Why is the recovery system of electrostatic powder spraying inefficient?

Why is the recovery system of electrostatic powder spraying inefficient?
The inefficiency of the recovery system in electrostatic powder spraying arises from several key factors:

1. **Overspray and Losses** – Not all powder adheres to the workpiece; some become overspray, which may not be fully captured.
2. **Inefficient Cyclone Separators** – Many recovery systems use cyclones to separate reusable powder, but fine particles can escape, reducing efficiency.
3. **Degradation of Recovered Powder** – Recycled powder may lose quality due to contamination, particle size reduction, or moisture absorption, limiting its reuse.
4. **Cross-Contamination Risks** – Changing colors or powder types can cause contamination, making the recovery process less effective.
5. **Airflow Issues** – Poorly designed air circulation or clogged filters can hinder powder collection and lead to loss.
6. **Maintenance Challenges** – Lack of proper cleaning and filter replacement reduces system efficiency over time.
7. **Energy Consumption** – Recovery systems require significant airflow and separation power, and inefficiencies in these processes increase operating costs.
