Installation PositionFixed impact wall outside the rotor on mammut/HUM and some single-shaft machines; item 16 in the HUV variant diagram.
Main FunctionProvides a fixed impact surface and protects the housing.
Replacement FrequencyHigh; assess replacement from thickness, profile, cracks, bolt-hole condition and changes in product size.

Materials and Mechanical Properties

ItemDetails
Material OptionsAISI 1040/1045 carbon-manganese steel, manganese steel, martensitic wear-resistant steel, high-chromium white cast iron or composites
Typical Properties and Acceptance CriteriaImpact wall liners withstand rebounding material and abrasive wear. TerraSource lists hot-rolled 1040/1045 carbon-manganese steel for TKK breaker plates. Higher hardness may be considered in abrasive zones, but toughness remains essential under lump impact and around holes or thin sections. Inspection covers flat or curved profiles, thickness, hole positions, fit, composition, hardness and cracks.
Principal Failure MechanismImpact, cutting and abrasive wear; sliding and three-body abrasion, local impact and cracking around fastener holes

Material and Design Considerations

  • Identify material hardness, particle size, abrasiveness, moisture, temperature, pH, impact and tramp material;
  • High hardness does not replace core toughness, fatigue strength, corrosion resistance or high-temperature performance;
  • For composite, hardfaced, ceramic and elastomer designs, assess substrate bonding, edge protection, fastening and maintainability;
  • For parts that mate with shafts, gears, seals, roll surfaces or housings, control fits, tolerances, surface finish and assembly clearances together;
  • Assess material upgrades using cumulative throughput, dimensional wear, failure modes, product quality and downtime costs.

Required Ordering / RFQ Information

  • Equipment manufacturer, machine model, serial number, part number and latest drawing revision;
  • Part dimensions, unit weight, key tolerances, assembly and fastening method;
  • Current material, chemical composition, heat treatment, hardness and mechanical property reports;
  • Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
  • Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
  • Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
