Feeder Liners for Severe Abrasion, Bulk Material Flow, Mining, Cement, Coal, and Heavy-Duty Handling Equipment
HALDEN feeder liners are manufactured from chromium carbide overlay wear plate and can be supplied according to your drawings, thickness requirement, fixing method, and working condition. They are designed to protect feeder trays, chutes, hoppers, transfer points, vibrating feeders, apron feeders, and bulk material handling systems against severe sliding abrasion and continuous material impact.
Feeder Liners Wear Fast When Ore, Coal, Clinker, Limestone, Slag, or Aggregate Slides Continuously Across the Surface.
A properly selected chromium carbide overlay feeder liner reduces liner replacement frequency, protects the feeder structure, and lowers downtime cost.
Key Information Needed Before Selecting Feeder Liners
To recommend the right feeder liner, HALDEN needs to know the feeder type, liner drawing, material handled, particle size, impact level, current liner life, installation method, base plate thickness, overlay thickness, and whether the liner requires cutting, bending, drilling, plug-weld holes, countersunk holes, or stud welding.
Feeder Type
Vibrating feeder, apron feeder, belt feeder, chute feeder, hopper feeder, and transfer feeder have different wear concentration zones.
Material Handled
Ore, coal, clinker, cement raw meal, limestone, slag, ash, gravel, sand, and recycled material create different abrasion patterns.
Overlay Thickness
HALDEN can supply many base + overlay combinations, including 3+3, 6+4, 6+6, 8+6, 10+10, 12+12, and other customized sizes.
Installation Method
Feeder liners can be designed for bolting, plug welding, stud fixing, countersunk bolts, direct welding, or custom maintenance access.
What Are Feeder Liners?
Feeder liners are replaceable wear protection plates installed inside feeders, chutes, hoppers, discharge zones, and material transfer equipment. HALDEN feeder liners are commonly made from chromium carbide overlay plate, where hard Cr7C3 carbides are deposited on a medium or low carbon steel base plate to resist severe abrasion.
Weldable Base Plate
Q235 or Q345 backing plate provides structural support, weldability, and installation flexibility for feeder liner packages.
Chromium Carbide Overlay Layer
The hardfacing layer contains a high volume fraction of Cr7C3 carbide, providing strong resistance against abrasive material flow.
Custom Liner Processing
HALDEN can cut, bend, curl, and tailor-weld feeder liners into required shapes according to customized drawings.

CCO Feeder Liner vs Normal Wear Plate
The original page compares HALDEN chromium carbide overlay plate with normal wear plate across chromium content, carbide volume fraction, hardness uniformity, thickness tolerance, flatness, and wear resistance.
| Comparison Item | HALDEN Chromium Carbide Overlay Feeder Liner | Normal Wear Plate |
|---|---|---|
| Chromium Content | Wear-resistant layer chromium content can reach 25–40%. | Common wear-resistant plate chromium content is usually only 10–20%. |
| Cr7C3 Carbide Volume Fraction | More than 50% in metallographic structure. | Less than 30% in ordinary wear-resistant plate. |
| Hardness | High and uniform wear-resistant layer hardness, HRC60–65. | Hardness is not uniform and is less than 60 according to original comparison. |
| Overlay Thickness Tolerance | Uniform wear-resistant layer thickness, tolerance controlled within 0–0.5mm. | Wear-resistant layer thickness is often uneven. |
| Flatness | Plate flatness controlled at 3mm/m. | Ordinary wear-resistant plate can be uneven and seriously deformed. |
| Wear Resistance | Original page states wear resistance is 5–6 times higher than heat-treated wear-resistant steel. | Wear resistance is weaker or may not provide enough wear resistance in severe service. |
