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.

Air velocity of coal mine ventilation is an important consideration that may cause serious damage. This paper proposes a simple, low cost and effective air velocity monitor (AVM) for coal mine ventilation. The AVM uses the lockin characteristic of vortexinduced vibration (VIV) to sense the air velocity.

The Venturi effect can also be proven by studying Bernoulli's equation, which is: ( v 2 /2 ) + gh + ( P/ρ ) = Constant. Here, v is the flow velocity. g is the gravitational constant. h is the elevation, in the direction opposite to gravity. P is the pressure at any point in the fluid. ρ is the mass density.
