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 (normalgrains, to gold that is in solid solution with the sulphide matrix Techniques used to recover gold different types of fine grinding mill The IsaMill was the most efficient of the two IsaMill Ultrafine Grinding for a Sulphide Leach Process
The IsaMill is a horizontal high speed stirred mill that operates with very high power intensities (up to 350 kW/m3) In comparison, the power intensity of a ball mill is about The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling The IsaMill was developed for fine grained orebodies that needed a step IsaMill NETZSCH Grinding & Dispersing

At full scale, by varying the IsaMill™ throughput (at standard operating mill speed) it was demonstrated that a reduction in specific energy was observed of approximately 13% at a P 80 target grind of 22 µm increasing to 17% at a P 80 target of 18 µm There was an accompanying decrease of about 22% in drawn mill powerThe IsaMill™ typically operates around 70% media filling volume As the shaft rotates, the grinding discs agitate the media such that it is centrifuged outalong the face of the discs towards the shell liner As it reaches the shell liner, the media is redirected back towards the mill shaft areaImproving IsaMill™ energy efficiency through shaft spacer
The IsaMill™ was used to ultrafine grind about 10 t/h of pyrite flotation concentrate to 1012 µm prior to gold cyanide leaching Based on the success of the Gidji installation, another was installed at the processing plant at KCMG’s Fimiston operation in 2002 in a similar dutyConsidering 720 running hours at 24 hours a day can need just 8 hours maintenance in a month, it can easily deliver 98% availability from a mill that’s easy to open And recent developments like conical spacers have improved performance by reducing the energy needed to grind by up to 22% “The IsaMill has evolved a lot in 25 years”, saidJV Article: IsaMill Leaps Into Small Footprint and Big Performance

This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget Overall energy use and media use are strongly related to stress intensity, as well as to media size and qualityFirstly, the IsaMill has been redesigned to reduce civil infrastructure costs by up to 28% Secondly, a new 1,6002,200kW ‘M7500' model has been introduced to sit between the M5000 and the M10000 models According to the company, the two changes are intended to achieve significant savings for clients and to meet a gap in Glencore Glencore Technology redesigns IsaMill, adds new model
