Next generation screening performance from ANDRITZ


been launched. Tested in demanding OCC applications, the PrimeScreen X is said to show significant improvements in energy efficiency, screening performance and maintainability. Andritz has installed 5,400


T


pressure screens in mills around the world, and the latest design includes new benefits: ● Top-feed stock inlet. The top- down design takes advantage of gravity to remove heavy contaminants quickly and minimise wear on rotor and screen basket. Top-down also improves the removal of light rejects, preventing the accumulation in the feed area, which again extends the life of wearing components.


● New PrimeRotor and foil design: The PrimeScreen X can be equipped with the new PrimeRotor, which improves screening efficiency and

reduces energy consumption by up to 25 per cent compared to a competitive screen in a comparable application. The PrimeRotor foils are interchangeable with any other Andritz foils and the rotor could be installed in any screen type available on the market.


Consistent and uniform cleaning


High fibre retention and uniform dewatering are key factors of performance in the forming and press sections of a tissue machine. Voith’s CleanLine Excell is claimed


to clean the surface and structure of forming and press fabrics more effectively than oscillating high-

pressure needle jet showers or standard traversing showers. Developed especially for tissue machines the CleanLine Excell cleaning head provides greater fabric permeability retention which leads to better uniformity, less water and energy consumption.


● Easier maintenance: The design of the new rotor attachment and basket fixing results in reduced downtime, as maintenance and replacement of rotor and basket is quick and easy.


● Enhanced geometry: The optimised screen basket height- to-diameter ratios comply with


the requirements of different furnishes and applications, helping to reduce the thickening factors and leading to a better control of fibre loss.


● Versatile in application: The PrimeScreen X is suited to all screening applications independent of the raw materials.
