<p>The invention relates to a method of operating a mill of the kind having a mill body provided with end-walls, and including a mill burden discharge trunnion arranged externally of one end-wall. The mill is rotated about a generally horizontal rotational axle which is common to the mill body and the discharge trunnion. The inventive method is characterized by resting the mill body on at least two supports so arranged as to support the whole of the mill, and by rotating the mill body, while supported by these supports, by means of a hydraulic motor which is connected mechanically to the discharge trunnion and the rotational axle of which is common to the rotational axle of the discharge trunnion and the mill. The invention also relates to a mill which includes two end-walls which extend generally perpendicular to their respective rotational axes and through which mill burden is introduced into and discharged from the mill respectively, a cylindrical mill casing which is supported between the end-walls and connected mechanically thereto, and a mill burden discharge trunnion which is connected to the discharge end-wall and faces outwardly therefrom. The mill is characterized in that each end-wall includes a support ring having an outwardly-facing contact surface and being generally parallel with the rotational axle; in that the discharge end-wall and the discharge trunnion are intended to transmit requisite torque from the discharge trunnion; and in that the discharge trunnion is intended for connection to the hydraulic motor by means of which the mill is rotated. <IMAGE></p> |
