Grate basket / grate frame

Name: Grate basket / grate frame
Brand: ANRANST

Supports the screening surface, maintains curvature and working clearance, and allows the frame to be withdrawn for maintenance.

Grate basket / grate frame (Grate Basket / Grate Frame)— Hammer Crusher Wear part, position 14.

Installation and Function

Installation Position	Below the rotor, around the grate bars and segments; position 14 in the location and internal exploded diagrams.
Main Function	Supports the screening surface, maintains curvature and working clearance, and allows the frame to be withdrawn for maintenance.
Replacement Frequency	Low to moderate wear exposure; assess repair or replacement for deformation, cracks, worn support grooves or inability to maintain grate openings.

Materials and Mechanical Properties

Item	Details
Material Options	High-strength cast steel or welded structural steel, with replaceable wear parts on working and support surfaces where required
Typical Properties and Acceptance Criteria	The grate frame supports the grate bars and segments. It needs adequate yield strength, stiffness, impact toughness and weld quality. Check curvature, support grooves, locating faces, split interfaces, weld NDT, deformation and safe rotor clearance. Brittle high-chromium material is not a direct substitute for the supporting frame.
Principal Failure Mechanism	Impact, cutting and abrasive wear; enlarged openings, blockage, 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.
