Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.

Fine grinding is a relatively new area and considers grinding below 30 μm down to around 10 μm. Below 10 μm, the term "very fine grinding" can be used. The energy consumption in ball milling rises sharply for grinding products below 75 μm and below 30 μm grinding using ball mills becomes uneconomical.

Stress imposed on particles is result of the centrifugaI forces of grinding media being agitated at high speed. In this situation stress intensity is proportional to the cub of media size, stirrer speed velocity squared and the difference between the media and slurry density (Kwade, 1996). In low speed vertical stirred mills (LSV) such as the ...
