Separator Efficiency Formula derivation. can anybody send me the derivation of separator efficiency formula used by FLS. A long log formula. Also there are other two formulas for efficiency calculation based on recovery of fines & rejection of coarse.
Peru: Germany-based Christian Pfeiffer is supplying grinding and separation equipment for Cementos Inka's grinding plant project near Pisco. A 4.2m diameter 3500KW mill and a QDK 143-Z type separator with gas recirculation, to help dry the raw material without hot gases, are being provided.
Optimization of the Cement Ball Mill Operation ... of the grinding process along the length of the mill. The separator is expected to perform in a way that a minimum of the fines is carried in the coarse reject fraction and sent to the mill for regrinding. The separator's efficiency is determined by drawing a Tromp curve based on particle ...
O-SEPA Separator_Separator in Cement Mill_China Sunlike. O-SEPA separator is the third generation efficient and dynamic powder classifier which has found wide application in the grinding system of cement enterprises. Developed by means of the most advanced technology in the world, this type of separator boasts following characteristics as ...
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.
ment separator mill for cement The mill shell is divided by a diaphragm. Coarse grinding using big balls of up to 100 mm in diameter takes place in the first com- partment. The peripheral wear lining is designed as a lifting or activator plate lining which, with the large balls, achieves a high energy input for comminution.
There are process engineering options for controlling fineness and particle size distribution of the cement by changing the mode of operation of the mill and …
Figure 6b: equation of the regression curve separator feed separator finished product recycle from separator finished cement. The samples were subjected to laser and Alpine granulometric particle distribution analysis. In Table 3 the results of the separator yield, the Tromp curve and the RRB regression line equation are reported.
few fines are returned to the mill and the tromp curves are better and have a very low by-pass. The Sturtevant SD separator is the result of over 20 years of research and development. It comb ines ay t h lg features designed to maximize classification and efficiency performance at lowest operating and maintenance costs.

Again, after assuring stability of mill conditions, dispensing of the amine-based GA started at relatively reduced rate of 460 g/ton (this was due to economic reasons established by the cement company). As earlier, the tube mill and separator parameters were adjusted to ensure stable grinding conditions delivering cement fineness close to that ...
