Concave support ring

Name: Concave support ring
Brand: ANRANST

Supports the concave segments, transmits loads and maintains the crushing chamber position.

Concave support ring (Concave Support Ring)— Gyratory Crusher Wear part, position 24.

Installation and Function

Installation Position	At the support position below the concaves; position 23 in the FLS section diagram annotated on this website.
Main Function	Supports the concave segments, transmits loads and maintains the crushing chamber position.
Replacement Frequency	Low to moderate wear exposure; assess replacement or repair for worn support surfaces, deformation, cracks or loose liners.

Materials and Mechanical Properties

Item	Details
Material Options	High-strength cast steel, forged steel or quenched and tempered alloy steel, as specified in the OEM drawing
Typical Properties and Acceptance Criteria	Carries circumferential and axial loads from the concave segments, requiring adequate yield strength, core toughness, stiffness and dimensional stability. Check casting or forging integrity, flatness, roundness, support contact, bolt holes, locating surfaces and cracks. Wear or deformation can compromise the liner chamber profile.
Principal Failure Mechanism	Sliding or three-body abrasion, localized 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.
