Every worn surface does not need to be lined, however items that are lined will outlast bare steel by many times.
Angular Dry Bulk Solids
The above photograph shows an Abrasion Resistant Lining made from ceramic or hardened polymer that has been fitted to wear points on a conveyor belt. This lining sits between the material being carried on the conveyor belt and the substrate of the conveyor belt. The lining allows the wearing surface to wear instead of the steel from the conveyor belt.
High-Velocity Pneumatic Conveying
Fast moving air laden with fine particles travelling in dry bulk pneumatic conveying systems often erode pipe work especially around bends, off takes and changes in direction. By using ceramic tile lining on all elbows and straights the rate of erosion is greatly reduced, thus extending the period between maintenance.

Coarse Slurry Pipework
Mixes of coarse solids in a wet slurry solution can lead to a combination of abrasion and wet corrosion – a combination that rapidly attacks bare steel. Options are available for this type of wear – contact Kingfisher Industrial for more information on a suitable lining solution.
High-Impact Chute and Hopper Zones
Chute and Hopper Wear Surfaces subject to impact from dropping bulk material undergo rapid steel removal by subsequent abrasion. As opposed to harder wear faced materials, rubber is often a preferred wear liner for such high impact locations, as they absorb the initial shock of impact as opposed to trying to resist it.
For all of these materials it will generally prove more cost effective to line out key vulnerable areas of your plant rather than repeatedly replacing worn out steel.
