It is believed that milling machines date back to the 1700s although it is unclear exactly when they were first invented or by whom they are very similar to lathes so the earliest models were most likely just variations on the typical lathe machine milling machines became a separate class of tools sometime between 1814 and 1818
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
