1. Introduction 1.1. Background. With the continual depletion of high grade simple ore bodies, more complex, finely disseminated ore bodies are being processed, which has led to an increase in the prevalence of fine grinding (Sinnott et al., 2006).This has been evident in the platinum group element (PGE) industry in South Africa, where the Bushveld Complex hosts 70% of global PGE reserves.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Another report from Quebec Mines conference, this time by GREG RASMUSSEN (XT) IsaMill technology was developed from the stirred milling technology of Netzsch Feinmahltechnik in the 1990's for use in the fine grained lead zinc ore bodies of Northern Australia in a drive to bring about a step change in grinding efficiency required to make these ore bodies economic to process.

Technology Development • Technology further developed for coarse grinding. Transfer of IsaMill benefits to coarser grained particles – Improved energy efficiency – Process benefits from inert media • Coarse grinding required large mill with suitable media • Large mill capacity – 3000 litre mill scaled up to 10,000 litres – Motor size from 1.1 MW to 3.0 MW
Eight consecutive grinding chambers, patented product separator and short residence times means the mill constantly delivers sharp product size distribution without external classification. The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding discs.
Grinding Mechanism The IsaMill™ 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 21-23m/s resulting in high energy intensities of up to 300kW/m3. Figure 2 illustrates the layout of the IsaMill™.

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 change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs of fine grinding.
IsaMill™ Grinding Solutions' performs IsaMill™ testing using a Netzsch LM4 mill, which has the exact same internal dimensions and workings as the IsaMill M4. Signature plot testing using the IsaMill™ provides data on the specific energy required to reach product size and can be used in the design of IsaMill™ grinding circuits.
