Ceramic-backed chute liners for high-impact transfer points
Ceramic resists abrasion. Rubber absorbs impact. At a transfer point you usually need both, in the right order.
Liner selection at a transfer point tends to get argued as a binary — ceramic or rubber — when the failure modes at either end of a chute are completely different and call for different answers.
Two problems, two materials
At the impact zone, material arrives with energy that has to go somewhere. Ceramic tiles in that position crack, because ceramic is hard and brittle and impact is exactly what it does not tolerate. Rubber absorbs the energy and survives.
Further down the chute, where material is sliding rather than landing, the problem is abrasion. Rubber wears steadily. Ceramic barely notices.
The composite answer
A ceramic-backed rubber liner puts a rubber layer in front of a ceramic substrate, so impact energy is absorbed by the elastomer before it reaches the tile, while sliding abrasion is carried by the ceramic. It costs more than either material alone and it outlasts both in the position where it belongs.
It is not the right answer everywhere. On a low-energy transfer with fine material, plain rubber or UHMWPE is cheaper and lasts long enough. We size liner specification against measured impact energy rather than a rule of thumb, and it is worth asking for that calculation before committing to a full chute in composite.
