Laboratory Grinding Mill

By using wide classifiers with high raking capacity, circulating-load ratios are now being carried to 4:1 or higher. The direct result of the increased capacity is reduced power, liner, and grinding media consumption per ton of finished ore. There is, of course, a limit as to how large a circulating load can be carried in practice.

Effect of additives on grinding of magnetite ore

Investigations have been carried out to evolve a grinding aid useful in grinding a 40% iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture. These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite

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.
