Current Preparation Plant Utilization Maintenance Practices

摘要

1. Decreasing maintenance clock hours to achieve higher plant throughput is successful for many operators.rn2. Improved maintenance practices and use of wear resistant materials are responsible for the ability to decrease weekly maintenance hours (clock) to as few as 12 on an ongoing basis.rn3. Many operators feel the need to have additional maintenance personnel to maintain the desired throughput and availability.rn4. Coal producers should consider alternative shift scheduling for maximum plant utilization and a productive work force.rn5. Alternative scheduling, coupled with a multi-skilled work force, can reduce capital costs for new plant installations by as much as 40%.rn6. Availability can be maintained operating 24-hour days up to 6 1/2 shifts/week.
