Polyethylene (PE) pulverizers play a crucial role in plastic recycling and processing, converting plastic granules or scraps into fine powder used in applications like rotational molding, masterbatch production, coating materials, and more. However, like all mechanical equipment, PE pulverizers can face operational issues over time that impact efficiency, product quality, and production costs.
In this blog, we’ll discuss some of the most common issues that arise with PE pulverizers, their root causes, and practical solutions. We’ll also introduce Wuxi Songhu Xinrui Machinery Co., Ltd., a trusted Chinese manufacturer known for producing high-quality PE pulverizers and PVC crusher equipment, and explore how their advanced designs help prevent many of these problems.
1. Inconsistent Powder Fineness
Problem:
The output powder has an inconsistent or uneven mesh size, which can affect the quality of the final product.
Causes:
Worn or damaged grinding discs
Incorrect blade gap setting
Poor material feeding control
Solutions:
Regularly inspect and replace grinding discs.
Ensure correct blade gap calibration based on the desired mesh size.
Use automatic feeding systems to ensure uniform input flow.
Wuxi Songhu Xinrui’s pulverizers are equipped with precise adjustment mechanisms and durable grinding components to ensure consistent powder quality.
2. Overheating of the Machine
Problem:
The machine heats up excessively during operation, which can degrade the plastic and cause damage to internal components.
Causes:
Lack of cooling system or coolant circulation failure
Excessive motor load or overfeeding
Poor ventilation in the grinding chamber
Solutions:
Maintain and monitor water or air cooling systems.
Avoid overloading; ensure material feed is balanced.
Clean internal chambers to prevent airflow blockage.
Xinrui Machinery offers PE pulverizers with integrated cooling systems, ensuring continuous operation without overheating.
3. High Energy Consumption
Problem:
Energy usage spikes during operation, increasing operational costs.
Causes:
Worn blades or discs reducing grinding efficiency
Old or inefficient motors
Improper setup or misalignment of components
Solutions:
Use high-efficiency motors and check for proper alignment.
Replace worn parts promptly.
Invest in energy-optimized models with inverter systems.
Xinrui’s equipment is designed with energy-efficient technology to reduce power consumption while maximizing output.
4. Excessive Noise or Vibration
Problem:
The machine produces abnormal vibrations or noise, which can indicate mechanical imbalance or internal wear.
Causes:
Loose bolts or components
Imbalance in the grinding disc
Foreign objects inside the chamber
Solutions:
Tighten all fasteners and conduct regular maintenance.
Balance grinding discs during installation.
Use a metal detector or pre-screening process to remove contaminants.
Xinrui Machinery prioritizes vibration control and structural stability in its PE pulverizer design, enhancing both safety and durability.
5. Low Output or Blocked Discharge
Problem:
The pulverizer fails to produce the expected output or clogs frequently during operation.
Causes:
Blocked screens or worn discharge components
Feeding oversized materials
Improper airflow in pneumatic conveying systems
Solutions:
Clean or replace screens and check discharge openings.
Use proper pre-crushing equipment like PVC crushers before pulverization.
Ensure proper airflow control in the system.
As a full-solution provider, Wuxi Songhu Xinrui Machinery Co., Ltd. also manufactures PVC crushers and feeding conveyors to support the entire material preparation process.
