The cement is taken over by a transport relay and stored in the cement silos, the coarse part returning to the mill for a new crushing. The cement is then taken up and transported to the silos, either with a conveyor belt and elevator or with a system of pneumatic gutters and elevators [ 39 ].

The greater the difference between the fineness of the return and the fineness of the output, the more the powder selecting ability of the cement separator will be improved, forming a lower cyclic load rate and a higher powder selecting efficiency, the cement grinding mill can increase the feeding and increase the output.

Re: VRM and ball mill circulating load. Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.

Methods and systems for controlling a cement finishing mill, and operating the mill at an optimal point, are disclosed. To determine an optimal point of operation, values of mill power and sound are collected and compared to values predicted by a model to determine if the mill is choking. This choking determination is used in one of two processes to determine an optimal point of …

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.
