The underflow of the secondary cyclone is recycled back to the ball mill for grinding and the final product is the overflow which goes to a flotation circuit as feed. Water is added to both sumps to facilitate the flow of the slurry smoothly within the circuit.
This circuit is usually adopted in modern practice, but with a bowl instead of a straight classifier, if necessary, in the closed circuit of the secondary ball mill.
The HPGR-ball mill circuit comprises a reverse-closed secondary crushing circuit prior to a closed HPGR circuit, followed by a reversed-closed ball-mill circuit with cyclones (See Figure 2). The vibrating screen decks were set to an aperture size of 32 and 4 mm for the secondary crushing stage and HPGR screen circuit, respectively.

Secondary milling to between 67 and 72% passing 75 µm, with natural fines grits. Comminution Circuit Description The KP1 plant consists of two primary ball mills converted from rod mills, which are running in parallel, and a secondary ball mill. Figure 1 shows the primary milling circuit, and Figure 2 the secondary milling
The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.
For many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ...
Ball mill Wikipedia. The effect of the design of a secondary grinding circuit. Currently most circuits treating UG2 platinum ores involve two stages of grinding and flotation Primary grinding usually involves a ROM ball mill followed by flotation secondary ballmilling of the flotation tails and secondary flotation The secondary ball mill is operated in open circuit
effort to improve the grinding efficiencies in a secondary ball mill. A mill audit of the five (5) NSPC secondary mill circuits was performed by Control I nterna ti ona l, Inc., M. A. Hanna and NSPC personne 1 in November, 1988. The various mill circuit samples were processed at the NSPC plant lab.
The ball mill oversize feed factor (EF 4 BM) is always calculated with the ball mill work index. The optimal feed size for the EF 4 BM is always calculated using the rod mill work index. where: F 80 = 2100 µm; P 80 = the specified circuit product size, µm; Secondary and tertiary crushers
The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.
