AG Mill and SAG Mill. Feeding size: ≤25mm. Capacity: 0.65-615t/h. Output size: 0.074-0.89mm. Applications: It is commonly used in the mineral processing industry and ferrous and non-ferrous metal ore and nonmetal ore processing plants. It can also be used in cement plant, refractory plant, fertilizer plant and smelting plant.
The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process. Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing.

Not surprisingly, some of the advantages of SAG milling are reduced in terms of increased liner wear and increased maintenance costs. Also, pre-crush can lead to an increase in mid-sized material, overloading of pebble circuits, and challenges in controlling recycle loads.

SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and otherwise equal …

At Molycop, we endeavour to be innovative and ahead of the curve with a constant focus on forward momentum - so we can play a leading role in the transformation of the mining sector and improve the way things get done. Explore.
The ideal ball charge volume for a SAG mill is 12% v / v [ 16 ], according to the design objective, and the maximum ball size has a diameter of 150 mm. During operation, however, breakage rates of the shell liners and lifters become extremely high, with a lifespan of only one month when a ball charge volume of 12% v / v was used.
minerals| free full-text | optimizing performance of sabc. The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG ...
