Cera-Wear HR BB Ceramic Wear Pads are a premium grade wear and corrosion resistant composite ceramic liner with a CN bonding layer
FEATURES
Cera-Wear HR BB Ceramic Wear Pads are made from wear resistant 92% alumina ceramic tiles embedded within a corrosion resistant rubber matrix. They display excellent resistance to both high velocity and high flow wet slurry and fine particle sliding abrasion and impact.
These ceramic liners feature interlocking hexagonal shaped ceramic tiles completely vulcanised within a 50 Duro premium bromo-butyl rubber compound. This hexagonal shape combined with the rubber between the tiles gives maximum impact resistance and flexibility for installation on flat, convex or concave surfaces.
The bromo-butyl rubber compound used between the tiles gives Cera-Wear HR BB Ceramic Wear Pads high temperature and excellent chemical resistance to both acids and alkalis.
They also feature a specially formulated neoprene based CN bonding layer to achieve ultimate adhesion when bonded to steel or rubber surfaces. The CN bonding layer is compatible with a wide range of neoprene based rubber adhesives and allows for good bond strength to be achieved even in adverse conditions encountered on site.
APPLICATIONS
Cera-Wear HR BB Ceramic Wear Pads have been designed primarily for use as a wear protection ceramic lining system in highly corrosive environments.
They are suitable for applications with exposure to high temperatures and a wide variety of chemicals.
These ceramic wear pads are bonded to equipment to protect steel surfaces from abrasion and impact. They are predominantly used in the mining, quarrying and mineral processing industries, typically on the following equipment:
- Chutes
- Tanks and Pipework
- Conveyor Loading and Transfer Hoods
- Feeders
- Screen Beams and Components
- Cyclones
- Launders
- Floatation Cells
- Mill Feed Chutes
- Sumps and Underpans
