Cement Mill Separator - Cement Plant Equipment Design
Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.
Energy-Efficient Technologies in Cement Grinding | IntechOpen
The coarse particles drop back into the centre of the grinding compartment for further size reduction, whereas the fines together with the mill air leave the mill and the separator. The separator controls the product sizes from 400 to 40 μm. The moisture of the mill feed (cement raw material) can amount to 15–18 %.
