FIELD: machine building.
SUBSTANCE: invention relates to mills, in particular, to roller tray cement and coal mills, and can be used in heavy load cargo drive systems. A drive system (1) is equipped by a grinding pan (2) set so that to rotate around the vertical line (A), a casing (6) and a gearing system (4) resting against the casing (6). An electric motor (5) is installed above the gearing system (4) and is integrated in the casing (6). The electric motor (5) rests against the casing (6) and first of all against a supporting element (6c) of the casing. A rotor (7) can be connected to the gearing system (4) directly or via a clutch integrated in the rotor (7).
EFFECT: drive system (1) is characterised by small dimensions and high wear resistance and does not require frequent maintenance.
