ROBALIT 61^® dewatering elements

ROBALIT 61<sup>®</sup> dewatering elements

The world's first UHMW-PE
dewatering element is known for its high
dry-film lubricant content.
This produces an extremely smooth surface,
most importantly resulting in a low friction
coefficient a low level of adhesion.

No adhesion
Excellent chemical resistance
Low coefficient of friction

Manufacture

All materials are produced through lengthy sinter pressing processes with extremely long press cycles.
This enables us to produce covers up to 12 m long with no welding seams and also ensures a tension-free
internal structure compared with the typical standard sinter press process and extrusion.

Assembly

PE dewatering elements for paper machines have a high level of thermal expansion. They must therefore be installed in such a way that enables the strips or covers to expand without restriction (T-bars, corner strips, dovetail guides, screws in elongated holes). The base frame support must have a grid of approx. 250 mm to ensure flawless functionality for our covers. This support must extend to the underside of the cover to ensure it has a flat installation surface.
