SAG mills with a rated power of up to 35 MW. As well as ever larger SAG mills, ball mills are also expanding in size. In the late 1990s the trend moved towards using GMDs to power these larger ball mills, as well as using the drive to vary the speed. GMDs quickly moved from 20' ball mills, expanding to 24, 25 and then 26' mills. In early ...
Ball Mills have a higher degree of efficiency than SAG Mills due to their smaller size and have more area for grinding particles, leading to faster grinding. On the other hand, SAG Mills have a larger and deeper drum that provides larger lifting force which increases grinding efficiency. In addition, due to its larger size, SAG Mills consumes ...

Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

Early SAG mill designs using gear drives were limited in the amount of power that could be applied to the pin-ions, 3.7 MPa (5000 hp). The exception to this design was the Hibbing taconite operation. It used two4.47 MPa (6000 hp) motors to drive a 1I-m-diam x 4.5-m long (36-ft-diam x 15 ft) autogenous mill. However, recent SAG mill designs now ...

Difference Between Sag Mill vs Ball Mill. 1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

What''s the Difference Between SAG Mill and Ball Mill. SAG mill vs Ball mill Crushing ratio The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm.

ommodated in the liner design and changed when and if necessary.For large mills, using 125 to 140 mm (5 to 5-1/2 in.) feed ball size, conventional new lifter-liner dimensions are around 300 to 350 mm (12 to 14 in.) overall height above the shell, with around 10. mm (4 in.) plate thickness and around 150 mm (6 in.) top.

SAG Mill Components. Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural …
3.2 Mine-to-Mill The feed size to AG and SAG mill circuits has been demonstrated to have a significant impact on throughput with effects such a that illustrated in Figure 7, being commonplace. Modifying blast design and primary crusher operation can significantly influence AG/SAG mill feed size, hence giving a potentially cost effective way to
The larger units can also be matched with the SAG mill in SAB/SABC configuration. Stirred mills (Regrinding). Finer regrinding or ultra-fine grinding is a frequent requirement in pilot plants and ALS has a range of units that can run continuously in pilot applications. The following mills are located at Balcatta: ISAMill tm, Deswik, and ...
Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is …
If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to ...
