How soccer ball is made - material, making, history, used ...

They are Ball bearing-style pins and friction pins. Guide bushings are slightly bigger in inside diameter than the pins as they are precision-ground pins. Bushings are made of a special wear-resistant material known as aluminum-bronze and the guide pins are made of hardenable steel. As the aluminum-bronze contains graphite, so it reduces friction.

Ball Milling - an overview | ScienceDirect Topics

Ball milling is another technique which was reported very recently for the production of NFC. In this method, a cellulose suspension is placed in a hollow cylindrical container, partially filled with balls (e.g., ceramic, zirconia, or metal). While the container rotates, cellulose is disintegrated by the high energy collision between the balls.
