Return rollers

Return rollers in composite give a weight reduction of up to 80% compared to equivalent steel rollers.

Narvik Composites` return rollers are developed and tailormade for the challenging conditions that are found in the mining industry in Scandinavia.

The construction of the return rollers in composite coated with a 5mm. wearing layer of Polyurea makes the roller not only light in weight, but also extremely durable and robust.

The weight of a composite return roller is surprisingly low; a weight reduction of up to 80% compared to an equivalent steel roller. This gives the composite roller an enormous advantage when replacing rollers, in both time and resources.
