The present invention relates to a stirring mill to prevent a device and liquid material therein from overheating when the material is stirred or a grain is atomized by forming a cooling jacket on a stirring container used to stir the material, thereby preventing damage to the device and also providing high-quality product material. In addition, the objective of the stirring mill is to allow the material to circulate smoothly by properly positioning a separate impeller. The present invention provides the stirring mill used to stir or atomize the liquid material contained inside a material container (33). The stirring mill comprises: the cylindrical stirring container (34) which is hung by suspenders (35) coupled with an upper frame (32) and includes an inlet port (36) for letting the material in and a screen (42) for venting the material; and a rotor (38) coupled with a rotary shaft (39) which is coupled with the upper frame (32) and extended downward in order to rotate inside the stirring container (34), wherein the screen (42) is formed on either the external side, the upper side, or the lower side of the stirring container (34) and the cooling jackets (50, 51) are formed on the other sides.
