    Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

  • Mill (grinding) - Wikipedia

    Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry.

    (Stirred mills can produce product down to 7 microns). A comparison chart for grinding a pyrite concentrate with a ball mill (9 mm balls) and a stirred mill (2 mm sand) shows a decrease in net energy from about 44 to 24 kWh/tonne when producing a 20 micron product and going from about 80 to 30 kWh/tonne when producing a 15 micron product.

  • IsaMill - Wikipedia

    The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

  • Ball, Vibratory and Stirred Mills - How they Work

    Media mills operate by having energy transferred to the media which in turn grinds the feed material in a packed bed. Regardless of the mill type, the media energy density per unit surface area is constant. Since for optimum grinding conditions, both peak pressures and particle number of the bed depth are constant, the frequency of energy input is inversely proportional to feed size.

    which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2” or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
