Abstract (en)
[origin: EP4094837A1] The present invention provides a ball mill device, including: a driving device to generate a driving force; a grinding vessel in which a space for accommodating an object to be pulverized ("object") therein is present; a first rotary body having a first pulley, which is provided to rotate the grinding vessel about a first central axis; a second rotary body having a second pulley, which is provided to rotate the grinding vessel about a second central axis - wherein the second central axis is arranged to intersect with the first central axis -; and an auxiliary pulley for changing a rotational direction so that a rotational force about the first or second central axis acts on the second or first central axis by a belt when the grinding vessel rotates about the first or second central axis.
