Abstract
A planetary ball milling system comprises a planetary ball mill including a central axis, a hub, and a plurality of milling pots surrounding the central axis. In some examples, the milling pots are configured to be transitioned between horizontal and vertical positions during operation of the planetary ball mill. The planetary ball milling system can further include vibrating impacting rods for vibrating and striking the milling pots, and nozzles for dispersing a cooling agent onto a surface of the milling pots.
Claims19
A planetary ball milling system comprising:
- a planetary ball mill including:
- a central axis;
- a hub arranged orthogonal to the central axis and configured to be rotated around the central axis during operation of the planetary ball mill;
- a plurality of milling pots disposed around the central axis and connected to the hub, each of the plurality of milling pots having a longitudinal center line, wherein each of the plurality of milling pots is configured to be concurrently rotated around the central axis and a respective longitudinal center line during operation of the planetary ball mill, and wherein each of the plurality of milling pots is configured to be transitioned from a vertical orientation to a horizontal orientation during operation of the planetary ball mill;
- wherein the longitudinal center line of each of the plurality of milling pots is parallel to the central axis and orthogonal to the hub when in the vertical orientation, and
- wherein the longitudinal center line of each of the plurality of milling pots is orthogonal to the central axis and parallel to the hub when in the horizontal orientation;
- a plurality of vibrating impacting rods disposed above the milling pots and configured to vibrate and strike the plurality of milling pots while the plurality of milling pots are in the horizontal orientation;
- and
- a plurality of nozzles disposed above the plurality of milling pots and configured to disperse a cooling agent onto a surface of the plurality of milling pots while the plurality of milling pots are rotating in the horizontal orientation.
