International technology Group ANDRITZ has successfully started up a Steel Yankee cylinder and headbox supplied to a customer in Indonesia for a new MG paper machine. With a shell length of 7.4 m, this Steel Yankee is the longest of the world.
In addition to the PrimeDry Steel Yankee and the headbox, ANDRITZ also delivered the core components for the approach system and the dilution water control equipment.
The headbox (PrimeFlow SW) has been newly developed for the use with fourdrinier wires and hybrid formers. With this innovative ANDRITZ technology for paper and board machines, the step diffuser and the lamella nozzle generate micro-turbulence in order to produce optimum formation and evenness of the paper. The mechanical design, manufacturing precision, and the dilution water system (PrimeProFiler F) ensure excellent cross-direction profiles.
