Component Specifications

Definition

A wear liner or insert is a sacrificial component designed to absorb abrasion and impact in discharge chutes, typically made from hardened materials to extend equipment life and maintain material flow efficiency by preventing direct contact between abrasive materials and the chute structure.

Working Principle

Functions as a sacrificial barrier that absorbs kinetic energy and friction from moving bulk materials (such as ores, aggregates, or grains), distributing wear across its surface to protect the underlying chute structure, thereby reducing maintenance frequency and preventing structural failure.

Materials

High-chromium cast iron (e.g., ASTM A532 Class III Type A), hardened steel (400-600 Brinell), ceramic-lined composites, or ultra-high molecular weight polyethylene (UHMWPE) for specific applications.

Technical Parameters

Weight 5-100 kg per piece
Hardness 400-650 HB
Thickness 10-50 mm
Installation Method Bolted or welded
Operating Temperature -40°C to 300°C

Standards

ISO 13521, DIN 22101

Frequently Asked Questions

How often should wear liners be replaced?

Replacement frequency depends on material abrasiveness and throughput; typically every 6-24 months, based on regular thickness inspections.

Can wear liners be customized for specific chute designs?

Yes, they are often custom-fabricated to match chute geometry, with options for different materials and thicknesses based on application needs.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
