A heavy-duty transmission for the drive of a bowl-mill roller crushers is disclosed, comprising a bevel gear stage ( 6; 7 ), a horizontal input drive shaft ( 5 ) and a vertical output drive shaft ( 8 ) and a multi stage planetary gearbox arrangement which is connected to the vertical output drive shaft ( 8 ) by a sun pinion ( 9 ) and is connectable to the grinding bowl of the roller mill by an output flange ( 3 ). Planetary wheels ( 10 ) engageable into the sun pinion ( 9 ) are placed on a first plane on a planetary wheel support ( 14 ) which is connected to the output flange ( 3 ). On a second plane, other planetary wheels ( 15 ) are arranged in such a way than the axes of rotation thereof are connected to a gear housing ( 2 ) and which are engageable into a ring gear ( 20 ) connected to the support of the planetary wheels ( 14 ) and are engaged into the sun pinion ( 19 ) of an intermediate gear wheel ( 17 ), which is also provided with a ring wheel ( 18 ) which gearing from outside into the planetary wheels ( 10 ) on the first plane.
