mill will have a recirculation factor of 2 to 3, this increases . ... The application of both the ball mill and the roller mill in the cement industry are explained in detail. The main flow

ball mill is higher than that of a vertical roller mill carrying out the same operations by a factor of between 1.5 and 2, depending on the degree of optimisation of the ball mill. 2. Grinding system options Nowadays, cement producers have the option for using a range of different systems for cement grinding

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

Cement mill specific power consumption – 4. Other systems – 5. De-bottlenecking – ... Grace factor and other ball mill parameters – 8. Mill power – 9. Ball weight and surface area – 10. ... producing poor fuel/air mixing and an intense recirculation zone on one side, while

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

Feb 21, 2015 Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70)
