ROTARY DRUM MONOCULAR COOLER KILN This rotary drum monocular cooler is an important device in the rotary kiln system Clinker whose temperature is 1000 to 1200℃ driven by the rotating cylinder can take full heat exchange with air so that their temperature can be cooled down to less than 200℃ and meantime the quality and grind ability of the clinker are highly improved After cooling the clinker the air reenters into
