CERA-WEAR HR BB Ceramic Wear Pads are a premium grade, composite liner of wear resistant 92% alumina, hexagonal ceramic tiles vulcanised within a corrosion resistant Bromo-Butyl rubber, which has excellent resistance to both high speed wet slurry and fine particle sliding and high flow impact abrasion. They also have high temperature and chemical resistance to acids and alkalis.
CERA-WEAR HR BB Ceramic Wear Pads are supplied with a specially formulated Neoprene based CN Bonding Layer to achieve the ultimate adhesion when bonded to steel or other rubber surfaces. To achieve this ultimate bond strength, the TRS range of cold, vulcanising adhesives are recommended.
CERA-WEAR HR BB Ceramic Wear Pads are supplied with the tiles completely embedded within a rubber matrix to increase the bond strength of each individual tile within the pad. The hexagonal shape combined with rubber between the tiles gives maximum impact resistance and flexibility for installation on flat, convex or concave surfaces, making them suitable for wear and corrosion protection in corrosive applications.
The CN bonding layer and TRS adhesive system is extremely flexible and allows a good bond strength to be achieved, even in adverse conditions often encountered when application is occurring on site on operational equipment.

Ceramic Wear Pads can be supplied as an individual panel or as a custom element ready for mechanical installation. They can be supplied as per specifications and drawings or custom designed to meet your requirements.
CERA-WEAR HR BB Ceramic Wear Pads have been designed primarily for use as a ceramic lining for the wear and corrosion protection of steel equipment. These tiles are mainly used for high speed, wet abrasion applications such as slurry handling in the mineral processing industry but can be used for any fine particle abrasion applications.
Typical equipment to be lined includes:
- Pipes and tanks
- Loading and transfer hoods
- Screen feed boxes
- Screen Beams and components
- Valves and pumps
- Flotation Cells
- Mill feed Chutes
- Sumps and underpans
- Grain handling and processing equipment
