Raw mill The raw mill is usually a large vertical roller mill (VRM) that is designed to grind with a specific material to air ratio. Too little air flow and the mill can plug, too much air flow and the fineness can decrease, the additional fan power is expensive, and the wear through out the system is increased. The large power requirement of
