24 AGGREGATES MANAGER / September 2017 EQUIPMENT MANAGEMENT confirm the motor direction of rotation. Where mechanical exciters are used, check oil levels at recommended intervals. Once a year, check the oil for contamina- tion, as annual checks can reveal increas- ing wear. As with the vibratory motors, confirm counterweight settings and in- serts for consistency. Effluent treatment — Thickeners typ- ically require little maintenance, but the large planetary gearboxes and the asso- ciated hydraulic power units do require routine attention. Presses are really a story for another day. Remote condition monitoring is gaining more attention. Measuring power-draw, heat, vibration, pressure, and using belt scales can provide im- portant insights into plant operation and needed maintenance. Subtle vibrations can prelude noise, which is when most operators will react (too late). Most impor- tantly, in some circumstances, it can also prevent serious accidents. As a final word, remember noth- ing will make up for inappropriate (often cheapest) selection of equipment. Equipment that is too small, over-rated, and thus overstressed will always have compromised life no matter how good the maintenance. AM Worn apex leads to misplaced fines in the underflow. Complex seals require careful maintenance, but provide longer service.
