Grate basket trolley rollers and guides

Name: Grate basket trolley rollers and guides
Brand: ANRANST

Supports grate basket withdrawal, reinstallation and positioning for grate maintenance.

Grate basket trolley rollers and guides (Grate Basket Trolley Roller and Guide)— Hammer Crusher Wear part, position 15.

Installation and Function

Installation Position	Withdrawal trolley below the grate basket and guides in the housing; item 15 in the location and internal exploded diagrams.
Main Function	Supports grate basket withdrawal, reinstallation and positioning for grate maintenance.
Replacement Frequency	Medium; inspect and replace affected parts if rollers seize, treads spall, bearings fail, guides wear unevenly or positioning is lost.

Materials and Mechanical Properties

Item	Details
Material Options	Materials such as 42CrMo/C45 for axles and surface-hardened wheels, wear-resistant guide steel and rolling-bearing steel
Typical Properties and Acceptance Criteria	Trolley parts must carry the grate basket weight under contamination, uneven loading and low-speed rolling contact. Control wheel diameter, tread hardness, bearings, axles, guide straightness and parallelism, locking and load distribution. Local hardfacing must not cause tread spalling or uneven guides. After maintenance, verify the operating-position lock and safe rotor clearance.
Principal Failure Mechanism	Impact, cutting and abrasion; contact fatigue, surface wear, thermal cracking or spalling; aperture enlargement, plugging, erosion and fatigue.

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.
