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.
Swiss-based STM developed the Vertical Regrind Mill (VRM) and released it to the minerals market in 2012. More than 60 of the stirred media grinding mills have been sold to mines across the Americas, Europe, Africa, Asia and Australia.

NEWS: Vertical Stirred Mill Our newly developed Vertical Stirred Mill designed in conjunction with TSB, MIRO, IMERYS and the University of Birmingham presented at the IMPS2014 - International Mineral Processing Symposium - in Turkey during October 2014 and much more recently at the IChemeE "Particle Technology Special Interest Group" Conference ...
An ever-growing demand for products and technologies that require an increasing supply of minerals can be witnessed globally. At the same time, large deposits are becoming harder to find, ore grades are declining, and water management is a rising concern.That's why you face the challenge of meeting the demand, locking in profits, while also keeping mining sustainable.
Introduction. Mineral Mixing Barrel(Stirring tank) is an indispensable machine which is driven by the motor V-belt drive to drive the impeller to rotate, fully mix the reagent and the ore pulp and increase the reaction time and strengthen the reaction quality of the reagent.
At Abloy we have raised the pinnacle of protection by modifying all our Mining solutions and entire keying systems to be ATEX approved.

Most importantly, the mills are customisable to each unique mining application, optimizing the performance of the mill and recovering more ore for your business. 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:
2.1, Adopting The vertical spiral stirred mill to grinding the gold ore, and the same time leaching operation, can extract gold economically with low cost and high gold recovery. 2.2, Applied for the second stage ore grinding, the fine grinding of sulphide ore and the tailings recycling, could economically grind ore to -400 mesh more than 90%-95.
This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 [ 20 ]. This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s [ 21 ]) vertical pin mill which has been produced in various forms by Union Process since 1946 [ 19 ].

Vertical Linear Motion (VLM) technology was invented and designed to dramatically improve mixing, and to use up to 80% less power to do so. While most conventional mixers use a circular motion to "stir" liquid, VLM Mixers ™ use a vertical motion that not only achieves isotropic mixing, but also extends digester life with significantly reduced energy and maintenance …

The Vertimill® is a vertical stirred mill that uses a helical screw to impart motion in the charge. Mechanically, the Vertimill is a very simple machine with an agitating screw suspended into the grinding chamber, supported by spherical roller bearings, and driven by a fixed speed motor through a planetary gearbox.
