HIGmill high intensity grinding mill - Metso Outotec

The HIGmill comprises a mill body, shaft with grinding discs, shell mounted counter rings, gearbox, and drive. The grinding chamber is filled up to 70% with grinding beads. Rotating discs stir the charge and grinding takes place between beads by attrition. The number of discs (grinding stages) depends on the application and can be as high as 20.

Ro-Star™ Vertical High Intensity Ultra-fine Grinding Mill ...

The Ro-Star is a suspended, vertical high intensity wet grinding mill with a vertical drum and rotor-stator grinding disc mechanism. Hence the name “Ro-Star” The mill body consists of a shell equipped with internals that are in a specially designed segmented disc arrangement and then an agitator shaft with a similar arrangement. The rotor-stator configuration has been developed with flexibility in mind.

Stirred Milling Technology – A New Concept in Fine Grinding

In stirred media grinding, the energy intensity (kW/m³) is very high versus tumbling mills. In the HIGmill the power intensity (installed) is typically 180 to330 kW/m³. This means a very “packed” process: i.e., high throughput and/or high SGE in a small unit. Energy efficiency/fineness vs. SGE is far better in fine grinding than in tumbling mills (Figure 4), as the finer the product, the greater the energy saving.

VXPmill for fine & ultra fine grinding | FLSmidth

The mills are designed to run at tip speeds between 10 and 15 m/s and are capable of operating with very dense grinding media. The result is a power intensity that is higher than the low-speed mills and overlaps that of the high-speed mills.

Stirred media mills in the mining industry: Material ...

Jun 01, 2020 · The tip speed of the lab mill is run at around a third of the industrial IsaMill, meaning that maximum stress intensity SI GM is six times higher for the latter ; at least some of this is because smaller mills have narrower stress intensity distributions, leading to a lower median stress intensity for a given value of SI GM , as discussed in the stress intensity theory section.

Semi Autogenous Grinding Mill - an overview | ScienceDirect ...

Ball mills have traditionally been used for fine grinding of minerals, and in these cases smaller ball sizes than in conventional grinding are used to increase contact area and decrease collision intensity [15], and lower mill speeds are used to cause the media to cascade rather than cataract, shifting the typical forces experienced from impact ...
