Therefore, changes in circulating load on a single stage mill may affect the size of the slurry pool and consequently the power draw. Load indication is also very important for high ball charge SAG mills or Run of Mine (ROM) ball mills as changes in power draw resulting from changes in load may be starting point for ball mill media and solids charging generally starts as ...

What is the most reliable method to determine actual circulating load in grinding circuit? A simple one ball mill w/ hydrocyclone. I observed that the most common methods applied are (1) use of water balance taking samples of cyclone feed, cyclone underflow and cyclone overflow.

Actually with the recirculating load of about 250300%, your operations are fine on the ball mills. You only experience high recirculating loads if there is a change in the material being treated meaning the Bond work index tends to be higher for the new material.

The calculations indicate that in order to obtain overload with smaller mills at a constant circulating load, the L/D ratios would have to increase progressively from the initial /1 value for a n diameter mill, to a /1 L/D value for a throughput reduction to 10 percent of the original value. This high an L/D ratio is without precedent.
