When a mill is in closed circuit with a classifier, it will handle a circulating load of several times the amount of the original feed. The correct operation of a mill with proper load of balls and pulp or ore feed is determined by sound or by power meter. Normally, the sound is a rumble, whereas from a more or less empty mill there is a rattle.

developed three standardised characterisation tests (crushing, rod milling, and ball milling) that were compared to results from a pilot plant containing closed-circuit crushing, open circuit rod milling, and closed-circuit ball milling. From these comparisons, empirical constants were applied to the laboratory test results so that the pilot

The simplest closed mill–classifier circuit is that according to Fig. 1b. The produced material at the outlet of the circuit has a certain maximum size which is determined by the classifier. In a closed mill–classifier circuit all flows other than the feed and the product are internal and are usually not quantified.

The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%. This efficiency was chosen as an industrial practice ''average'' from the data presented in Fig. 6.

The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.

03 Use of Grinding Machines. Ball mill is not suitable for open-circuit process. Because ball mill itself does not have the ability to control grinding particle size, there are both qualified fine particles and unqualified coarse particles in the discharge. On the contrary, rod mill is suitable for open-circuit process.
