Hammers

Directly impacts and shears material, then throws it towards the central anvil, breaker wall or grinding path.

Hammers

Hammers (Hammer / Swing Hammer)— Hammer Crusher Wear part, position 01.

Installation and Function

Installation PositionAround the rotor, swinging freely on through-mounted hammer shafts; position 01 in the twin-shaft internal exploded view and HDS/HUV layout.
Main FunctionDirectly impacts and shears material, then throws it towards the central anvil, breaker wall or grinding path.
Replacement FrequencyVery high replacement frequency; turn or replace according to tip wear, bore clearance, cracks, weight matching and wear consumption per tonne.

Materials and Mechanical Properties

ItemDetails
Material OptionsAlloy steel forgings using grades covered by ASTM A322, high-manganese steel, martensitic wear-resistant steel, a high-chromium working layer, or a bimetallic design combining a tough shank and wear-resistant hammer head
Typical Properties and Acceptance CriteriaSelect hammers for impact, abrasion and tramp-material risk. High-manganese steel commonly starts around 180–240 HB and relies on impact work-hardening. Martensitic steel can balance hardness and toughness around 40–55 HRC. High-chromium working layers are commonly around 55–65 HRC and suit highly abrasive zones only where impact is controlled. Bimetallic hammers must retain toughness at the bore and shank. Verify interface bonding, composition, heat treatment, hardness gradients, UT/MT and individual mass.
Principal Failure MechanismImpact, cutting and abrasion

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.
