Wet granulation method for cobalt powder

The invention provides a wet granulation method for cobalt powder. The method comprises a step of mixing: spraying a molten granulating agent onto the cobalt powder to uniformly mix the cobalt powder with the granulating agent, and then spraying a solvent to uniformly mix with the cobalt powder to obtain a mixture. The granulation method disclosed by the invention has the advantages that the process is simple, the granulating agent is uniformly mixed, and the sphericity degree of prepared pellets is high. 本发明提供钴粉湿法制粒方法,包括混合步骤，先将熔融的制粒剂喷洒到钴粉上，使钴粉与制粒剂均匀混合，然后再喷洒溶剂与钴粉混合均匀，得到混合料。本发明的制粒方法具有工艺简单、制粒剂混合均匀和制得的丸粒球形度高的优点。
