Comminution Theory & Process Equipment

In closed circuit grinding the feed enters one end of the mill and is discharged from the other end into some type of classifier. This classifier is to limit maximum particle size removed from the mill circuit. The oversize material is returned to the grinding mill for additional size reduction. Such material returned to the mill is defined as ...

Batch Ball Mill for Open or Closed Circuit Grinding

The batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. Different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. The batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.

Abstract. The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
