  • Major Mines & Projects Mulatos Mine

    28.02.2020· The mill started in early 2012 at 500 tpd which is currently supplied by the open pit mining in the Escondida area of the main pit. Underground mining planned at Mulatos consists of two primary mining methods, longhole open stoping with delayed backfill and modified drift and fill. The preferred sequence for longhole stopes is to mine from the bottom up. Thus the upper development or drill drift

  • Gearless mill drive (GMD) and digital services for Kinross

    Phase One added incremental crushing and grinding capacity to the existing carbon-in-leach (CIL) circuit, which includes an oversized SAG mill and gyratory crusher. For this expansion project, Kinross selected ABB to provide a 26 MW gearless mill drive system (GMD) for the mine’s 40 ft SAG mill, as well as other drives, electrical infrastructure equipment and a long-term service agreement (LTSA).

  • What's the Difference Between SAG Mill and Ball Mill

    The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize. Sometimes, in order to improve the processing capacity of the mill, a small amount of steel balls be added appropriately, usually occupying 2-3% of the volume of the mill (that is semi-autogenous grinding).

  • Mill (grinding) Wikipedia

    SAG is an acronym for semi-autogenous grinding. 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.

  • Ore processing Waihi Gold

    Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing. The trash screen (10) removes wood from the old mine workings that may have found its way into the processing circuit. The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about

  • Difference Between Sag Mill vs Ball Mill mech4study

    SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates inside the drum are responsible for picking the grinding

    SAG mills are very important equipment of industrial mining. SAG mills are commonly used in mining fields. From mined coal, it separates out some precious metals. In the mining, some precious metals found are like gold, silver, nickel, and copper etc. Ball Mills: Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small

  • Ore Hardness Testing -SAG Mill Tonnage Estimation

    For design purposes, you need an estimation or prediction of your SAG Mill’s tonnage; well, there are 3 ways to generate good rock “ore” hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three “religions” of grinding, and there are small-scale tests suitable for all three of the major religions
