Here’s a summary of the solutions to common plastic crusher problems：
1.Startup difficulties/not starting
Symptoms:
No response when pressing the start button.
Abnormal noise during startup.
The motor is on but not spinning.
Frequent overload protection trips.
Solutions:
Check the circuit: Inspect power lines, contactors, and relays for any issues.
Voltage detection: Ensure voltage is within the allowed range to avoid low or high voltage.
Motor check: Test for short-circuits or broken windings in the motor.
Overload protection: Adjust overload protection settings to prevent unnecessary trips.
Manual check: Manually rotate the main axis to check for mechanical obstructions.
Bearing inspection and maintenance: Check for seized bearings, lubricate or replace as necessary.
2.Abnormal noise and vibration
Symptoms:
Metal clanking sounds.
Persistent vibration.
Periodic abnormal sounds.
Whining from bearings.
Solutions:
Check bearings: Inspect and replace worn bearings, ensuring proper lubrication.
Blade adjustment: Check blades for wear or looseness, adjust or replace as needed.
Rotor balancing: Check the balance of the rotor to ensure stable operation.
Tighten connections: Secure all loose bolts and connections to avoid vibration.
Belt check: Check belt tension and wear, ensure appropriate tension.
3.Poor crushing effects
Symptoms:
Uneven product size.
Oversized particles in the final product.
Decreased production output.
Incomplete crushing.
Solutions:
Blade maintenance: Replace or sharpen blades to ensure sharpness.
Gap adjustment: Precisely adjust blade gap, recommended gap is 0.1-0.3mm.
Screen cleaning: Inspect and clean screens for damage or blockages.
Feed optimization: Optimize feed speed and method, ensure even feeding.
Installation angle: Check the installation angle of blades for optimal crushing.
4.Overheating issues
Symptoms:
High machine body temperature.
High bearing temperature.
Severe motor heating.
Poor cooling system performance.
Solutions:
Clean cooling systems: Regularly clean cooling systems for efficient heat dissipation.
Fan check: Check fan operation, ensure proper function.
Load control: Adjust feed rate to prevent continuous full-load operation.
Lubrication check: Ensure adequate lubrication of bearings to reduce friction.
Environmental factors: Monitor and manage the ambient temperature of the working environment.
5.Blockages
Symptoms:
Blocked feed or discharge openings.
Screen blockages.
Crushing cavity blocked.
Solutions:
Feeding procedure: Establish a suitable feeding procedure, avoid overloading.
Preventive devices: Install anti-blocking devices to reduce blockages.
Regular cleaning: Regularly clean screens and crushing cavities for smooth operation.
Moisture content control: Manage material moisture content to prevent blockages.
Screen design: Optimize screen hole design for various materials.
6.Preventive maintenance recommendations
Develop a regular inspection plan.
Record operating parameters, assist in analyzing the causes of failures.
Establish a spare parts management system for timely replacement.
Regularly replace wearable parts to reduce failure rates.
Train operators to enhance skills and safety awareness.
Keep a failure record to summarize experiences and lessons learned.
