Efficiency of separation, fineness, particle size distribution. The classifier can separate particle sizes of 30m 250 m (and generate products with residues of 3% R 30m 3% R 250 m). The mechanical components of the classifier in combination with process influencing parameters can produce various particle size distributions.

This can be seen as a separation of coarse aggregate from the mortar, caused from either the settling of heavy aggregate to the bottom or the separation of the aggregate from the mix due to improper placement. Some factors that increase segregation are Larger maximum particle size (25mm) and proportion of the larger particles.

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.
