Essential Daily Maintenance for Your Plastic Pulverizer: Extend Its Life

Time:2025-07-10

Why Daily Plastic Grinder Maintenance Matters

Plastic grinders inevitably experience wear and performance decline during prolonged, high-intensity operation. Statistics show that grinders receiving regular maintenance last 3-5 years longer on average and suffer over 60% fewer breakdowns than unmaintained units.

II. Essential Daily Maintenance Checks

1. Pre-Startup Checks:

  • Inspect all bolts for tightness, especially grinding disc bolts.

  • Verify proper belt/coupling tension.

  • Check power cables for damage and ensure secure grounding.

2. During Operation Monitoring:

  • Listen for abnormal noises or vibrations.

  • Monitor motor temperature (keep below 65°C).

  • Watch ammeter for unusual fluctuations (may indicate internal blockage).

3. Post-Shutdown Cleaning:

  • Thoroughly clean residual plastic from the grinding chamber.

  • Clean screens to prevent clogging.

  • Remove dust from motor cooling fins using compressed air.

Regular maintenance cycle for key components

 

Component Name Maintenance Tasks Recommended Interval
Cutting Tools/Grinding Discs Inspect wear condition; sharpen or replace if necessary Every 200-300 hours
Bearings Lubricate with high-temperature grease Every 500 hours
Belts Check tension and wear condition Weekly
Screens Check for damage and clogging Per shift
Electrical System Inspect terminal connections and contactors Monthly

Common fault warning signals and processing methods

1. Abnormal noise:

Metal collision sound: It is possible that the tool is loose or foreign objects have entered, and the machine should be stopped immediately for inspection

Dull friction sound: Bearings may lack oil or be damaged

2. Decreased production:

Check if the screen mesh is clogged

Confirm if the tool is excessively worn

Check if the feeding speed is uniform

3. Excessive powder temperature:

Reduce the feeding speed

Check if the cooling system is working properly

Confirm if the tool clearance is appropriate
