What are Coal feeders? Principle, components ...

Principle of Coal Feeder: Coal that has been crushed with a Crusher will be transported by belt conveyor to Coal Yard for stock and Coal Bunkers. From the Coal Bunker then the upper strobe/damper is opened, the coal from the bunker enters the loading area of the coal feeder, then the belt conveyor runs at a speed set by Variable Speed Drive (VFD).
