    • Finely-divided particulate bismuth oxide is produced by the steps of heating bismuth at 800.degree. C. or above in a first compartment of a sealed vessel divided into two compartments by a partition wall, the two compartments communicating with each other by a hole provided on the partition wall, feeding an inert gas such as nitrogen and argon into the first compartment so that the bismuth vapor formed by heating bismuth has a bismuth concentration of 0.1 to 0.5 g/liter, blowing air into the bismuth vapor introduced from the first compartment into the second compartment through the hole on the partition wall, permitting the air to mix with the bismuth vapor to form bismuth oxide and simultaneously cooling the thus formed bismuth oxide to 250.degree. to 300.degree. C., discharging by suction the bismuth oxide from the sealed vessel at a flow rate of 1 to 5 m/sec, and cooling the discharged bismuth oxide by supplying cooling air outside the sealed vessel.
    • 精细分散的颗粒状氧化铋是通过以下步骤制造的:通过在分隔壁分成两个隔室的密封容器的第一隔室中将800℃或更高的铋加热的步骤,两个隔室通过设置在 分隔壁将氮气和氩气等惰性气体供给到第一隔室,使得通过加热铋形成的铋蒸气的铋浓度为0.1〜0.5g / l,将空气吹入从第一隔室引入的铋蒸气 第二隔室通过分隔壁上的孔,允许空气与铋蒸气混合以形成氧化铋,同时将由此形成的氧化铋冷却至250℃至300℃,通过从密封的氧化铋中抽出氧化铋 容器,以1〜5m /秒的流速,通过在密封容器外部供给冷却空气来冷却排出的氧化铋。

    • A rear wall is detachably fitted at the rear of a body frame. A grinding wheel casing is also associated at the rear of the rear wall. A feeder wheel disposed on the front surface of the body frame and a rotatable grinding wheel provided within the grinding wheel casing are respectively rotated by a motor provided within the body frame. A cutter disposed opposite the feeder wheel cuts open a lid of a can rotated by the feeder wheel. The rotatable grinding wheel provided within the grinding wheel casing sharpens the edge of a knife inserted into the grinding wheel casing from a slit formed in a portion of the grinding wheel casing.
