FIELD: technological processes. ^ SUBSTANCE: invention refers to powder metallurgy, and namely to drum ball mills. Mill comprises drive and drum installed on it to fill with grinding bodies and liquid, and also at least one heat sensitive sensor pressed to drum and connected to drive of drum rotation through controller of rotation speed. Drum is filled with liquid of viscosity of not lower than 0.5ù10-3 Paùs. At the same time device is arranged with the possibility to reduce drum rotation speed while liquid temperature increases, and to increase speed of rotation while this temperature goes down. ^ EFFECT: increased efficiency of mill. ^ 1 dwg |
