    And small grain size of the natural media types limit the size of media, and therefore size of feed that can be milled. For example, sand media typically breaks down to its natural grain size when exposed to the high intensity milling environment. Generally sands have grain sizes finer than 5 mm. This limits the feed size that the mill can treat.
