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 ).
12%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 quality.
One of the features of the IsaMill operation is the minimization of super fines, i.e. < 5 microns, due to the low average particle mill residence time and enhanced attrition grinding action. The preferential grinding at the coarse end of a typical feed stream particle size distribution is beneficial. The use of inert grinding media—ceramics as
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).
applications for mainstream grinding and concentrate grinding are the subject of a group-wide research and development programme. The first 10 000-litre 2.6 MW IsaMill was jointly developed by Anglo Platinum, Xstrata Technology and Netszch for installation at the Western Limb Tailings Re-treatment project in Rustenburg, South Africa.
It is claimed that the IsaMill can efficiently grind minerals to below 10 microns. The grinding media that can be used include granulated slag, river sand, or a sized portion of the ore itself. Vibrating mills:-The motion is imparted to the charge by the vibratory motion imparted to the shell. The vibration can be generated by springs ...
A method of grinding a mineral-containing ore, which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is …
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput 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.

It is a very thin cup-style grinding wheel which permits grinding in crevices and slot. Saucer Grinding wheels: Saucer Grinding Wheel is an exceptional grinding profile used for grinding twist drills and milling cutters. This finds wide usage in non-machining areas, as these saw filers are used by saucer wheels to maintain saw blades.
IsaMill Wikipedia. While the IsaMills at Mount Isa were operated using screened copper smelter reverberatory furnace slag as the grinding medium, those at McArthur River used screened primary grinding mill fines as the grinding medium for the first seven years of their operation and, in 2004, switched to
A sand mill is a piece of industrial equipment designed to grind a given material into very small particles of roughly equal size. Sand mills are used for processing a wide variety of products, and can also be used as mixers and dispersants, creating a uniform mixture of several components during the grinding process.
Isamill Fine Grinding Technology And Its. IsaMill is a major development in grinding technology jointly invented by Mount Isa Mines of Australia and Netzsch Feinmahltecknik of Germany for ultra fine and fine grinding duties in the minerals industry The IsaMill was introduced by MIM over a period of 9 years as there.

IsaMill™ operations can take advantage of this feature, which translates to an 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). This means low media cost, with power efficiency still better than conventional grinding.
"The IsaMill was developed for fine-grained ores that required at least double the grinding efficiency of ball or tower milling to be economic. This was achieved, but in practice, the benefits of using inert media (eg sand, slag, ore, ceramic) have proven to be at least as important as the higher grinding efficiency.

feed for the IsaMill. Because of the low grade of nickel in the Turnagain project, the composition of mine waste rock and whole ore should be similar, allowing 06-110 to be con-sidered as mine waste rock. 2.2. Grinding tests The laboratory grinding tests were conducted using a 4-L IsaMill (Netzsch, Germany). The IsaMill is a horizontal
Third, grinding in an inert attritioning environment like an IsaMill increases fine flotation rates by producing clean mineral surfaces. An excellent case study is the installation of IsaMills in the Mount Isa lead zinc concentrator to grind lead and zinc rougher concentrate to P 80 of 12 μm and zinc cleaner tailings to 7 μm.
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.
