However, in the low LD ratio rotary kilns, combustion products passed straight out of the kiln, and clinker was found to be over-limed and quick-setting. A lower-lime rawmix had to be made, and gypsum had for the first time to be added to control the setting time.
The hot clinkers from the rotary kiln go to coolers which consist of series of tubes parallel to kiln in which air is forced through. As a result of this, the clinkers cool down while the air gets heated.
