Generally, stirred mills can be divided into two categories; namely, gravity-induced and fluidized charge mills. Commercially active brand names for the gravity induced variety are the Metso VERTIMILL™ (VTM™) and the Nippion-Eirich tower mill. The fluidized stirred mill brands are represented by the Metso Stirred Media Detritor (SMD ...

Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning

Stirred mills are primarily used for fine and ultra-fine grinding. They dominate these grinding applications because greater stress intensity can be delivered in stirred mills and they can achieve better energy efficiency than ball mills in fine and ultra-fine grinding. Investigations were conducted on whether the greater performance of stirred ...

Stirred bead mills, also known as stirred media mills, find application in a number of industries, where they are used for fine grinding of particulates or fine dispersion of agglomerates [1]. In the minerals industries, fine grinding in stirred mills is becoming increasingly important, since available ore bodies are increasingly fine-grained and

The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s. The Metso detritor mill, however, has a maximum tip speed of 11–12 m/s. Even though a finer ground product is obtained with higher speeds, a limit has to be imposed. This is to allow the separation of media and mineral particles at ...

The simplest stirrer geometry is the. Plus de ...

Stirred mills grinding modes are mainly attrition but could be manipulated to include breakage by compression or impact loading. Macro and micro analysis of particle breakage and grinding mechanisms are correlated. Macro analyses convey information that relates grinding mechanism to particle size and shape. Micro analysis on the other hand ...

The units integrate Metso Outotec's comprehensive stirred mills portfolio with other proprietary technology products like hydrocyclones, samplers, analysers, and slurry pumps. To complement this, Metso Outotec can offer a process performance guarantee based on testing of a representative sample, and a TCO calculation co-created with the customer.

Metso Outotec has been a frontrunner in driving stirred milling innovations for decades and is now excited to introduce its comprehensive portfolio featuring three frontrunning stirred milling solutions – Vertimill®, Stirred Media Detritor, and HIGmill™. Ideal for grinding finer products, stirred mills are known for their energy efficiency and compact design, reducing floor …

Stirred mills, like the VXP2500 that New Dawn bought, overcome these problems by using smaller ceramic grinding media – from two to four mm in diameter – while using rotating discs to impart additional energy to the mix. …

Our stirred mill and tower mill solutions offer a range of advantages, designed to optimise your milling while solving a number of issues traditionally related to industrial grinding: Lower capital expenditures; Shorter lead time than …

The stirred mill has an impeller that places the seals and bearings into the batch. The stirrer axis is fitted with five slotted stainless steel shafts and arms. The shaft is driven with a 3 kW motor and runs at between 50 and 3000 rpm and can be used for dry grinding practices. The mill is controlled by a control panel with an energy analyzer.

Transcript Stirred Milling MF2 PGM Flow sheet

Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur.

The figure to the left shows the typical application ranges for ball mills and stirred mill. The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on the ore properties but generally is in the range of 20 to 40 microns.
