Discharge Chute Liners

Guides the crushed product and protects the discharge chute structure.

Discharge Chute Liners (Discharge Chute Liner)— Hammer Crusher Wear part, position 21.

Installation and Function

Installation PositionBelow the grates and in the discharge passage at the bottom of the crusher; position 21 in the HDS/HUV layout.
Main FunctionGuides the crushed product and protects the discharge chute structure.
Replacement FrequencyMedium to high replacement frequency; assess local gouging, remaining thickness, detached areas, cracks and material build-up.

Materials and Mechanical Properties

ItemDetails
Material OptionsQuenched and tempered wear plate in the 400–500 HB range, high-chromium overlay plate, ceramic/rubber composites or polyurethane
Typical Properties and Acceptance CriteriaSelect materials by zone, considering particle velocity, impact angle, moisture, temperature and material build-up. High-chromium overlay and ceramic options offer abrasion resistance but require adequate support, edge protection and controlled impact. Brittle, very hard materials require particular care at the first impact point. Consider friction so improved wear resistance does not cause blockages.
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.
