Ball Milling FAQ

Sep 02, 2009Page 1 of 16 - Ball Milling FAQ - posted in Newbie Questions: This is a commonly asked subject, so I thought I would provide an easily accessible central location. This is a simplified guide, and is in no mean meant to be all-inclusive. Do I need a ball mill? In a technical sense, you do not NEED a ball mill, but it's hard to progress too far in the hobby without one.

Grinding Equipment

In the ball mill, the energy for grinding is derived from the acceleration of the balls in a gravitational field. Under normal conditions, the latter limits the speed at which a mill of a given diameter can be run and therefore limits the rate at which energy can be applied to the process. Long milling times are characteristic of the ball mill.
