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
