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. Overall energy use and media ...
The ball mill operates with 25 mm grinding balls. The operational solid percentage of both mills is between 78 and 80%. Samarco's process team reports a reduction of approximately 30% in specific energy consumption of the Vertimill, when compared to tubular ball mills, for the same grinding job.
Stirred mill is the key solution in minerals processing for fine or ultrafine grinding. Outotec offer a clear regrinding scope and repeatable solution which includes slurry classification, grinding, slurry pumping and particle analysis. Vertimill ® or HIGmill™. MHC™ Hydrocyclone.

VertiMill 3D model. Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine come with a roller (or the ...
The data also showed that the grinding circuit (with a Vertimill for secondary grinding duty) is more energy efficient than a conventional circuit that has a ball mill for secondary grinding duty.
Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.
Media Detritor (SMD) and Vertimill system, both being a vertical mills operating at low tips speeds - < 3 m/s (, 2002; Allen and Ntsele, 2012). In the SMD mixing is generated by grinding pins (Allen and Ntsele, 2012), whereas the Vertimill has a spiral rotor and no stator.
system that enables slurry to exit the mill but prevents the grinding media from leaving the mill (Enderle et all, 1997). Since this time, the ISAMILL® technology has been implemented at several mining operations and undergone further development. The latest development is a 2.6 MW, 10 m3 unit installed

By replacing ball mills in power intensive grinding applications such as grinding SAG mill and HPGR products, the savings that have been experienced in regrind applications can be multiplied further. Typically, the total cost of ownership of the Vertimill® compared with traditional ball mills is 35% less.
