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 …

It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: Work index, W i; Largest particle size and size distribution; Density of solids and slurry ... For wet ball mills, Bond expressed power draw as a function of the total mass of media:Pâ†"M / Mâ†"B – 15.6Φâ†"V ...

For comparison, a batch ball mill 300 mm (D) × 300 mm (L) installed at JKMRC pilot plant was employed to wet grind the same ore samples as the IsaMill. ... This evidence supports that, unlike the relatively versatile ball mill, the IsaMill needs to be optimised in its design and operational conditions to suit a specified grinding duty.

I think the original question does not refer to wet or dry milling, so we have wet vertical ball mills and wet horizontal ball mills and dry vertical ball mills and dry horizontal ball mills. Even Balls is a general term, cylpeps, steel balls, beads etc. are used in ball mills and some mills which use balls are not called ball mills

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The IsaMill is a horizontal stirred mill with sizes up to 3 m3 chamber net volume and 1120 kW installed motor. It was jointly invented by Mount Isa Mines of Australia and Netzsch …

In addition to differences in operating conditions, the feed material influences the n exponent value; Shi et al. [91] used a lab scale IsaMill to grind four sources of ore from different areas of ...

How it works. Eight consecutive grinding chambers, patented product separator and short residence times means the mill constantly delivers sharp product size distribution without external classification. The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding discs.
