Common Problems and Solutions for Plastic Shredders
1 Shaft Jamming
Cause: Hard materials or overload operation.
Solution: Immediately shut down, reverse the shaft to remove the jammed material. If ineffective, manually clean.
2 Uneven Particle Size
Cause: Damaged or worn screen.
Solution: Inspect and replace the screen.
3 Abnormal Noise
Cause: Damaged bearings or unbalanced shaft.
Solution: Requires professional inspection.
4 Equipment Failure to Start
Cause: Power issues, unreset limit switches, motor overload, or transmission mechanism jam.
Solution: Check power lines, close the hopper locking nut, replace blown fuses, inspect motor windings.
5 Shredder Blockage
Cause: Excessive feeding speed, blocked discharge pipes, or severe tool wear.
Solution: Adjust feeding speed, clean conveying equipment, replace tools.
6 Bearing Overheating
Cause: Uneven bearing seat height, insufficient or excessive lubrication, prolonged overload operation.
Solution: Adjust bearing seat or motor position, add lubricant on time and in proper quantity, reduce load.
7 Abnormal Vibration
Cause: Loose foundation bolts, damaged shaft bearings, or internal hard objects jamming.
Solution: Tighten foundation bolts, replace bearings, clear internal hard objects.
8 Significantly Reduced Output
Cause: Screen blockage, uneven feeding.
Solution: Clean the screen, adjust feeding speed.
9 Tool Breakage or Wear
Cause: Low material fragmentation or inability to normally crush.
Solution: Check tool and shaft operation, replace or adjust gaps.
10 Shaft Rotation Noise
Cause: Loose shaft, worn elastic rings.
Solution: Stop the machine, tighten the pin shaft nut, replace elastic rings.
11 Internal Knocking Sound
Cause: Non-crushable objects entering the crushing chamber, loose tool fixing screws.
Solution: Clear non-crushable objects from the crushing chamber, tighten tool screws.
12 Electrical Faults
Cause: Power issues, blown fuses, damaged electrical components.
Solution: Check power lines, replace fuses, inspect and replace damaged electrical components.
13 Hydraulic Drive System Failure
Cause: Contaminated hydraulic oil, cooler failure, oil pump issues.
Solution: Replace hydraulic oil, inspect cooler, check oil pump.
14 Reduced Output
Cause: Screen hole blockage, uneven feeding.
Solution: Clear residual material from the screen, adjust feeding speed.
15 Belt Flipping
Cause: Worn belts.
Solution: Replace V-belts, adjust pulleys to the same plane.
16 Increased Particle Size
Cause: Excessive gap between moving and fixed blades.
Solution: Readjust the gap between moving and fixed blades.
17 Lubricating Grease Issues
Cause: Insufficient, excessive, or contaminated grease.
Solution: Clean bearings, add appropriate lubricating grease.
18 Unbalanced Main Shaft Rotor
Cause: Assembly issues, uneven foundation.
Solution: Adjust assembly, ensure a stable foundation.
19 Clogged Discharge Pipe of Induced Draft Fan
Cause: Blocked or obstructed pipes.
Solution: Clear the induced draft fan discharge pipes.
20 Tool and Spacer Scraping
Cause: Worn or loose tools.
Solution: Check tool wear, replace or sharpen promptly.
Safety Tips: When encountering failures, immediately shut down and cut off the power, and promptly contact professional maintenance personnel for inspection to avoid safety accidents caused by non-professional operations.
