Dewatering elements for the press section
Combination of silicium-nitride ceramic and FRP base for an even dewatering profile.
Increased dewatering efficiency Increased open area - more than 65 % Increased fabric lifetime Felt is not sucked into the slot anymore No stretching of the felt (less stress compared to "Z" design) Decreased energy consumption Less vacuum is needed Less air consumption Less friction based on the good support Special feature
Continuous ceramic surface for perfect support of the felt and reduction of friction
Speeds of up to 3,000 mpm – fourdrinier machines for all positions under stress in modern paper machines (from gravitation dewatering)
ROBACERAM X-Ring Cover
Combination of plastic covering and ceramic elements specially for an even dewatering profile. Its unique barbed hooks ensure perfect fastening.
Higher dewatering capacity Larger open area - 65 % increase Longer felt life Felt is not sucked into the slot No expansion of the felt (less stress than in the „Z“ design) Reduction in the driving energy Less vacuum required Less air consumption Less friction due to good support Special feature
Patented: Barbed hooks for guaranteed grip
Felt suction covers in the press section
ROBACERAM Uhle Box Covers
Our covers offer unique safety features and the greatest useable thickness. To guarantee maximum safety, ceramic dewatering elements at Röchling Industrial are specially designed:
Mechanical fixation of the ceramics at the FRP base body Mechanical segment fixation - no piano keying
Therefore different material qualities are available:
ROBACERAM-ALOX Proven material quality for over 20 years High purity of aluminium oxide (99.7%) Surface quality RA 0.3 ROBACERAM-ZIROX Special ceramic for press section Higher thermal shock resistance of 200°K Surface quality RA 0.2 ROBACERAM-SiN Thermal shock resistance of 600°K Better wear resistance Surface quality RA 0.1 ROBACERAM-PX Highest thermal shock resistance of 700°K Maximized wire lifetime Best surface quality RA 0.06 - reduction of friction and therefore reduction of drive power (energy saver)
ROBACERAM Uhle Box Covers
Beside our recommended materials we have more qualities that can be used in the press section as well.
ROBACERAM-ZTA: Increased thermal shock resistance compared to ALOX with 180°K Improved wear resistance Surface quality RA 0.2 ROBACERAM-SL200B Special kind of SiN ceramic Increased wear resistance Very smooth surface roughness RA 0.1 ROBACERAM SiC-Premium Carbide Best wear resistance compared to all materials Thermal shock resistance 400°K Good surface quality RA 0.12
Arrange technical advice
The performance and reliability of components used for paper machines are influenced by a variety of factors. These criteria need to be considered in order to make the right choice. Examples:
Mechanical loading Thermal loading Operating temperature Design requirements Dimensions and tolerances
