This state-of-the-art full circuit concentrator is based on industry learnings from over 133 IsaMill™ and 420 Jameson Cell installations across 30 years. It has been installed in Philex and New Britannia operations and is soon to be installed in Ozernoye operation, Making it the world's largest Zinc operation.

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. Just as importantly, the processing advantages of inert grinding greatly improve metallurgical performance …

The IsaMill is unlike any other grinding mill1: • It is very high intensity – 300kW/m3, compared with typically 20kW/m3 for ball mills. This means it is easily installed in a small area. ... The internal classifier means simple operation, no screens to block or maintain, and allows low cost natural grinding media to be used (e. g. sand).

Cylindrical shaft spacers are used to separate the IsaMill™ grinding discs. • Alternative conical spacers have now been tested at lab, pilot and full scale. • In an operating IsaMill™, the new configuration reduced specific energy by 13–17%. • Further specific energy savings are possible at finer grind size targets. •

The IsaMill™ reduces the energy, media and capital costs of grinding. It's incredibly effi cient and intense. It˚focuses only on the particles that need grinding. The IsaMill™ …

IsaMill – The IsaMill is a horizontal disc mill, ... Bond ball mill with industrial ball mills; changing to a different type of mill with different geometries, different operating principles and different types of stressing conditions present makes the application of a stirred media mill efficiency factor unlikely to work generally.

At Bain, our Operating Principles have defined how we work and who we aspire to be for more than 30 years. We have refreshed them as needed to adapt to changes in our firm and in the world around us, but they remain remarkably consistent as an expression of the actions and beliefs that power our extraordinary teams and the reason that Bain is …

The very sharp size distribution produced by the IsaMill™ further assists flotation. Minimise circulating loads, and open-circuit as much as possible. If a mineral isn't recovered early, it either needs more liberation or better surface chemistry. Both can be …

IsaMill™ design in the Jameson Concentrator was based on testwork principles that allow for an accurate 1:1 scale up. This paper explores how the M20,000 in particular, and IsaMills™ in general, ... maintenance service area when the mill is in operation. • The IsaMillTM can utilise gland water injected directly into the plant's main ...

Engage your team in a discussion about the sample situations and how they might react based on the draft operating principles. Make changes or additions to the operating principles as needed.

IsaMill™ Operators Get Performance and Maintenance Optimised with IMIS App News update 24 February 2020 . Glencore Technology have transformed their popular IsaMill™ licensees' free maintenance program to a mobile app that allows operations to optimize each mill's performance and maintenance, achieving gains in life of asset, …

OPERATING PRINCIPLES. The grinding discs are spaced along the shaft to agitate the grinding media in a high-shear pattern. When an IsaMill is operated at its optimum media load of 70 to 80 percent filling, the grinding discs in the horizontal layout along the shaft effectively create grinding chambers in series between each disc.

Installations at Lonmin Platinum and Anglo Platinum are examples where the IsaMill was chosen for coarser grind applications because of the flotation benefits of inert grinding. The case study of the Anglo Platinum tailings retreatment plant shows that the 2.6MW mill was the enabling technology for the operation.

IsaMill™, typically, consists of a series of uniformly spaced identical disks mounted on a rotating shaft which is encased in an outer shell. The mill offers high …

IsaMill operation also has a response to solid conte nt of the milling enviro nment. Jankovic [3] reported that the performance of the mill improves when operated at a denser.

During IsaMill™ operation, the IsaMill™ power draw slowly decreases due to grinding media wear. For each stage of testwork, top-up grinding media was added by addition into the feed pump box to be pumped into the IsaMill™ with the feed slurry. Adding the top-up grinding media, following initial start-up and stabilisation, ensured that, as ...

Operating principles can be informed by core values. For example, if customer satisfaction is a core value, a team operating principle might be, "We respond to each other's requests within 24 hours." Fort Wayne Metals separates values from operating principles in the following way: Values. Our people are the source of our …
