4. Rotary coolers
The rotary cooler is the oldest clinker cooling system installed on rotary kilns.
Mechanically simple (figure 16 ), it presents two process difficulties when used on high-capacity furnaces:
candle formation at the clinker chute on the inlet side;
fluctuating air velocity in the lift zone.
The first of these problems can be solved by using a water-cooled chute or by equipping the chute with an automatic ringing (cleaning) system, while the second can be solved by increasing the diameter of the tube between its two tyres.
