Grinding is by attrition and abrasion of the particles in contact with the high speed, small, circulating media. This breakage mode produces very fine sized particles at relatively low power consumption. IM grinding mechanism v2.jpg. At the discharge end of the IsaMill™, slurry and media reach the patented product separator.
1. Introduction. IsaMill is a horizontal high speed stirred mill that operates with very high power intensity. It has been increasingly used in the mineral industry for fine and coarse grinding, because of its high energy efficiency compared with other conventional grinding techniques (Gao et al., 2001).Inside the shell, there are rotating grinding discs mounted on a shaft, which is coupled to ...

Silica sand grinding mill . While most grinding in the mineral industry is achieved using devices containing a steel grinding medium the isamill uses inert grinding media such as silica sand waste smelter slag or ceramic balls. the use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore.
To see a world in a grain of sand, And a heaven in a wild flower, Hold infinity in the palm of your hand, And eternity in an hour. A robin redbreast in a cage. Puts all heaven in a rage. A dove-house fill'd with doves and pigeons. Shudders hell thro' all its regions. A dog starv'd at his master's gate.

1.. IntroductionIsaMill is a high-speed stirred mill developed by Mount Isa Mines (Xstrata) in Australia for fine and ultra fine grinding at an industrial scale paring with the conventional grinding mills such as ball mills and tower mills, IsaMill can significantly reduce comminution circuit energy cost and grind mineral particles to as fine as 7 μm, .
AG or SAG mill, intermediate grinding to a ball mill or tower mill, and fine grinding to a stirred mill such as an Isamill or Stirred Media Detritor (SMD). Of course, various exceptions to these typical values can be found. In fine grinding, a material with an F80 of less than 100 lm is comminuted to a P80 of 7 to 30 lm. (P80s of
Grinding media types Until 2005, all IsaMill installations have taken advantage of the technology's ability to use low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill scats (autogenous milling). Whilst the IsaMill produces high energy efficiencies
Tough economical conditions and high grade but fine-grained ore processing have forced the mining industry to look for more efficient processes. IsaMill Technology for ultra-fine and fine grinding is one such process employed at several mining operations in Australia including Mount Isa Mines Limited in Australia. Mount Isa Mines is a business unit of MIM Holdings Limited. MIM is an Australian ...

In short, IsaMill™ reduces the energy cost, media cost and capital cost of fine-grinding. The IsaMill™ is used extensively in base metals, PGM, gold processing and magnetite grinding applications. And the power capacity of an IsaMill™ ranges from 75kW to 3.8mW. IsaMill™ is the real-world specification of choice in: mainstream grinding.
1.1 Grinding Media Types To date, all IsaMill installations have taken advantage of the technology's ability to use a low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill scats (autogenous milling). Whilst the IsaMill produces high energy efficiencies
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. 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 ...
