Abstract The invention relates to a roller mill comprising two rollers (1, 1'), which are arranged in parallel and which are pressed against one another and which rotate in opposite directions, wherein one of said rollers (1') is displaceable orthogonally with respect to the axial direction of said roller (1'), and two drives, which drives are assigned to in each case one the two rollers (1, 1') and each have an electric motor (2, 2'), a master electric motor (2) of the electric motors defines a target value (61) for the rotational speed or the torque as a reference, and a reference of a follower electric motor (2') of the electric motors comprises the actual value (62) of the torque or the rotational speed of the master electric motor (2) multiplied by a load sub-factor (64). L'invention concerne un broyeur à cylindres comprenant : deux cylindres (1, 1') parallèles l'un à l'autre, pressés l'un contre l'autre et tournant en sens inverse, un des cylindres (1') étant mobile perpendiculairement à la direction axiale de ce cylindre (1') ; deux entraînements, lesquels sont associés à chacun des deux cylindres (1, 1') et lesquels comprennent chacun un moteur électrique (2, 2'), un moteur électrique maître (2) parmi les moteurs électriques prédéfinissant une valeur théorique (61) pour la vitesse ou le couple en tant que référence, et une référence d'un moteur électrique suiveur (2') parmi les moteurs électriques englobant la valeur réelle (62) du couple ou de la vitesse du moteur électrique maître (2) multipliée par un facteur partiel de charge (64).
