What are composite liners?
Composite liners are hard ceramic wear-protection components made from alumina or silicon-carbide ceramic combined with rubber, polyurethane or epoxy, used to protect equipment from abrasive and impact wear. A ceramic wear face is bonded to rubber, polyurethane or epoxy, marrying hardness with impact absorption. In mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants, they extend equipment life and cut maintenance.
What are composite liners used for?
They line chutes, hoppers, bunkers, mills, pulleys and conveyor transfer points where bulk solids or slurry scour metal away. Typical users are mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
What material and properties make composite liners effective?
A ceramic wear face is bonded to rubber, polyurethane or epoxy, marrying hardness with impact absorption. These properties let composite liners outlast steel and rubber in abrasive service.
Why choose composite liners over steel or rubber alternatives?
Composite liners beat plain metal, rubber or polymer on abrasive duties: steel erodes in months and can contaminate product, while rubber gouges under lump impact. Composite liners hold dimension, cut downtime and typically last 5–10× longer in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
How do I select and specify composite liners?
Pick tile grade (92%/95%/99% alumina, ZTA or SiC) and backing (steel-stud, rubber-embedded or adhesive) to your wear mode, then send equipment drawings so FIRSTAR supplies matched tiles or panels.
Can composite liners be installed on curved surfaces?
Yes. Mosaic and hex ceramic mats conform to curved chutes, pipes and cones, while flat tiles suit hoppers and bins. FIRSTAR provides the right shape and backing for your profile.
