A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
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. The transfer diaphragm allows
