It’s made of alumina in hemisphere shape embedded in

special rubber and backed with rubber & steel plates. The

hemisphere design make it very effective to reduce to

impact of materials as well as maintain the good wear-

resistance. It’s a ideal solution to protect equipment in

the field of strong impact & wear by big block materials,

such as chutes, hoppers, buckets and silos in sectors of

mining, cement, steel plants and ports.

KINGCERA the power to resist wear

Wear liners comprise of alumina ceramic tiles, moulded in a high tensile strength

natural rubber matrix, and mounted on steel backing plates. All rubber ceramic

liners are hot vulcanized together using specialized equipment which provides a

bond strength that exceeds the tensile strength of the natural rubber matrix. As a

result the ceramics will remain in the rubber matrix, offering consistent wear

protection across the entire life of the liner.

Easy adaptation into existing

installations is achieved with the

modular liner layout comprising of

standard sizes and studs welded to a

6mm steel backing plate, or to other

thickness plates as requested. This

steel backing plate provides rigidity

for easy replacement and standard

sized liners are produced for

convenience.

Application:

• Deflectors/Impact plates

• Chutes

• Bins/Hoppers

• Skirt liners

• Stackers & Reclaimers

• Clear advantages:

---Increased productivity

---Enhanced wear characteristics

---Improved flow efficiency

---Noise reduction

As a leading wear-resistant ceramic manufacturer, we’re the first and only

developer of ZTA liner (Zirconia-toughened alumina) in China.

As we know, alumina ceramic is 8 to 10

times higher on wear resistance than

metal plates. Based on the practical test

on some giant mines in Australia, our ZTA

liner is proven to be nearly 2.5 times

higher than Alumina liners. Such excellent

anti-wear ability makes ZTA the ideal

material to protect the equipment

wherever suffering the extreme wear

particularly in power plants, cement

plants, mines , ports and etc.

By using the ZTA, equipment life time is

largely extended and the costly

downtime for maintenance is avoid.
