Cyclones lined with KALOCER high alumina
round the cyclone in a decreasing order in terms of circular diameter. This action causes the dust particles to settle down to the bottom of the cyclone, The air, which is now clean, escapes through the vortex finder to the atmosphere. The accumulated dust however drops down through the opening at the cyclone base (6). 3.1.2.
