Vibratory Screen Breakdown Repairs & Electrical Fault Finding

Exciter motor cable fatigue, unbalanced dual-motor phase mismatches, and dead-weight starter trips will halt aggregate and mineral sizing plants. Lectro Power Systems installs flexible vibration-rated cabling, rebuilds terminal connections, and tunes dual-motor synchronization across Western Australia.
Symptoms We Resolve

Common Vibratory Screen Faults We Diagnose & Fix

  • Vibration-Induced Terminal Stud Shearing

    Repairing fractured terminal boxes, sheared terminal lugs, and arced lead connections.
  • Trailing Cable Core Fatigue Breaks

    Replacing standard cabling with extra-flexible, polyurethane-sheathed screening cables designed for continuous flexing.
  • Dual Unbalance Motor Phase Mismatches

    Diagnosing rotational direction errors and current imbalances causing irregular screening motion.
  • Direct-On-Line Starter & Overload Trips

    Investigating eccentric weight starting inertia, single-phasing, and bearing drag overcurrents.
  • Exciter Bearing Temperature Sensor Trips

    Wiring and calibrating RTD temperature sensors and thermistors in exciter bearing housings.
  • Screen Blinding & Blockage Sensor Faults

    Troubleshooting proximity sensors, tilt switches, and automated spray-bar solenoid valves.
