Being completed preheating and pre-decomposition, the raw materials will be fed into the rotary kiln for clinker sintering. In the rotary kiln, the pre-decomposed carbonate will be further decomposed rapidly and experience a series of solid phase reaction, generating many solvent minerals. When the temperature rises up to about 1300℃, the solvent minerals will be liquidized. Then components such as C12A7, C2F and C2S dissolved in the liquid phase will react with CaO to produce a large number of clinkers.
When cement clinkers sintering is completed, the temperature will decline, and the extremely hot clinkers discharged from the rotary kiln will be cooled by a cooler to a temperature the conveyors, storages and cement mills in next processes can bear. In addition, the sensible heat of the clinkers will be recycled so as to improve thermal efficiency and clinker quality.
According to various fuels and scales, Haijian can offer pulverized coal combustion system, natural gas combustion system, and heavy oil combustion system to our customs so as to assure them of maximum benefit.
