• The clinker manufacturing process Al badia cement

    The clinker manufacturing process. The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality. The preheating of the material takes place in preheater cyclones fitted with a precalciner fired with petroleum, natural gas or coal.

  • Cement Production Pavement Interactive

    Manufacturing cement at the Lafarge Seattle plant is by a "wet process". As a result, raw materials are mixed with 30 to 40% water during grinding to form well mixed slurry. This wet process is advantageous due to the increased compatibility with wet climates and more uniform blending of raw materials prior to the kiln, along with lower kiln dust emissions.
