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).

The circulating load can be defined as a process flow (mass or volumetric) of a given material that returns to a unit operation after failing in some selection criteria. This disapproval may be due to an imperfection in the selection equipment or due the material being out of the specification accepted by any subsequent step in the process.
