Product Description
At high-impact transfer points, abrasion is only part of the wear
problem. Large particles, high drop heights, and repeated impact
can crack rigid liners or loosen ceramic tiles, while conventional
rubber liners may wear too quickly under continuous material flow.
Elacera® ceramic embedded rubber wear liners combine wear-resistant
alumina ceramics with an impact-absorbing rubber matrix. The
ceramic elements resist sliding abrasion, while the surrounding
rubber cushions impact, vibration, and structural stress.
This design is particularly suitable for chutes, hoppers, bins, and
transfer points handling ore, coal, clinker, slag, and other
abrasive bulk materials.
HOW THE COMPOSITE STRUCTURE WORKS
Wear-Resistant Ceramic Surface
The alumina ceramic elements form the primary wear surface and
protect the equipment from continuous abrasion.
Impact-Absorbing Rubber Matrix
Elastic rubber absorbs part of the impact energy and reduces the
risk of ceramic cracking or detachment.
Embedded Ceramic Design
The ceramics are securely vulcanized into the rubber, protecting
their edges and improving stability under repeated impact.
Optional Steel Backing
For heavy-duty applications, the liner can be supplied with a steel
backing plate, studs, or bolt holes for mechanical installation.
KEY BENEFITS
• Combines abrasion resistance with impact absorption
• Reduces ceramic cracking and liner detachment
• Helps lower vibration and operating noise
• Suitable for curved or irregular equipment surfaces
• Available in customized sizes, shapes, and thicknesses
• Easier to replace than permanently welded steel liners

LINER SELECTION GUIDANCE
Embedded alumina ceramic rubber liners are suitable for equipment
exposed to both abrasive sliding wear and repeated impact.
Before selecting the liner structure, the following operating
conditions should be evaluated:
• Conveyed material and particle size
• Drop height and impact angle
• Material flow rate
• Operating temperature
• Existing equipment dimensions
• Installation and maintenance space
For extremely high impact, large lump materials, or concentrated
direct impact, a ZTA ceramic rubber liner or a thicker ceramic
structure may be more suitable.
CUSTOMIZATION AND INSTALLATION
Elacera® can customize the ceramic arrangement, rubber thickness,
overall dimensions, steel backing, bolt holes, and fastening method
according to equipment drawings.
Bolt-on installation is recommended when fast replacement and
maintenance are required. Steel-backed liners with studs can be
used where stronger mechanical fixing is necessary.
FAQ
Q1: What is the difference between an embedded ceramic rubber liner
and a rubber liner?
The embedded ceramic liner provides a hard, wear-resistant surface,
while the rubber matrix absorbs impact. A rubber-only liner offers
good cushioning but normally has lower abrasion resistance.
Q2: When should ZTA ceramics be considered?
ZTA ceramics are recommended for more severe impact conditions,
especially where large particles, high drop heights, or
concentrated impact may cause standard alumina ceramics to crack.
Q3: Can the liner size and ceramic arrangement be customized?
Yes. The liner dimensions, ceramic shape, ceramic arrangement,
rubber thickness, and fixing method can be customized according to
equipment drawings and operating conditions.
Q4: How are the liners installed?
Common installation methods include embedded bolts, steel-backed
studs, and bolt-on fixing. The appropriate method depends on the
equipment structure and maintenance requirements.
Q5: What information is needed for liner selection?
Please provide the conveyed material, particle size, drop height,
operating temperature, equipment dimensions, wear location, and
installation drawings.
