Jul 10, 2020 The plant uses three stage crushing, and conventional rod and ball mills with a flotation and dewatering circuit to produce a copper gold concentrate. When the mine is up-and-running, it mine moves 80,000-90,000 tonnes of material per day, the mill has a capacity to process 17,800 to 22,000 tonnes per day tpd of ore depending on hardness.
CIRCUITS S.Morrell INTRODUCTION As little as 10 years ago a conventional comminution circuit in many metallurgists mind would have conjured up pictures of crushing-ball mill or rod mill-ball mill circuits. Today it is not common to find such circuits in operation, let alone being built. Autogenous AG and semi-autogenous SAG mills now
Dec 01, 2006 A third data set was used as an independent case to validate the Lupin grinding circuit model built based on the other two data sets. The particle size distributions of the tube ball mill discharge and hydrocyclone underflow and overflow streams have been given in Table 1, Table 2, respectively.The particle size distribution curves of the above-mentioned streams can be seen in Fig. 8, Fig. 9.

The HPGR-ball mill circuit when grinding to 75 um compared to 160 um used an extra 4.6 kWhmt, but for the SABC circuit it only used an extra 1.8 kWhmt. The reported SABC circuit power for the 160 m grind size was based on actual site data. JKSimMet was used to fit a model to site DCS data.

Maintaining the work balancebetween the primary SAG mill and secondary ball mills is an overlooked bottleneck, and thus opportunity, in an increasing number of circuits worldwide. As circuit capacities are expanded by releasing the SAG mill bottleneck, the work is progressively passed on to the downstream ball mills.

AGSAG and ball mill circuit data is also very poor. Use of equation 2 shows a very different picture, the results being illustrated in Figure 7. This shows that on average the M operating work indices of AGSAG and ball mill circuits are very similar and hence energy utilisation efficiencies are similar. Also

Circuits diagramming AG mill Ball Mill Crusher as well as AG Mill Pebble Mill image 135-6-21 AG Mill Ball Mill Vertimill. Pebble mill is replaced by a ball mill or a Vertimill in the previous circuit. This is used when there is not enough pebbles available in the circuit, or all autogenous grinding produces too much fines
The mills SAGballflotation circuit was initially designed for 35,000 mtd. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mtd. However, the increased circulating load led to overloading of the original 12 x 28-ft single-deck SAG mill
Jul 10, 2020 The grinding circuit consists of two parallel rod millball mill circuits and a pebble mill circuit. Crusher product is first split between two rod mills where water is added to form slurries. The rod mill discharge is pumped to the primary hydrocyclones that classify the particles by size.
Apr 03, 2014 2. James Didovich 2014 JKSimMet V6 4 JKSimMet Overview JKSimMet is a package developed by the JKMRCJKTech for the modelling and simulation of comminution circuits. It includes models for crushers, autogenous mills, ball mills, rod mills, screens, and hydrocyclones. It is a closed package you can not add your own process models.
The ball mill has higher circulation load, it generates only 30 -35 of actual fines you require to be called as product. If your product size needed is 100 passing 45 micron, then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again.
