Amount of power a particular mill and circuit imparts to the ore.By iteration, the mill size is determined such that it provides enough energy to break the ore to the desired product size.Power draw, step 1 the power required by the ore to achieve a desired size is estimated using the standard bond ball mill work index from a testwork program.

Grinding Test For Iron Ore Tertiary Grinding

Produce performance graph which covers the target sge specific grinding energy, kwht range producing target particle size p80 andor p50, m.4.Before the first sampling round the mill is operated with higher rpms for 10 minutes and then dropped to the desired rpm.With the correct rpms the mill is.

Energy Use Of Fine Grinding In Mineral Processing

Fine grinding, to p80 sizes as low as 7 m, 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 mills energy budget.

Accurate Scale Up Isamill Advantages Isamill

So while your plant or laboratory is the best place to prove the liberation and process advantages of an isamill, once you have selected your target grind size the final mill scale up work should be done in an authorized isamill laboratory, using our standard mill and measuring equipment.This has been proven to give accurate scale up.
