mill absorbed power and ball filling degree As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate The risk of underloading or overloading the mill is an additional factor The grinding is done in a ball mill The cement discharged by the mill is passed through a separator, fine particles being removed to the storage silo by an air current, while the coarser particles are passed through the mill once again Concrete Technology/ Ch1 Dr Basil Salah ٦ Comparison between wet and dry process Wet process Dry process 1 Moisture content of the slurry is 3550% 1 Manufacture of Portland cement University of Technology Getting more from the cement ball mill with the Fives FCB TSV™ 3rd generation classifier*) Effizienzsteigerung bei der Zementmahlung in der Kugelmühle durch Einsatz des Fives FCB TSV™Hochleistungssichters der 3 Generation*) (static classifier) to a classifier equipped with a rotating turbine (dynamic classifier), which at first was a small axial turbine (1st generation) and by the end Getting more from the cement ball mill with the Fives FCB The laboratory type ball mill was loaded with clinker and grinding aid mixture and operated for 40 minutes Samples were taken from the stopped mill, and the SO 3 level was checked Gypsum was added into the mill according to the final target SO 3 level [305% ± 005], and the mill was operated for another 40 minutes At the end of 80 minutes milling, cement samples were taken separately for Effects of Adding Boron Compounds to Glycol Based Grinding Raw mills usually operate at 7274% critical speed and cement mills at 7476% 32 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg w: Angular velocity of the mill tube in radial/second w = 2*314*(n/60) Di: inside mill diameter in meter (effective mill diameter) n: Revolution per minute in rpmCement mill notebook SlideShare
