  • SAG Mill Grinding Circuit Design -

    SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency

  • Optimizing your SAG mill operation -

    In the past, when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy efficiency of a plant often rests largely on the SAG mill operation. As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills.

    01.01.2016· Such replacements lead to savings in capital expenditure in a plant design. The SAG mills have been mostly used for milling hard gold and copper ores with quartz, ultramafic or green stone as host rocks. The Bond work index of these ores ranges between 12 and 14 kWh/t. Subsequently, SAG mill application has been extended to softer ores, such as bauxite and clayey hard-capped gold ores.

  • Autogenous AG & SAG Mills for Sale -

    SAG mills tumble mainly ore but they use up to 15% volume of steel balls to assist grinding. Semi-autogenous mills are more common. The AG Mill or SAG grinds primary crusher product and prepares it for final grinding in a ball mill. Its product is usually passed over a large vibrating screen to separate oversize 'pebbles' from correct-size particles. The correct-size material is sent

    SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed.
