Apr 01, 2013 1. 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).
Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill – cyclone circuit is around 250%. This value is used as guideline for the design of new circuits as well as to assess the performance of existing circuits.
AG Mill + Pebble Mill. Two stage AG-grinding with the primary mill in open circuit and the secondary pebble mill in closed circuit. The pebbles screened out from the primary mill or recirculated to the primary mill based on size. Circuits diagramming AG mill + Ball Mill + Crusher as well as AG Mill + Pebble Mill.
If rods are used instead of steel balls, the mill is referred to as a ‘rod mill’. Closed-Circuit or Open-Circuit. Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill’s output back to the ball mill for further size reduction.

The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow. The slurry stream is classified at Cyclone 1 with the overflow going to the flotation circuit. Cyclone 1 underflow constitutes the fresh feed to the second milling circuit that runs in closed circuit with its own cyclone (Cyclone 2). Ball

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.
Double helical feeders used in closed-circuit with classifiers; Spout feeders preferred when using a closed-circuit with classifying cyclones.
