The IsaMill™ is a horizontal, high speed stirred mill that operates with very high power intensities (up to 300kW/m3) compared to ball or tower mills (with less than 40kW/m3). This high power intensity enables the IsaMill™ to process coarse particles to ˜ne product sizes with small media at high throughput.
The scaleup procedures developed for the IsaMill were then compared against the full scale Century - SMD's. The IsaMill M4 procedure accurately predicted the full scale Century performance on a P 80 basis. This is intuitively correct though the mills have different designs (horizontal versus .

For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.

1. 1989-90: Initial stage, regrinding to 15 µm (ball mill, inert media). Evaluation of concentrate quality (marketing study) –must regrind to 7µm. 2. Mid-1990: Purchase of laboratory batch bead mill (i.e. a stirred mill with inert media) with much increased capability. 3. 1990-91: Second stage of laboratory work with regrind to 7 µm.
The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.
