Abstract: A rotary powder compression molding apparatus is disclosed, which includes a rotary disk. The rotary disk has a mortar mounting portion, an upper pestle guide portion arranged above the mortar mounting portion, and a lower pestle guide portion arranged below the mortar mounting portion. An annular vertical wall, extending upward, is arranged on the periphery of the lower pestle guide portion, and a recessed powder trap portion is formed inside the vertical wall. Powder leaking from mortars is moved outwardly due to a centrifugal force, and is trapped by the powder trap portion.
