Discharge-Setting Wedges

Name: Discharge-Setting Wedges
Brand: ANRANST

Moves as a pair to adjust and lock the closed-side setting (CSS).

Discharge-Setting Wedges (CSS Adjustment Wedge)— Jaw Crushers Wear part, position 11.

Installation and Function

Installation Position	In the adjustment mechanism behind the toggle plate, positions 11 and 12 in the numbered diagram.
Main Function	Moves as a pair to adjust and lock the closed-side setting (CSS).
Replacement Frequency	Low; uneven loading, inadequate lubrication or incorrect locking accelerates wear.

Materials and Mechanical Properties

Item	Details
Material Options	Quenched and tempered alloy steels such as 40Cr and 42CrMo, or OEM-specified cast steel
Typical Properties and Acceptance Criteria	Requires high compressive strength, core toughness, mating wedge contact and fretting resistance. Verify wedge angle, matched height, guide surfaces, adjustment threads or hydraulic interfaces. Hardness must not compromise impact or crack resistance.
Principal Failure Mechanism	Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism

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.
