Chute Liners
Alien composite wear technology
Alien is a next-generation wear liner material engineered for high-impact, high-abrasion zones such as mill feed chutes and transfer points. The composite matrix fuses high-chrome white iron with zirconia-toughened alumina (ZTA) ceramics, delivering superior resistance to abrasion, extreme loading and crushing forces — where conventional white iron liners wear out fastest.
Liners are custom shaped to your chute geometry — down to radiused bases — for a precise fit and optimal material flow. The result is longer service windows, fewer change-outs and wear maintenance that happens on the schedule you plan, not the one the chute dictates.
Field-proven performance
At a copper/gold operation, Alien liners lifted chute wear life to the targeted 12-month change-out interval, avoiding losses tied to unplanned downtime estimated at ~$3M per day of stoppage.
Why choose Alien composite liners
- Hybrid matrix — high-chrome white iron for impact, ZTA ceramic for abrasion, in one liner
- Outlasts conventional white iron in aggressive chute applications
- Tailor-made geometries including complex radii, for efficient retrofits and improved flow
- Fewer change-outs — less maintenance exposure, lower cost per tonne
Frequently asked questions
Where do Alien liners perform best?
Mill feed chutes, transfer points and any zone combining heavy impact with severe abrasion — conditions that defeat plain ceramic (too brittle) and plain white iron (wears too fast).
Can liners be made for our existing chute?
Yes — Alien liners are custom shaped to your geometry, including radiused bases, so retrofits fit precisely without chute modification.
How does Alien compare to rubber-ceramic liners?
Rubber-ceramic matrix liners (such as those in our Richwood transfer chute packages) excel where impact absorption matters most; Alien suits the extreme end of combined crushing load and abrasion. We’ll recommend the right liner for each zone.
