordinate primary and secondary arm movements during reel turn-ups, and provide even nip-loading and sheet tension during the reel building process. Previous winder break problems are eliminated.
The Santa Maria paper mill in Brazil is carrying through with a multiyear strategy to increase the level of automation, quality control and information accessibility on its two paper machines. The phased plan included the installation of a PaperIQ system on PM1 in 2001and the most recent installation of a PaperIQ Plus system with CD profilers and controls on PM2
Dedication to innovation and quality has empowered the French group ABK to supply to one of the biggest fluting & liner manufacturers worldwide, for one of its paper mills in Indonesia, a new and high- tech press section made of suction bi-nip and shoe press which characteristics can guarantee a...
The increased use of fast growth tropical hardwoods has led to a significant increase in issues relating to vessel picking. Hardwood pulps contain vessel elements, large diameter cells which function to transport water throughout the tree. Different HW species will have different quantities (and sizes) of vessel elements ranging from less than 10% to greater than 50% by volume. These
1.0 Introduction Chemical Recovery Process is used to meet the following objectives in an integrated paper mill: (i) To treat and dispose waste liquor generated from pulp mill, thereby reducing the environmental pollution. (ii) To recover the alkali used for pulping, thereby reducing fresh alkali consumption (iii) To burn the organic matter and beneficially use the thermal energy for the
A partnership between UBC (University of British Columbia), government and the pulp and paper industry has resulted in the development of three high efficiency pulp screen rotors that produce high quality paper while reducing almost half the energy required.
Paper is an essential commodity with which all of us are very closely associated in our daily life. Its socio-economic importance in the overall development of the country has its own value, which is directly linked with the industrial and educational growth in the country.
