By component

The complete liner package

A reline is stopped by the smallest part you do not have. We cast the whole set to one drawing package so everything arrives together and fits together.

LHCLQM® MILL LINERSSHELL LINERS

Shell Liners

The largest tonnage in any liner set. Sections profiled to suit charge trajectory; material chosen for the wear mechanism in that chamber.

5 × SEGMENTQM® MILL LINERSHEAD LINERS — FEED END

Head Liners — Feed End

Where the ore lands. Toughness matters more than hardness, which is why these are usually manganese.

5 × SEGMENTQM® MILL LINERSHEAD LINERS — DISCHARGE END

Head Liners — Discharge End

Impact and slurry erosion combined. Often the position that limits reline interval.

L7 × SLOT 20QM® MILL LINERSGRATE PLATES

Grate Plates

Slot size and open area control pulp discharge. Wear widens the slots, so the steel has to hold its shape.

HSECTION A–AQM® MILL LINERSLIFTER BARS

Lifter Bars

The component that decides how the charge moves. Profile is set by your drawing; we cast it accurately so it behaves as intended.

HSECTION A–AQM® MILL LINERSPULP LIFTERS

Pulp Lifters

Sliding abrasion at its worst. Frequently replaced before the surrounding shell liners are worn out.

Ø ID / ODQM® MILL LINERSTRUNNION LINERS

Trunnion Liners

Often overlooked until it fails. Cast to drawing with bore and flange dimensions matched to your trunnion.

LHCLQM® MILL LINERSMILL DOOR & WEDGES

Mill Door & Wedges

Door plates, wedge blocks and fasteners cast to match the liner set so assemblies fit first time.

By industry

Where our liners are working

We cast wear parts, not just catalogue items

If a part in your mill wears out, there is a good chance we can cast it — as long as you have a drawing, or a worn part we can measure. Chute liners, hopper liners, crusher wear plates and custom castings are all part of normal production.
