PURPOSE: A cooling system for planetary ball mill is provided to stably operate a planetary ball mill by improving the durability of a planetary ball mill. CONSTITUTION: Refrigerant frozen with a refrigerant refrigerator(100) flows in a refrigerant inlet line(200). A cooling jacket part(500) is respectively formed in the external periphery of a grinding box(10). Refrigerant passing the refrigerant inlet line flows into the cooling jacket part. A revolving axis flow path(600) is formed in the inside axial of a revolving axis part(20). The revolving axis flow path is communicated with the flow path(512) of the cooling jacket part. The refrigerant passing the revolving axis flow path is exhausted to the refrigerant refrigerator in a refrigerant discharge line(800).
