Following a successful commissioning and start-up, we believe that two grinding lines at Las Bambas, Per , each consisting of one SAG Mill and one Ball Mill this mill combination is uniquely specific to Las Bambas ore types, are operating at design throughput of close to 140,000 tpd and within the range predicted by DJB from a managed ...
stage AVC grinding circuit flowsheet was developed. The AVC circuit is shown in Figure 1 and consists of a pebble crusher and AG mill in closed circuit with primary cyclones. The secondary stage of the grinding circuit consists of one Vertimill VTM 1500 WB 1.1MW in closed circuit
Closed-circuit grinding Closed-circuit grinding is a size-reduction process in which the ground material is removed either by screening or by a classifier and the oversize is returned by integral classification to the mill for further processing.

Apr 15, 2004 A closed-circuit grinding system, using a continuous vibration ball mill has been applied to the production of fine particles. However in most cases, the operational conditions are determined empirically. The reason for using empirical operational conditions is that it is difficult to estimate grinding performance.
This circuit had problems of over-grinding the galena-bearing minerals as the cyclones returned the smaller but heavier galena particles and coarser but lighter gangue particles to the underflow for further grinding. The effect of this phenomenon is illustrated in Figure 5. Figure 4 Closed-Circuit Tower Mill for Treating Bulk LeadZinc Concentrate
