As we all know, bouncing ball plays an important role for rotary vibrating screen, however, bouncing balls can be divided into different types, here PK Machinery will introduce in details:
Natural rubber bouncing ball: suitable for general material screening process;

Silica gel bouncing ball: silica gel has the advantages of good elasticity and wear-resisting ,which is not easy to fall off, mainly applied to food, medicine and other material screening.
