Open and closedcircuit grinding system. The grinding mills are also used in either open circuit without returning a coarse part of the ground material to the feed or the closedcircuit grinding system with recycling. In the latter case, the separation process plays an important role in the improvement of the grinding performance.

A dry operated, horizontal stirred media mill was used for the fine grinding of limestone and compared in open and closed circuit modes. It was found that the choice of grinding aids as well as the stirrer tip speed are crucial for the mill operation, especially in terms of the grinding efficiency and the transport behavior through the mill.

Some of the admixtures allow fineness to be increased in open circuit mills, whereas in closed circuit mills, considerable production increase can be achieved at the same fineness. The difference is due to the fact that in the latter, the fineness of the product is established by the parameters of the airseparator.

On the one hand, GA effects were shown to be completely different for open and closed grinding circuits, even when the same mill is used [24]. As shown in Fig. 4, high additiveinduced flowabilities may be detrimental in the open grinding circuit, whereas they are advantageous in closed circuit operation. Especially for high target finenesses ...
