FIELD: mechanical engineering; mills. SUBSTANCE: rattler has horizontal drum installed for rotation of which rims and ribs are installed from outer side on at least of drum. Said rims and ribs are used to equalize temperature of drum and ambient temperature depending on characteristics of processed materials. Shell can be installed over rims and/or ribs. Rims and/or can be installed at angle to axis of rotation of proposed rattler. EFFECT: improved efficiency of grinding, increased strength of drum. 3 cl, 4 dwg
