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 systems grinding efficiency.
Nov 27, 2020 Working principle of cement mill separator The material enters from the feed pipe and is scattered into the rising airflow through the dispersion plate. The pulverized medium debris in the material overcomes the falling resistance of the rising airflow under the action of gravity and is discharged through the slag discharge outlet.

Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
Cyclone Mill. The concept of the LV Cyclone is a design with the inlet pulled as far away from the outlet tube as possible. The roof spirals downwards to avoid re-introducing circulated gases into the new gases entering the cyclone. The unique body design further ensures an effective separation of gas and material.
