• Plan, schedule, and oversee daily plant operations (crushing, screening, conveying, washing, stockpiling, loadout).
• Optimize throughput, yield, and product quality within specification while minimizing downtime and waste.

Quality & Continuous Improvement

• Ensure products meet gradation and cleanliness specs; partner with QA for sampling, testing, and corrective actions.
• Implement Lean/5S practices and small‑capital or no‑cost improvements to enhance safety, quality, and cost.
• Maintain accurate daily reports: production, downtime, safety, training, inspections, and environmental checks.
