The screen cleaning ball is an indispensable small part of the vibro sifter. Its function is to hit the screen by cyclically hopping back and forth between the rotary vibrating screen and the pallet, imitating the manual tapping of the screen surface, so that the material adhering to the screen surface can be separated from the screen. Avoid blocking the screen from affecting the screening output and accuracy.

Types Of Screen Cleaning Balls
When choosing a bouncing ball, we should fully consider its material to meet performance needs under different conditions.
1. Silicone Gel Ball
Silicone bouncing balls have good elasticity and wear resistance and are not easy to fall. It is widely used in the screening of food, medicine, and other materials.
2. Rubber Bouncing Ball
Natural rubber bouncing balls are suitable for general material screening processes.
3. PTFE Bouncing Ball
PTFE bouncing balls can be soaked in oil and are specially used for screening oily liquid materials.
Function Of The Screen Cleaning Balls
The bouncing ball impacts the screen mesh by moving up and down in the vibrating screen machine, thereby preventing or reducing clogging. The screen mesh of the vibratory screen is an important component of the vibrating screen. There are bouncing balls cleverly installed between the screen mesh and the mother mesh. These bouncing balls can weaken the adhesion of materials on the mesh through their unique impact effect and achieve a clean screen. The function of the net is to improve the efficiency of materials passing through the net.
Custom Screen Cleaning Balls
To provide the most suitable screen cleaning balls for your vibrating screen, please provide the following customised parameters:
- Screen model/size: Vibrating screen brand and screen frame inner diameter
- Screen mesh size: Screen mesh count or millimeter size
- Material characteristics: Material name, viscosity, temperature
- Operating conditions: Operating temperature (maximum value), anti-static/food grade certification requirements (such as FDA), wear resistance grade requirements
- Existing issues: Core pain points to be addressed
