摘要：PURPOSE:To obtain molded products having uniform weight by executing uniform packing of a powdery material in a mortar in a case of overflowing excess amt. of the powdery material packed in the mortar out of the mortar while controlling the overflow and fluidization of the powdery material. CONSTITUTION:When a mortar 1 enters a powder compression molding section C, an upper pestle 2 is guided by an upper track means 5 and dropped and inserted into a packing chamber 14 for the mortar 1 through an upper opening 12. Then, a fixed load is applied to the upper pestle 2 and a lower pestle 3 by an upper and lower compression roller 7, 7 to execute compression molding of the powdery material P contained in a packing chamber 14 and a compression molded product Q is obtd. Thereafter, the upper pestle 2 is lifted and separated from the mortar 1, and, on one hand, the lower pestle 3 is also lifted and the compression molded product Q is pushed out of the packing chamber 14. The pushed-out product Q is transferred by a discharging plate 23 to a discharging port E.
