significance of coal mill fineness

significance of coal mill fineness

Despite the significance of this property, there has not yet been a robust and easy to handle system for the online measurement of coal fineness inside the pipe. EUcoalsizer solves this problem. The system measures the particle size distribution and the coal and air flow inside a measurement volume that is placed at the tip of an insertable lance.
