The fused mass turns into a nodular form of size 3 mm to 20 mm known as clinker. Then, the clinker is cooled under controlled conditions in a rotary cooler. The clinker is stored in silos or bins. Generally, the clinker weighs about 1100 to 1300 gms per liter. The liter weight of the clinker indicates the quality of the clinker.

The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were "straight", the ...

Single-barrel cooler is one of the important equipment in rotary kiln system. The clinker from rotary kiln (1000-1200 C) exchanges heat with air sufficiently through animal material in the rotary belt of the barrel, so that the material can be cooled to below (200 C). At the same time, the clinker quality and grindability can be improved.
