The use of vertical stirred mills in the mining industry has increased remarkably over the past few decades as a result of the growing demand for finer ore grinding.
The principal method of grinding in a Tower mill is attrition (scrubbing of particles off material being ground), with the possibility of some shearing and compression breakage taking place due to the motion of the media charge created by the rotation of the helical screw enhancing the media pressure. The Tower mill is filled to a level with grinding media until developed power equals 80% of ...

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.
For the optimization of the grinding energy by the milling parameters Kwade and Schwedes introduced the so-called stress model (Kwade, 1999; Kwade and Schwedes, 2002) for stirred media mills under wet grinding which can be described by the Stress Intensity (SI) and Stress Number (SN) . The basic idea or principle of the product-related stress ...
