Vibrating Screen Bouncing Balls: Anti-Blinding & Cleaning Guide

In industrial screening operations, maintaining clear screen openings is crucial for efficiency. Vibrating screen bouncing balls, also known as screen cleaning balls or anti-blinding balls, are simple yet vital accessories designed to tackle screen clogging (blinding).

What Are Vibrating Screen Bouncing Balls?

These are small, spherical balls placed between the screen mesh and the support grid. As the vibrating screen operates, the balls continuously bounce and tap against the underside of the screen, dislodging lodged particles and preventing blockages.

Key Materials & Properties

Bouncing balls are made from durable, non-abrasive materials to clean effectively without damaging the screen.

Rubber: The most common type. Offers good durability, elasticity, and cost-effectiveness for general applications.

Silicone: Used for higher temperature resistance or more demanding chemical environments. Provides excellent flexibility.

Food-Grade/Urethane: Specialized materials for food, pharmaceutical, or high-wear applications where specific certifications or properties are needed.

Primary Functions & Benefits

The main function of these balls is screen cleaning and blinding prevention.

Prevents Blinding: They keep mesh openings clear by knocking out trapped particles, ensuring consistent screening accuracy and throughput.

Improves Efficiency: By maintaining an open screen area, they help maintain optimal material flow and classification efficiency.

Reduces Downtime: Minimizes the need for frequent manual screen cleaning or stoppages, boosting productivity.

Extends Screen Life: Proper cleaning reduces wear from aggressive manual cleaning methods.

Installation & Selection Tips

The balls are typically installed in a ball tray or ball deck mounted beneath the screen panels.

Size & Number: Ball size (commonly 20mm to 40mm) and quantity should be chosen based on screen mesh size and the specific material being screened. A proper coverage area under the screen is key.

Material Selection: Match the ball material to your application’s temperature, chemical exposure, and industry requirements.

Conclusion

Vibrating screen bouncing balls are a cost-effective and efficient solution for maintaining screen clarity. By understanding their materials and function, operators can select the right type to reduce blinding, enhance screening performance, and minimize maintenance downtime. For optimal results, ensure correct installation and periodic inspection for wear.
