(Dewatering Ceramic Elements Produced by Wintrustek)

A dewatering system is an essential part of any paper mill. It helps to remove water from the paper pulp so that the paper can be made into sheets. Dewatering elements made of ceramic are significantly more wear-resistant than those made of plastic. There are some kinds of dewatering ceramics:

SiC

High-quality, liquid-phase sintered silicon carbide with excellent wear resistance.

Advantages

• Satisfactory finish

• Less brittle since it is sintered in the liquid phase

• Extreme hardness

Applications

Modern paper mills may operate at speeds of up to 3,000 mpm using fourdrinier machines in all stressed positions (due to gravitational dewatering).

SIN

Nitride ceramic that has a high rating, a needle-like grain structure, and good surface quality.

Advantages

• 600°C of extremely strong thermal shock resistance

• Excellent wear resistance

• Strong construction and good surface quality

Applications

800 mpm and above - GAP formers

Fourdrinier machines with speeds up to 1,500 mpm for all stressed places in contemporary paper mills (from gravitational dehydration)

ZrO2

Extremely "soft" unique zirconium oxide ceramic. used mostly in press sections.

Advantages

• Durable materials

• 200°C enhanced thermal shock resistance

• Low porosity

Applications

800 mpm is the maximum speed limit for the press area

Not advisable for previous ingredients

Al203

Aluminum oxide ceramic with the best price-performance ratio is of the highest caliber.

Advantages

Excellent wear resistance

Applications

• 800 mpm is the maximum speed for the full wire portion

• Up to 1,200 mpm at speeds ranging from the forming board to the water line
