Inner Rotary Kiln Each Parts Working Speed Analysis:

Inner rotary kiln material working speed change with different condition, material working speed has relative to air discharging capacity, rotary kiln speed, inner rotary kiln resistance, material liquid and material size and so on.
Calcination area and exothermic reaction area, material working speed is fastest, because this area has large amount of gas outlet, increase material layer porosity rate, make powder material flow property better. As the calcined material area exist with liquid, increased granule angle of repose, so, working speed is slow. As cooling area with collar at rotary kiln inlet port, making material density thickness bigger, then reduce material working speed.
