CUMI manufactures weldable and pastable alumina ceramic tiles that can be bonded onto the surface that is to be protected from wear.
We can supply the lining in the form of pre-engineered tiles and segments to match the profile of your equipment. These can be easily installed into your existing equipment and piping. We can also supply ready-to-fit ceramic lined equipment, such as pipes, bends, feed chutes, cones and other components.
Bulk material movement involving sliding often causes heavy wear to the equipment, resulting in damage of the equipment, lower reliability, production losses, and lower capacity utilisation. Installation of ceramic liners is a solution, and is a necessity in today’s competitive world where equipment availability and low operating costs are essential.
Based on your applications CUMI manufactures weldable, pastable, rubber backed and dovetail alumina ceramic tiles that can be bonded on to the surface that is to be protected from wear.
Apart from standard sizes, we offer pre-engineered tiles to suit specific equipment. 3D modeling is used to ensure a good fit for the contours of the lining surface.
CUMI can also offer a range of pre-fabricated Ceramic Lined Process Equipments in cases where drawing is provided.

CERAMIC IMPACT PADS
CUMITUFF™ Ceramic rubber composites are manufactured by hot vulcanizing the high alumina ceramic inserts into rubber. The alumina ceramic provides extreme resistance to wear while the elastic properties of the rubber effectively dampen the impact. The resultant composite is ideal for impact and wear protection systems in bulk material handling.
The state-of-the-art plant to manufacture high alumina ceramics and latest vulcanizing plant makes CUMI the largest manufacturer of ceramic rubber composites in India.
Based on severity of application, CUMI offers wear limiting products in 90% and 92% alumina.
CUMI offers various fixing options based on the application requirements, including cold vulcanizing bond, as well as composites with a mild steel backing plate having studs to facilitate easy installation.
