In discussion: Coal Mill Safety. At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe.
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.
