粒状にする方法が一般的である。(Prior Art) In general, furnace molten material is cooled and solidified into flakes, sublimated crystals, lumps, powders, granules, etc., and each is handled in its own unique state. Among these, granulated products have advantages such as convenience in packaging and handling during use, and uniform reaction. Conventionally, granulation is performed by cooling and solidifying on a rotating disk or cylinder to form flakes, or cooling and solidifying into lumps, and then crushing them to form granules.

となるなどの欠点がある。 However, handling corrosive substances and sublimable substances using these general methods requires relatively complicated equipment and operations, which tends to cause difficulties. Furthermore, some sublimable substances may partially sublimate and powdered substances adhere to the surface of the finished granular product, lowering the product value or causing caking after packaging. There are drawbacks.

In Publication No. 6672, an exhaust fan is provided at the top, a material injection nozzle is provided in the conical part near the top, and an appropriate number of cooling water injection nozzles are provided on the side wall of the lower half of the tower. An apparatus has been proposed in which an air inlet is provided at the bottom of the machine, and the rising air introduced through the air inlet is cooled, and the melt is dropped into the cooling atmosphere for granulation.

きないという欠点がある。(Problems to be solved by the invention) The above method is suitable for granulating non-sublimable substances, but in order to granulate sublimable substances, the sublimed substances adhere to the raw material injection nozzle. It has the disadvantage that it solidifies and blocks the nozzle, and furthermore, because it cools slowly, it causes spherical breakage and deformation, and the surface sublimates and cannot have a metallic luster.

ーキングしないものである。 The inventor of the present invention has made the following new findings as a result of various studies in order to solve the above-mentioned difficulties regarding the spheroidization of sublimable substances such as iodine. That is, a sublimable substance is melted and continuously blown out from a nozzle to form droplets, and as the droplets disperse and fall, an insoluble liquid having a boiling point lower than the melting point of the substance is sprayed. We discovered a method to cool and solidify droplets. and,
According to such a method, corrosive substances and sublimable substances can be smoothly and advantageously spheroidized without requiring complicated equipment or operations. Furthermore, the resulting spheroidized product is a new type of spherical product that has a smooth surface with a metallic luster, has no partially sublimed powdered substance attached to the particle surface, and does not cause caking even after packaging. It is something.
