Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly

Mill Pinion Replacement Oversight Global

Pinions typically see 10-20 X the number of cycles as the mill gears, despite being harder and designed for this load. Wear, Macropitting, and Fatigue Cracking are common failure modes that compromise pinions. Conducting regular stroboscopic inspections, stop action photographs, temperature monitoring, and vibration analysis is essential to catch these failure modes early and avoid unplanned downtime.

Cadia Girth Gear Failures

22/09/2014 The gears and pinions on the Cadia ball mill gears failed due to a design fault. We agree with [2] that a larger pinion may have avoided the gear scoring, however, the location of the damage can only be explained by thermal ratcheting resulting in differential expansion. The damage to both the loaded and unloaded flanks of the girth gear are consistent with the gears almost jamming.

The failure mode for each component has been determined. The effects of failure were then categorised as Local effect, Next effect and End effect. This categorisation helps in identifying the root cause(s) easily and applying severity rating accurately. The relationship between failure mode and root cause may not be always one to one. A single failure mode may have more than one root cause. A Risk Priority

Grinding Mill Foundations

23/09/2014 Another interesting foundation we studied is the Fimiston SAG mill foundation. The gears on the mill on this foundation were very difficult to align and the alignment and vibration of the system was worse when the mill was rotated in one direction rather than the other. We found that the direction of rotation would result in a change in the vibration levels at the pinion piers of up to 7 times depending

Unexpected mill stoppage In the event of an unscheduled or emergency shutdown, it is mandatory for the mill to be flushed out with water while it is inched. The percentage of solids in the mill should be monitored until they are at a safe level that prevents a locked charge during the next mill start. Incorrect starting procedure of

Drive Solutions for the Global Mining Industry

Application 1. Grinding Mill Systems Grinding mills are crucial to mineral processing operations. As lower quality ore bodies are tapped, the tonnage processed per ounce of salable material will increase. This degradation in ore quality requires more power in the mill circuit, meaning larger motors and drives. Synchronous, squirrel cage induction, and wound rotor motors may be a good choice depending

Timken Bearing Damage Analysis with Lubrication Reference

Failure to observe the following warnings could create a risk of serious injury. Tensile stresses can be very high in tightly fitted bearing components. Attempting to remove such components by cutting the cone (inner race) may result in a sudden shattering of the component causing fragments of metal to be forcefully expelled. Always use properly guarded presses of bearing pullers
