Stirred vertical mills improve copper concentrate regrinding. The 2 245-kW stirred vertical mill, Vertimill, manufactured by minerals and metals processing equipment manufacturer Minerals improves the regrinding process of ….
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 …
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.
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.
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 …
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.
In low-speed vertical stirred media mills, gravity forces also take action [11,34]. Centrifugal forces become more important at high stirring speeds (i.e. a tip speed of >3 m/s) in a pin type ...
This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s ) vertical pin mill which has been produced in various forms by Union Process since 1946 . Several other stirred media mill designs have been developed over the subsequent decades, with the most common types used in the mining industry introduced below. •

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 …
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.
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.
Grinding mill developer, Swiss Tower Mills Minerals has been awarded an order for the delivery of one VPM10 vertical stirred grinding mill for the Navachab gold mine plant expansion. The company's scope includes the design and delivery of one Vertical Power Mill VPM10 grinding mill, a vertical ...
At present, vertical stirred mills are increasingly employed at industrial scale. The regrinding process characterization requires mixing regime knowledge along with the …
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 Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. The...
Stirred media mills have been increasingly used in ultra fine grinding The VXPmill is a vertical high speed stirred media mill for grinding mineral ores with high efficiency Since it is a new technology in the industry there is little understanding on the breakage kinetics of the mill.
JM series stirred ball mill is a kind of high efficiency ultrafine ore grinding equipment (also called tower mill or vertical spiral stirred ball mill), mainly adopted for the ultrafine grinding test research, also for the small scale industry …
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.
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 are now widely used in the minerals industry and the increasing variety of models from different manufacturers and number of new units installed worldwide are evidence of ...
The popularity of stirred media mills has risen in recent times. CITIC HIC has developed our own range of vertical stirred media mills to complement our conventional grinding mills range, research and development team in Australia and CHina constantly working improving technology and efficiency of the machine.
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.
