Concentration and Recovery Formulas. These are used to compute the production of concentrate in a mill or in a particular circuit. The formulas are based on assays of samples, and the results of the calculations are generally accurate— as accurate as the sampling, assaying, and crude ore (or other) tonnage on which they …

Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph

The concept and theory to best understand a Ball Mill Circulating Load is shown here as an excerpt from Arthur and Ball mill circulating load PPT. Circulating load based on pulp density; Circulating load based on screen analysis

Figure 2.3.11. Impact-hammer mill (EV crusher of FLS). Swing hammer reversible impactors. In these machines, the rock is slammed by the free-swinging hammer against breaker plates arranged circumferentially around the upper part of the chamber and allowed to fall freely from the bottom, as there is no grate arrangement (Figure 2.3.12).

The main difference between secondary crushing and tertiary crushing is the size of the output material. Secondary crushing produces a smaller, more uniform product size that can be fed into the tertiary crushers, while tertiary crushing produces a finer product size suitable for use in the final stages of the comminution process.
