The mill is an Atox 30 with a hot gas generator with Fuel Oil Nr 6 as fuel. I'm looking at alternatives to reduce or change the current fuel. So I need heat balances of the entire mill including the hear generator, VRM, cyclon, ventilator and electrostatic filter. I have registry of material humidity, heat generated and production of raw meal.
