Abstract:
A planetary ball mill apparatus for producing nanometer-scaled powders, comprising:(a) a main rotary wheel comprising supporting members;(b) a plurality of mill pots which are revolvable by receiving a rotational force from said main rotary wheel, said pots being disposed around said main rotary wheel with substantially equal distance between one mill pot and another, each said mill pot comprising a tiltable pivotal shaft having rotary coupling means so that each said pot can also rotate about its own axis, and each said pivotal shaft having one end being supportably connected to one of said supporting members of the main rotary wheel;(c) motor means in drive relation to said main rotary wheel for providing rotational forces thereto; and(d) a non-revolvable counter-acting supporting ring disposed coaxially with said main rotary wheel and in the close, working proximity to said mill pots with each said tiltable pivotal shaft being capable of tilting toward said supporting ring permitting each said mill pot to periodically contact therewith, thereby inducing a planetary motion of said mill pot about its own axis.
