• Crusher & Plant Monitoring
• Operate the primary gyratory crusher, feeders, conveyors, chutes, scalping screens, and dust suppression systems from the control room.
• Monitor equipment performance using SCADA/DCS systems.
• Adjust feed rates to ensure optimal crusher throughput and product size.
• Identify and respond to process upsets (blockages, overloads, low level, tramp metal alarms).

Safety & Compliance

• Follow mine site safety regulations, lock-out/tag-out (LOTO), confined space rules, and emergency procedures.
• Report safety concerns and participate in daily safety briefings.
• Ensure dust control, noise levels, and environmental compliance are maintained.

Equipment Protection & Troubleshooting

• Monitor lubrication systems, hydraulic pressures, motor loads, bearing temperatures, and vibration indicators.
• Detect abnormal conditions and coordinate immediate corrective action with field operators.
• Respond to crusher trips, alarms, and interlocks to safely restart equipment.

Coordination & Communication

Communicate with:

• Field attendants
• Maintenance teams
• Control room process operators (downstream)
• Mining dispatch (ore delivery)

• Provide clear instructions during start-ups, shutdowns, and maintenance interventions.

Quality & Production Control

• Maintain consistent ore feed according to metallurgical specifications for zinc beneficiation.
• Monitor ore type changes and adjust operational parameters accordingly.
• Record hourly production, downtime events, and shift log entries.

Housekeeping & Documentation

• Maintain accurate shift reports, production logs, and incident records.
• Ensure the control room is clean, organized, and secure.
• Assist with risk assessments, SOP reviews, and continuous improvement initiatives.
