In the design of bearing systems whenever you think you have a good design, invert it, think of using a com-pletely different type of bearing or mounting, and com-pare it to what you originally considered.Why did some civilizations discover bearings and others did not those with bearings moved farther faster, and history has yet to stop.

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.
