The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
In his approach the total specific energy of the entire AG/SAG circuit is firstly predicted using the SAG mill feed F80 and the ball mill cyclone overflow P80. Morrell's model (Morrell, 2011) relates the feed, mill geometry and operating conditions to the specific energy of the circuit. However, the F80 is not enough to represent properly ...

of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills. This product slope averages less than 0.5 when plotted on log/log paper and therefore contains an extra amount of ne material fi compared to a PSD, having a 0.5 slope. This fi ne material,
W Total = WSAG + W Ball Mill (2) Where W is the grinding mill work input in kWh/t. For the above reason, the Starkey SAG mill was built in 1991 to measure the energy required to grind ore to a size of 80% passing 10-mesh or 0.17 mm (T80) by grinding small drill core samples to precisely that size.

Alex G. Doll C O N S U L T I N G L T D TECHNICAL MEMORANDUM November 28, 2019 TO: UBC MINE331 CLASS FROM: ALEX DOLL, ALEX G DOLL CONSULTING LTD. SUBJECT: SAG MILL + BALL MILL CIRCUIT SIZING Summary: Most large tonnage mineral processing facilities consist of a primary SAG milling and secondary ball milling grinding circuit.
The Cadia grinding circuit was designed to treat 17 Mtpa of monzonite ore and to operate at 2065 tph with 94 percent availability. Addition of volcanic ore would reduce throughput. The circuit consists of a single open circuit SAG mill with two parallel ball mills in closed circuit with classification cyclones.
Grinding circuit design tools, including for SAG mill-ball mill circuits, and geometallurgy energy models are available to subscribers. The online library of technical articles contain several papers on metallurgical topics including comminution modelling, mass balance calculations and laboratory comminution testwork program information.
Doll (Doll, 2012) considering the various power losses in the transmission system. The estimated SAG mill power includes a correction for the interstitial mill filling. In the case of the estimated ball mill power, the power was calculated using the Bond methodology. Table 4 shows the principle parameters obtained.
The circuit consists of a 60 x 113 primary crusher, two 16 MW SAG mills and two 16 MW ball mills. All four mills are twin pinion with wound rotor motor and gearbox drives. Provision for pebble crushing is provided for primary (hypogene) ore treatment later in mine life. The derivation of the mill's specific
At that time the grinding circuit featured the largest of a kind SAG mill at 12.2m x 7.92m and two 8.2m x 13.6m ball mills. The plant met the nameplate capacity in late 2011 but had some challenges in upstream and downstream plant areas. It was good to see Dave at the conference, another of my mid-1980s CSM students.
This will usually be feed belt sample in the case of a SAG mill, or a sample from a transfer pipe or launder in the case of a secondary ball mill. The operating specific energy consumption is first...
These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.
