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 ceramic sand rotary kiln is a process of calcining various raw materials such as rock, kaolin and industrial waste slag into ceramic texture granules at a temperature of 950 ° C - 1050 ° C to replace aggregates such as crushed stone in general concrete making. The ceramic sand density is lower than that of stone, and it has strong resistance to osmosis and acid and alkali resistance.
