bunker is fed hv gravity through a feeder to a pulverizer with a single outlet. In the mill, the coal is simultaneously pulverized and dried. Hot air to dry the coal and transport it out of the pulverizer is pro- vided by a fan and an air heater. The temperature of this air may be as Ilot as 650" F depending on surface moisture.

Since mill load level can be indicated by mill coal mass flow, coal feeder speed is used to represent 108 G.Q. Fan and N.W. Rees mill load level. During the simulation, a (+10%) step signal was applied to the D mill feeder as a disturbance so that dynamic performance of the auto mill load sharing control algorithms can be tested.

b = a: ρ g ( 1 + g ) (2) where a = (2 π f)² X f = amplitude of applied acceleration . Without vibration (that is a = 0), h. b = 0.1 m = 100 mm, a substantial amount. To reduce h. b. to say 10mm, an acceleration a = 9.2 g is required. There are many combinations of frequency and amplitude to achieve this. For instance, a frequency of f = 151 ...
