Ignoring mechanical losses in this drive train, the power transmission at each stage, defined as torque x speed, is constant. The typical mechanical inching drive motor speed is around 1500 to 1800 RPM while the mill inching speed is in the order of to RPM. Thus, the gear reduction ratio between the inching drive motor and the mill is ...

wear to the mill liners and ball consumption, as explained by a concentrator's operation and maintenance supervisor in the US. Furthermore, the mill's direction of rotation can be simply changed with a switch, so that the wear on the liner is distributed equally at both sides. Reduced wear of the liners prolongs the mill maintenance intervals.

The Sydvaranger SAG mill. Originally, the mill was supported by five shoes on each side: one at the bottom 6 o'clock position and two on either sides of it. The stability of the bearing was questionable and as in the case of Chuquicamata, the mill was escaping sideways from its bearings. The St. Lawrence Cement mill

Coal mills consume a huge amount of station service electricity power of a coalfired power plant. Meanwhile, the operation of coal mills also has a large influence on boiler combustion. Among all the operating factors, the electricity current intensity of coal mills reflects the electricity power consumption as well as operating status of coal mills. If the electricity current intensity of ...
