All constant speed motors with an output of more than 200 kW are connected to the medium-voltage system of 6.3 kV. Bigger motors, such as the motors for the raw and cement mill, are slip-ring motors and are equipped with over temperature sensors in the stator windings and bearings, vibration detectors and space heaters.

The base rigidity of the concrete structures has to be strengthened. Vibration readings taken at mill HP pump running at various RPM, The vibration level was less and almost 8mm/sec to 9mm/sec when the pump was running at 900 rpm, so it is advisable to run the pump at 900 rpm to have minimum vibration in the SAG Mill. Conclusion:

Vibration monitoring in the cement industry When sensors are to be installed on a crusher, screen, conveyor pulley or drive, for example, a side-entry model may be preferred over a top-entry component, so that debris cannot damage the sensor. In high temperature areas, an appropriately protected sensor should be used. Specify and install
