Media stress intensity analysis developed for high-speed horizontal mills was modified to include the effect of gravitational force in the vertical stirred mills such as the Tower and SAM units. The results suggest that this approach can be successfully applied for both mill types. For a given specific energy input, an optimum stress intensiO ...

The vertical stirred mill employed saved about 4 million kWh/year in electrical energy, reducing annual operating costs by about $325,000. Larger horizontal stirred mills were later installed at the Embako mines in BC. Ball mills are often used to grind feedstock into particles of 30 to 100 microns in size.

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

The use of vertical stirred mills in the mining industry has increased remarkably over the past few decades as a result of the growing demand for finer ore grinding. This equipment is recognized to deliver higher energy efficiency in fine grinding operations when compared to conventional tubular mills.

The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in …

Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.

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.

Outotec leads stirred milling innovations and continues to be the industry standard in performance. We offer a wide portfolio of stirred milling technologies: Vertimill ®, HIGmill™, and Stirred Media Detritor (SMD).. Outotec stirred mills are part of the Planet Positive product portfolio, which apply the mill input energy to liberate mineral in a sustainable manner.

The stirrer vertical mills are designed such that they are either gravity induced or fluidised beds [2]. The gravity induced mills, known commercially as Vertimill, use the rotational movement of screws to provide the size reduction forces while the fluidised bed mills use the rotational forces due pins.

Stirred media mills are relatively new to mining industry, and several new technologies have been developed such as the VXPmill (vertical stirred mill). There is little technical understanding of optimizing and scaling-up of the VXPmill. This thesis addresses both of these issues and therefore supports commercial applications of this vertical stirred mill. Stirred media mills …

Swiss Tower Mills Minerals (STM), headquartered in Baden, Switzerland, is known for having successfully translated the vertical stirred milling technology of industrial minerals to hard rock minerals processing. It recently became a sponsor of the non-profit Coalition for Eco-Efficient Comminution (CEEC).

Swiss Tower Mills Minerals AG (STM) has been awarded an order for the delivery of one VPM10 vertical stirred grinding mill for the Navachab gold mine plant expansion in Namibia. The project was awarded in fourth quarter 2020. The successful Factory Acceptance Test (FAT) was carried out in Villach, Austria in the third quarter 2021.

Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. 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.

Stirred milling technologies have firmly established themselves in concentrator circuits as energy-efficient alternatives to tumbling ball mills. High and continued increases in electricity costs, coupled with the ever-increasing power consumption by primary grinding circuits due to declining head grades of ore-bodies, provides a compelling case for these technologies.
