Erosion resistance (impacts)

Most ceramics are in general strong, hard and durable which make them attractive structural materials in many plants.But the one significant drawback is normally their brittleness.For Densit® brittleness has been eliminated.

Advantages of Densit product

The Densit® wear protection products can be varied to achieve specific characteristics requested in the different applications .

Temperature: < 400°C... < 800°C… or max 1200°C

Densit® wear resistant linings will provide your equipment with the following advantages:

Increased production - reduced wear causes less downtime.

Less unexpected stops - due to better predictability in life time.

Reduced running costs - less wear reduce false air giving lower load on fans.

Reduced maintenance costs - due to fewer and shorter repairs per year.

Cleaner environment - because a tighter system reduce dust emissions.
