  • The cement kiln

    In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln. The dry process is much more thermally efficient than the wet process. Firstly, and most obviously, this is because the

  • Rotary kiln - Wikipedia

    Principle of operation The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its longitudinal axis. The process feedstock is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same

  • Process monitoring at the calciner | SICK

    In many cement plants, there is a calciner with a secondary firing that takes place between the preheater and the rotary kiln. The process gas components in the kiln exhaust gas are continuously monitored in order to optimize the operation of the calciner. An MCS300P HW hot wet measuring process gas analyzer system with a back-purging gas sampling probe is used to handle this task. The

    This technology was once considered infeasible in cement plants, but its application in thermal power plants and coal-fired boilers is now mature and has demonstrated the possibilities for cement producers. However, SCR is still a relatively immature technology in the cement industry and further optimisation work is required.
