    01/01/2016· Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world. Mill sizes up to 13.4 m diameter are considered feasible with current technology . The largest volume mill in the world

    Autogenous Mills, How Do They Work? Mine Engineer.Com

    Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media. The grinding is facilitated in autogenous mills by attrition with limited grinding by impact. For an ore to successfully grind autogenously, the ore must be competent, and it must break along grain boundaries at the desired product size

    Autogenous mill, Ag Mill, Semi-autogenous Mill, Ball Mill

    The working principle of the autogenous mill is almost the same as that of the ball mill. The difference is that the barrel body of the autogenous mill is larger, which does not use steel balls or any other grinding medium. The efficient autogenous mill uses the crushed material in the barrel body as the grinding medium, which continuously impacts and grinding to achieve the purpose of grinding.

    Predicting the specific energy of autogenous and semi

    01/03/2004· A rock breakage test has been developed that can help predict autogenous (AG) and semi-autogenous (SAG) mill performance in situations where only limited quantities of rock samples are available. The test was originally developed to make use of quartered (slivered) core but whole core, half core and lump material can also be used. Original core diameters in the range 27–85 mm are suitable

    SAG Mill Testing Test Procedures to Characterize Ore

    the JKMRC approach to autogenous mill characterisation was to separate impact and abrasion mechanisms into two different tests (drop-weight and abrasion tests). Equally important is the need to represent, approximately, the correct size reduction in a comminution device. Because grinding theories are imperfect and ore hardness can vary with size, grindability tests are designed to best

    Semi-autogenous grinding (SAG) mill liner design and

    Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These actions apply crushing, attrition and abrasion

    Ball mill Wikipedia

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the
