The coal is usually stored in the bunker before feeding, and the flow of coal is controlled by a gate valve. After coal is fed into the feeder it passes through the conveyor belt and enters the coal mill where it gets converted into a fine particle, mixed with an equal quantity of air, and finally used for combustion inside the furnace.

Castle Gate, Utah, was once a busy coalmining town located in Carbon County. It took its name from a nearby rock formation near the mouth of Price Canyon that has two sheer sandstone walls on either side of the Price River. The first coal mine, Castle Gate Mine #1, opened in about 1886 after the Denver and Rio Grande Western Railroad ...

Each box is provided with two knife gate valves, at inlet and outlet flanges, to disconnect the mill (at positive pressure) from the downstream equipment (at atmospheric pressure). The rejects are intermittently extracted by short MRS ® conveyors and dosed to the main MRS ® conveyor, which collects the rejects from all coal mills. Finally, a ...

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.
