Choosing the Best Media Mill For Your Wet Grinding Appliion
· Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with to mm grinding media. By reducing the media diameter to to mm after 90 minutes, the target grind is achieved in only 150 minutes.

A New Milling 101: Milling Forces and Formulas
· Radial forces tend to push away the tool and account for 10 percent of the cutting forces. The tool's rake controls the degree of cutting forces and power consumption, the strength of the cutting edge, and the direction of chip flow. As a rake angle becomes more negative, cutting forces increase and edge strength improves.
