An extremely important step in the cement process is to proportionally feed these materials to the raw mill to ensure the correct "blend" of these materials. One can think of this process as a "recipe" for making various types of cement. Generally, cement customers are looking to control Lime Saturation Factor (LSF), Silica Modulus (SM) and Iron Modulus (IM). The raw materials, now ...

We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.
