How To Determine If A Cable Separating Machine Needs Maintenance?

I. Operational Abnormalities: Equipment Issues "Distress Signals"

Increased Noise or Abnormal Sounds: Such as metallic friction sounds or whistling, which may indicate bearing damage or loose cutters.

Increased Vibration: Noticeable overall equipment shaking, possibly due to dynamic imbalance or loose foundation bolts.

Motor Overload Alarm or Large Current Fluctuations: Indicates increased internal resistance, suggesting blockage or transmission component failure.

II. Decreased Processing Performance: Efficiency Noticeably Reduced

Uneven Output: Increased plastic inclusions in copper granules, leading to higher copper content in the plastics and separation purity below 98%.

Reduced Processing Capacity: Under the same feeding conditions, output per unit time decreases by more than 15%.

Uneven Particle Size: Significant differences in material size after crushing, with an increase in fine powder or long, strip-shaped fragments, affecting subsequent sorting.

III. Critical Wear of Key Components

Based on measured data and industry standards, the following components must be maintained when they reach their usage limits:

Wear of Moving Cutters ≥ 0.5mm: Approximately 0.17mm of wear occurs for every 80 tons of cable processed. Exceeding this limit cumulatively will increase the uneven crushing rate to 31%.

Screen Usage Exceeds 1200 Working Hours: Aging and deformation of the polyurethane screen plate increases the copper particle entrainment rate by 2.8 times.

Severe Dust Accumulation in Air Ducts: Electrostatic adsorption causes plastic backflow, affecting air separation efficiency. High-pressure cleaning is required monthly.

IV. Maintenance Cycle Reminder: Triggered by Time or Workload

Even without obvious abnormalities, a three-tiered maintenance system should be followed: "Clean every shift + Lubricate every 200 hours + Inspect cutters every 600 hours." Preventative maintenance can increase the equipment's annual effective operating time to 3670 hours and reduce unit energy consumption by 11.4%.
