Grinding - Grinding | Isamill
Media recirculates between the rotating discs distributing grinding action throughout the IsaMill™. 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.
Open Circuit Configuration - IsaMill™ Advantages | Isamill
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.
IsaMill - WikiMili, The Best Wikipedia Reader
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.
Ultrafine Grinding and the IsaMill™ Technology - About ...
The IsaMill™ uses inert ceramic grinding media ranging from 1.5 mm to 6.0 mm, that produces clean, polished mineral surfaces resulting in improved leaching kinetics. A steep particle size distribution is produced in the mill. The 98% passing size in the mill is typically less than 2.5 times the 80% passing size, and very little coarse ...
IsaMill™ - Grinding Solutions Ltd
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.

dramatically increases the grinding surface area and the number of grinding “events”, essential to efficiently grind fine particles. Figure 1 shows the grinding power required to grind a sample of KCGM pyrite concentrate to different target P80 grind sizes, using a ball mill (with 9mm steel media) or an IsaMill with sand media.
Fine grinding—Developments in ceramic media technology …
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).
Energy Use of Fine Grinding in Mineral Processing ...
Dec 18, 2013 · 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.

Grinding pyrite isamill
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.
