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.

The total inlet moisture must be kept under 1,5%. The container number #2 has a 450kW ball mill of extreme simplicity to ensure maximum reliability and low maintenance. Nevertheless today's most advanced technology has been used in its conception and construction. This ball mill is ready to be installed as it comes on a flat-rack container.

The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.

Water Cooling in the Cement Mill is accomplished by injecting and evaporating water at the outlet / inlet end of the mill. The water vapour is removed from the mill together with the ventilation air, which must be so ample that the temperature does not drop below the dew point anywhere in the pipes, dedusting filter, etc after the mill.

The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary cement is being ground, to 85-95% for extremely fine cement products. It is important for system efficiency that the minimum amount of material of finished-product fineness is returned to the inlet.
