Discharge from each SAG mill will be cycloned to recover the finished product whilst unfinished product will be evenly split between two ballmill circuits. The four ballmill circuits will be closed by hydrocyclones. The finished product from all cyclones will gravitate to two surge tanks, via instream particle and chemical samples, prior to pumping to the flotation area.
SAG mill is fitted with a dual pinion drive ( MW per pinion) and is driven by a variablespeed drive comprised of a SER/Hyper synchronous drive. The 24 ft × 39 ft (13 MW) ball mill is driven by dual, MW woundrotor motors through reduction boxes and gear and pinion drives. The SAG mill discharge is screened on a rotating trommel screen
Zijin Mining Group has chosen an FL gyratory crusher, SAG mill and ball mill for the Majdanpek mine, part of the Chinese mining company''s majority owned Zijin Bor copper mine, in Serbia. The delivery of the equipment to Majdanpek, 180 km from Belgrade, is expected to occur between 12 and 18 months from now, with the project estimated to reach completion by the end of 2020.
· Power model on data of four SAG mills, treating sulphide copper ores in Chile. • Specific energy model on data of four SAG mills. • Models include the variable % −6″ +1″ in the SAG circuit fresh feed. Abstract. Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual comminution circuits consist in most of the cases in coarse crushing, SAG
These enhancing technologies accompany our grinding mills and make the grinding process more efficient, which adds significant value to the whole concentration process. These technologies include online particle size analyzers for the feed and discharge (Outotec RockSense and Outotec PSI® particle size analyzers), mill charge measurement tools (Outotec MillSense®), and advanced process
Sarcheshmeh copper complex SAG mill This work was carried out at the Sarcheshmeh copper complex located in SE Iran. At the new concentration plant of the Sarcheshmeh copper complex, which comprises two parallel phases, two ( × and × m) SAG mills are used to grind a feed all under cm that is the product of a gyratory crusher. The discharge of the SAG mill is

Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20100 mm). Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed circuit with classifiers whose circulating loads reach as high as 400500%. The geometry of radial and curved pulp lifters is such that the
The apron feeders discharge on to a m wide conveyor belt which carries the ore into the mill grinding circuit. The primary grinding circuit consists of an m diameter × m grinding length, 5,222 kW SAG mill in closed circuit with a single deck vibrating screen and a cone crusher. The cone crusher product discharges directly on to the

Pilot plant mills can have very different breakage and discharge functions than large mills and the impact of this on specific energy can be significant, particularly if the discharge performance in the SAG mill is not carefully considered. Sossego The Sossego project (Delboni et al., 2006 and Bergerman et al., 2009) treated a higher copper
CiDRA CYCLONEtracSM at Kennecott Ut Copper Dylan Cirulis (Kennecott Ut Copper), Jerin Russell (CiDRA Minerals Processing) Introduction . Rio Tinto''s Kennecott Copperton Concentrator has four grinding lines each consisting of one SAG mill feeding two ball mills in a closed circuit with a hydrocyclone battery (Figure 1). The aim of the ball mill/ hydrocyclone circuit is to produce the
The slurry discharges out of the mill from the grates in the slot between the grates and the head. The oversize falls into a bucket wheel on the discharge end of the trommel, gets picked up as the trommel revolves and falls into the stationary rock box. A water jet then squirts that oversize back into the mill through the conical discharge tube.
