From the coal yard, the coal is transfer to the mill bunkers through conveyor belt. The bunkers are sized for an effective capacity of twelve (12) hours at BMCR with design coal. Each mill bunker has one hopper, connected to the feeders. Mills operate when the bunker coal gate valves are opened, coal is allowed to flow to the gravimetric feeders.
