Modeling of Coal Mill System Used for Fault Simulation MDPI

The mediumspeed coal mill system is mainly composed of raw coal bunker, coal feeder, coal mill, primary fan, sealing fan, hot and cold air regulating valves. The coal feeder transports the raw coal from bunker to mill for grinding. The primary air is divided into two paths after being pressurized by primary fans.
