     · Clinker burning is well suited for various alternative fuels. In order select a suitable alternative fuel, a commercial modelling tool (ASPEN PLUS®) is used to model the four-stage pre-heater kiln system of a full-scale cement plant (clinker production ∼2900 tons/day), using petcoke as fuel. The goal is to optimise process control and ...

  • Clinker Cooler

    Clinker leaves the cement kiln usually at more than 1200℃ and it carries the heat content about 1250-1650 kJ/kg. So it needs to be cooled in order to: improve the cement quality and the grindability of clinker. When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited. Even if some of them have crystallized ...

    At this stage, ground raw materials will be sent into the cement kiln and be heated at a high temperature to produce chemical reactions with each other, eventually forming clinker. In addition, clinkers that just complete the calcination will have a high temperature, thus a cooling machine is usually placed behind the rotary kiln so that the clinker can go directly into the cooler for dropping to normal temperature.
