26 years 51 technical papers 9 minerals IsaMill™ uses horizontal milling to secure better energy efficiency, product size and availability The IsaMill™ has realworld success in 143 metalliferous installations across 23 The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput 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 The mixing chamber is filled with the grinding medium (normalIsaMill
IsaMill Technology Used in Effecient Grinding Circuits
The IsaMillTM is a horizontally stirred mill consisting of a series of 8 discs rotating around a shaft driven through a motor and gearbox The discs operate at tip speeds of 2123m/s The year 2019 marked 25 years since the first commercial installation of the IsaMillTM, and today there are over 130 installations totalling 230MW of installed power, positioning the The IsaMill™ 25 Years of Stirred Milling Glencore Technology

Improving IsaMill™ energy efficiency through shaft spacer
The IsaMill™ addressed the two major issues of energy efficiency and the resultant downstream metallurgy, primarily through the use of stirred, small, inert grinding media The first 11 MW IsaMill™ using inert media was commissioned at Mt Isa in 1994 and four 11 MW IsaMills™ became the enabling technology for the McArthur River Contribute to jidafang2022/en development by creating an account on isamill grinding in the cement industry

, the IsaMillTM produced the finest P 98 This P 98 /P 80 ratio is an excellent indication of how sharp the feed sizing is, ie the closer to 1, the sharper the cut, and its amenability to leaching duties (Clark and Burford, 2004) This is why the IsaMill™ was selected for the Albion Process™ 23 ScaleUp to the M10,000• TM The media hopper has been repositioned from under the IsaMill to the side Due to the backpressure created from the rotor, it was possible to utilise this action to pump media out of the IsaMillTM to a media storage tank/hopper during its maintenance shutdown sequence rather than discharging TMto the hopper below the IsaMill Stirred Milling Design Incorporating the IsaMill™ into the Jameson
