Apron adjustment rod

Name: Apron adjustment rod
Brand: ANRANST

Transmits adjustment force and holds the impact apron at its set position.

Apron adjustment rod (Apron Adjustment Rod)— Impact Crusher Wear part, position 16.

Installation and Function

Installation Position	In the adjustment and retaining mechanism behind the impact apron; position 16 in location diagram A.
Main Function	Transmits adjustment force and holds the impact apron at its set position.
Replacement Frequency	Low to moderate wear exposure; replace for bending, thread scoring, fatigue cracks, nut failure or insufficient adjustment travel.

Materials and Mechanical Properties

Item	Details
Material Options	Quenched and tempered alloy steel of the 42CrMo/SAE 4140 type, or an OEM-specified high-strength rod material
Typical Properties and Acceptance Criteria	The rod carries cyclic tension and compression, impact and stress concentrations at the threads. Typical quenched and tempered hardness may be approximately 260–340 HB, but must be confirmed for the section size and load. Control forging or rolling quality, thread root radii, straightness, surface defects, MT inspection, nut contact and locking. Do not attempt to solve bending or fatigue by arbitrarily increasing hardness.
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.
