### PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL

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

### Ball Mills - an overview | ScienceDirect Topics

The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three

These mills can also utilise large quantities ... meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding. The mill can be used for pre-grinding and

### Dipl.-Ing. Th. Fahrland, Dr.-Ing. K.-H. Zysk, Loesche

utes. Individual cement particles will be ground from one to three times in a VRM before being offered to the classifier, whereas repeat grinding in a ball mill is virtually uncounta-ble because of the grinding mechanism. Finally, while a ball mill will have a recirculation factor of 2 to 3, this increases
