Raw Mix Design for Raw Mill and Kiln Cement Operation_ English Version.
The first goal in preparing raw materials is a thorough understanding of the raw materials available for the needs of the cement plant.
Most cement plants are built at or near their calcium oxide source, as limestone represents about two-thirds of the mass of clinker.
The composition of limestone, which is generally the most important source of calcium, will determine all the additional raw material requirements to be selected.
The main objective of the design and preparation of raw materials is the kiln feed which enables the effective and energy efficient production of portland cement clinker.
Raw Mix Formulation
There are two equally important goals in designing the raw mix at a cement plant.
On the one hand, the mix must be burnable - that is, it must be possible to achieve an acceptable free lime content in the clinker with a reasonable burning zone temperature, without suffering significant reductions in the production level of the kiln or inordinately short brick life.
On the other hand, market considerations dictate that the composition of the cement be carefully controlled; that is, the contents of C3S, C3A, alkalies, and MgO must be held within fairly narrow, prearranged limits.
For the calculation of the raw mix design, we explain in this video, please watch the video until it's finished.
