jul 05, 2020 several types of ball mills exist. they differ to an extent in their operating principle. they also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
may 27, 2006 the ball temperature remains below 100 in a spex 8000 shaker mill and it is cooler when flat-ended rather than round-ended vial is used, although the milling intensity, as measured by the mechanical dose rate, follows the opposite trend. temperatures over 200 are typical in planetary mills operating at similar milling intensities.
By using the planetary ball mill, we can produce high mechanical activation. So the milling time is relatively shorter compared with conventional milling process and the energy density is 100 to 1,000 times higher compared to conventional mill and productivity can be significantly enhanced compared to conventional mill in level about 1,000 percent.
