The "airswept" method of operation of a mill eliminates the conveyor system which was often used in earlier types of plant to transport the product to the classifier and the oversize material from the classifier back to the mill. It is clear, however, that such a system can only be used successfully when the material undergoing treatment ...

1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding ( its capacity to produce the desired final product).

We are working in a plant with single stage grinding using three parallel wet three compartment ball mill. Each ball mill operates in a close circuit with Classifier. The fineness of ball mill product is OK so the circulating load is insignificant (44 Kg/h). The overall data of each ball mill circuit are following:

Many older operations have rod mills in combination with ball mills. Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed cm.

Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills. They have much higher specific grinding energy and from there are for production of finer products than conventional ball mills.
