Energy Use of Fine Grinding in Mineral Processing ...

Abstract. 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.

Stirred Media Detritors (SMD) -

The SMD utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media/ slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces which produce the desired grinding mechanism for fine grinding.

Grinding Mill Design & Ball Mill Manufacturer

The biggest size is chosen when the mill is used as a primary grinding mill. For fine grinding of e.g. sands, balls can be replaced by cylpebs, which are heat treated steel cylinders with a diameter of 12-40 mm and with the same length as the diameter. Ball mills are often used as secondary grinding mills and for regrinding of middlings in concentrators. Ball mills can be of the overflow or of ...

The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons. Depending on the size range a Vertimill (), a stirred media detritor () or an IsaMill (Xstrata) is typically used. All three use a different motion than a tumbling mill and as a result each has their own laboratory test for scale up. In the case of the stirred media ...
