Vertical Mills. Medium-speed air-swept vertical mills almost entirely dominate the main bituminous coal-firing applications because of their • Lower power consumption • Superior dynamics • Light weight • Better plant layout. Since they are smaller in capacity, it is also easier to build redundancy to improve plant availability.
Single Pass Air System: With a single pass air system, air is drawn into the mill base, travels through the classifier, bag filter and fan and is then vented out to atmosphere. In addition to being dust free, the air swept grinding zone prevents over-grinding by the air stream lifting the particles of certain sizes out of the grinding zone.
Air-swept mill Air-swept mills with one grinding compartment are used for the combined grinding and drying of very moist materials because large quantities of low-temperature gas can be passed through its drying chamber. This mill can accept ores up to a lump size of 15 mm (in special cases up to 30 mm) and a moisture content of up to 15 %.
