هڪ پروفيشنل Crushing And Screening Equipment Assembly Plant Inspection هڪ منظم آهي, thirdparty verification service conducted at the OEM’s or integrator’s facility prior to equipment shipment. This process validates that the assembly of primary crushers, secondary cones, اسڪرين, پهچائيندڙ, and associated structures meets all engineering drawings, torque specifications, and alignment tolerances.
آپريشنل ڪم فلو:
1. PreInspection Documentation Review: Analysis of assembly drawings, ويلڊنگ جي طريقيڪار, component certifications (gearboxes, بيئرنگ), and factory acceptance test (FAT) پروٽوڪول.
2. Physical Dimensional & Mechanical Verification: Laser alignment of crusher drives and screen shafts; verification of bolt torques; inspection of weld quality on frames and chutes; confirmation of proper lubrication system assembly.
3. PreDelivery Functional Testing (جيڪڏهن قابل اطلاق): Witnessing noload runin of motors, gearboxes, and screen mechanisms; verifying control panel functionality and sensor calibration.
4. Final Compliance & Documentation Handover: Issuance of a detailed inspection report with photographic evidence, nonconformance notices (جيڪڏهن ڪو), and a certified dossier of asbuilt records for your plant files.
ايپليڪيشن جو دائرو & حدون: This service applies to new equipment assemblies and major rebuilds. It is a validation of workmanship and assembly against spec; it does not replace the OEM’s warranty for inherent component design or material defects.
