A review of the available literature on the development of tube mill drives is presented in this paper. This presentation includes the motor selection, a mill drive analysis, a failure analysis, the lubrication, the vibration measurement and the finite element analysis, covering strain and fatigue design and a brief write-up on materials and inspection.
42 CEMENT INTERNATIONAL 4 2/2016 4 VOL. 14 Rising demand from the cement industry for ever greater mill capacities is having implications for the drive systems that have been used up to now.
Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption ).

Although a complete system analysis is beyond the scope of this paper, when conducting a root cause failure analysis, it is important to recognize that the motor is only one component of a system. Many factors affecting the system will also affect the motor and may contribute to the motor failure and vice versa. Fig. 1 shows a typical system.
