Have you ever noticed the bouncing balls jumping up and down on the sieve mesh when the vibrating screen works? What's special role of bouncing ball? Today we will take a brief look.
These bouncing balls are an essential part of vibrating screening machines. Its role is beating the sieve mesh up and down to avoid adhesion material blocking the sieve mesh, otherwise, the adhesion material will affect the screening efficiency and accuracy.
Bouncing balls are generally divided into different diameters: φ10, φ15, φ20, φ25, φ28, φ30, φ40, φ50, φ60 and so on, commonly used ones are φ25 and φ28 , while φ40, φ50and φ60 are mainly used for mining vibrating screen.

According to the construction material, bouncing ball can be classified into several types: rubber ball, silicone ball, PTFE ball, according to different construction materials of bouncing balls, the application and function are also different.
Natural rubber bouncing ball is suitable for general material screening process;
Silicone bouncing ball has good elasticity., mainly used for food, medicine and other materials screening;
PTFE bouncing ball can be soaked in the oil, mainly applied to oily liquid materials screening.

The bouncing balls should be selected based on different material properties to meet customer requirements in different conditions. Though bouncing ball is a small accessory, it is the key to solve the screening problem.
