Edge mill
An edge mill is a mill used for crushing or grinding in which stones roll around on their edges on a level circular bed. They were developed in China in the third century and are still used today in remote villages around the world. When the millstones were replaced with iron or steel disks in the 19th century, they were known as a Chilean mill.[1]
