Feb 01 2011 1 introduction tube mills having multichambers are traditionally used for cement grinding either in open or closed circuit operations in the first chamber larger balls 100–60 mm are used for coarse grinding while the smaller balls 40–15 mm are used for fine grindingthe chambers are separated by an intermediate diaphragm which allows the passage of the fine particles to the second
Feb 01 2014 mill grinding flux is related to new feed and return flux however adjusting the circulating load will cause a series of chain reactions for instance reducing the circulating load will cause ckp mill vibration and add the output material flux of cement clinker as shown in the eq so the production of cement clinker is adjusted
