Abstract
The disclosure describes a driving device for a mill including a gear ring, suitable for being fastened to a grinding chamber, a first reduction transmission suitable for transmitting a rotation from a first motor to the gear ring, the reduction transmission comprising a case, an output module including an output pinion and an output shaft defining an output axis. The gear ring has helical teeth, the output pinion has helical teeth, the or each output module can be inserted in a single piece into the associated case in an insertion direction or removed in a single piece from that associated case in a removal direction. The driving device includes a disconnectable connecting element suitable for rotatably connecting the output shaft to a transmission element and allowing, in a disconnected state, a rotation of the output pinion around the output axis upon removal of the output module outside the case or during insertion of the output module into the case.
