Design of Parts for Milling: What follows is a list of recommended design practices for milled parts. The list is not exhaustive, but is what our staff has found to be most useful. Design milled areas so that the end mill required is limited to 3:1 in length to diameter ratio. As shown in the figure below, longer end mills are prone to chatter.

ball mill length and diameter ratio. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 0.5 to 3.5.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and .
