SAG mills mimic the same shortcoming. It follows that in order to obtain the speciﬁ c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an inefﬁ ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.

ABSTRACT Simulation work was carried out to analyse how feeding a finer size distribution to a single stage SAG mill in closed circuit with hydro cyclones at Freda Rebecca Gold Mine would affect throughput and specific energy consumption using an Excel based milling process simulator developed by Hinde, a comminution specialist who has worked for Mintek for many years.

#### Open Circuit Configuration - IsaMill™ Advantages | Isamill

Feed to the IsaMill™ passes through 8 consecutive grinding stages between the discs before it reaches the internal classifier. Other mills with just one grinding stage require closed circuit cyclones and high recirculating loads and still don't produce product size distributions as steep as the IsaMill™.

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ...

The first two types may be called single-stage operation, while the last two are two-stage operations. Most AG/SAG mills operate in open circuit (Figure 9.3) when the product size is usually coarse.Usually, provision exists for installing a classifier such as a straight screen, a trommel or a curved DSM screen to remove critical sized pebbles (scats).

#### IsaMill - Wikipedia

The coarse particles (known as "oversize") are returned to the mill and form what is known as a "recirculating load" that takes up a significant portion of the capacity of the mill. The centrifugal action of the product separator results in only the fine particles leaving the mill and the recirculating load …
