  • Manufacturing - the cement kiln - Understanding Cement

    The dry process is much more thermally efficient than the wet process. Firstly, and most obviously, this is because the meal is a dry powder and there is little or no water that has to be evaporated. Secondly, and less obviously, the process of transferring heat is much more efficient in a dry process kiln. An integral part of the process is a ...

  • Differences between Wet Cast and Dry Cast Concrete

    Wet cast concrete is often used in the precast industry, where it is cast in forms and stripped, finished and marked prior to shipping. Wet cast is often used for larger pieces that are more complex and need flow-ability in the concrete in order to consolidate around reinforcement and throughout the form.
