  • ROBACERAM dewatering elements
  • Dewatering elements made of ceramics

    Ceramic dewatering elements are much more wear resistant than their plastic equivalents. There are many different materials available, all of which can be tailored to meet customer requirements (machine speed, filler content, etc.). ROBACERAM dewatering elements made of ceramics are suitable for all machine speeds.

    Special features

    This dewatering elements have a useful ceramic thickness of up to 8 mm

    Safety features

    Supply range

    ROBACERAM-PX

    Ceramics for the paper industry – especially hard and smooth hybrid ceramics for positions under significant stress.

    • Increased fabric lifetime (excellent surface quality)
    • Energy saving (reduced power consumption)
    • Safety ceramic (thermal shock resistance of 700°C)
    • The most wear-resistant ceramic

    Carbon fibre cross-beam

    Due to the enormous energy saving which shows the high quality PX-ceramic especially at HighVac covers, the innovative carbon fiber cross-beam are perfect for that application. They prevent, even at high vacuums of up to 70 kPa, a bending of the cover!

    Application

    Speeds of up to 3,000 mpm – for all positions under high stress in modern paper machines, especially areas with a high vacuum.

    ROBACERAM SiC-Premium Carbide

    Liquid-phase sintered premium silicon carbide with extremely good wear resistance.

    • Good surface finish
    • Liquid-phase sintered, therefore less brittle
    • High hardness 

    Application

    Speeds of up to 3,000 mpm – fourdrinier machines for all positions under stress
    in modern paper machines (from gravitation dewatering)

    ROBACERAM-SL200B

    Special nitride with further improved surface quality and increased hardness.

    • Extremely high thermal shock resistance of 600°C
    • Increased wear resistance
    • Extremely high resistance to edge breaks
    • Impressive fabrics lifetime
    • Very good surface quality

    Application

    Speeds of up to 3,000 mpm – for all positions under high stress in modern paper machines, especially areas with a high vacuum.

    ROBACERAM-SIN

    Highly rated nitride ceramic with needle-shaped grain structure and excellent surface quality.

    • Extremely high thermal shock resistance of 600°C
    • Good wear resistance
    • Tough material
    • Good surface quality  

    Application

    Speeds of up to 800 mpm – GAP formers
    Speeds of up to 1,500 mpm – fourdrinier machines for all positions under stress in modern paper machines (from gravitation dewatering)

     

    ROBACERAM-ZIROX

    Extremely "soft" special ceramic made from zirconium oxide. Primarily used in press sections.

    • Tough material
    • Enhanced thermal shock resistance of 200°C
    • Low porosity

    Application

    Speeds of up to 800 mpm – for the press section
    Not recommended for former elements

    ROBACERAM-ZTA

    Special ceramic for special applications e.g. with a higher filler content.

    • Improved surface quality
    • Small grain size
    • Enhanced thermal shock resistance of 180°C

    Application

    Speeds of up to 800 m/min – entire wire section
    Speeds of up to 1,200 m/min – from the forming board to the water line
    Vacufoils & formers, flat suction units with a higher filler content

    ROBACERAM-ALOX

    High-quality technical aluminum oxide ceramic offering the best price-performance ratio.

    • Quality proven for over 20 years
    • Good wear resistance

    Application

    Speeds of up to 800 mpm – entire wire section
    Speeds of up to 1,200 mpm – from the forming board to the water line
