A ball button feeder is a type of feeder that is used to feed small, spherical balls or beads into a process or machine. These feeders typically consist of a hopper or tray that holds the balls, and a mechanism that is used to dispense the balls one at a time.

Ball button feeders are commonly used in a variety of industries, including manufacturing, automotive, and aerospace. They are used in processes such as grinding, milling, and finishing, where small balls are used as abrasives or media.

There are several different types of ball button feeders, including gravity feeders, vibratory feeders, and centrifugal feeders. Gravity feeders use the force of gravity to dispense the balls, while vibratory feeders use a vibrating tray to move the balls. Centrifugal feeders use a spinning disc to fling the balls out of the feeder.

Ball button feeders are designed to handle a wide range of ball sizes, and can be customized to meet the specific needs of the application. They are known for their accuracy and reliability, and are used in many different types of machines and processes.
