Stirred mill is the key solution in minerals processing for fine or ultrafine grinding. Fruitful Outotec offer a clear regrinding scope and repeatable solution which includes slurry
This method has found a widespread application for simulations of industrial processes involving granular media, such as for wet stirred mills [26, 27], tumbling mills [20,23], and
The present work on modelling breakage in stirred mills took as its starting point the population balance model originally developed for ball mills (for example Reid,

In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry. There are several advantages
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 Fruitful 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
Davey: The Fruitful Outotec stirred mills are suitable for a large range of product sizes. The standardized range includes chamber units of up to 50,000 liters and the world’s largest industry
The wet fine grinding experiments were performed in a vertical stirred mill. Four significant operating variables stirrer speed, grinding time, feed size, and solids concentration were investigated for their effect on the performance of stirred mills. The performance of the mill was assessed in terms of achieving small product size at lower
介质搅拌式磨机 (SMD)是一种流化立式搅拌磨机，用于高效生产细粉和超细磨矿产品。. SMD的典型给料粒度为100µm及以下，通过率80%，但也可在各种应用中处理较粗的物料。. SMD具有开路和闭路回路中连续满负荷运行的能力，且产品无钢污染。. 了解有关介质搅拌式
The article deals with an innovative approach of combining modern simulation techniques with pilot plant testing work with the target to develop a new stirred media grinding mill. With the help of discrete element simulation various mill configurations were studied. The target was maximizing the interactions between beads and the related
minerals from refractory ores. Stirred mills have already been reported as an enabling technology for the processing of fine grained ores in lead/zinc applications (Pease, Young and Curry, 2005). Historically, conventional ball mills were unable to economically grind material fine enough to produce the required recovery or concentrate
These features distinguish stirred mills as fundamentally different from both ball mills and Tower Mills, as demonstrated by Tables 1 and 2. Table 1 : Typical Power Intensities of different Grinding Devices Table 1: Power Intensity of Different Grinding Devices Ball Mill is a 5.6m D x 6.4m L @ 2.6MW Tower Mill is a 2.5m D x 2.5m L @ 520KW
Another type of highenergy mill which is considered effective for MA is stirred media mill [32,33]. Effectiveness of such mills for MA of various materials has been reported [34][35] [36] .
This method has found a widespread application for simulations of industrial processes involving granular media, such as for wet stirred mills [26, 27], tumbling mills [20,23], and other large
Better liberation of mineral layers was achieved, compared with a ball mill and a rod mill. Through regrinding with the stirred mill followed by a twostage cleaning flotation process, a lowgrade graphite concentrate containing 84.59% fixed carbon could be refined to a highquality concentrate containing 98.62% fixed carbon with a graphite
Stirred mills & tower mills for efficient customised application. For fine and ultrafine grinding, stirred mill and tower mill technology provides efficient solutions to meet your needs. These mills operate at power intensities

Stirred Media Detritors (SMD) Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open and closedcircuit
Fine grinding is becoming an integral part of mineral processing plants to liberate valuable minerals from finegrained lowgrade ore bodies. Stirred mills are becoming recognized by the industry as a more efficient technology selection compared to the ball mill for fine grinding (< 100 µm). The increasing number of stirred mill installations in mineral
Through regrinding with the stirred mill followed by a twostage cleaning flotation process, a lowgrade graphite concentrate containing 84.59% fixed carbon could be refined to a highquality concentrate containing 98.62% fixed carbon with a graphite recovery of 94.15%. It is demonstrated that the stirred mill is more suitable for selective
Stirred media mills are used in numerous industries because of their high energy efficiency, fine and ultrafine grinding ability, and reduced contamination. In view of their growing importance, basic research on power characteristics of stirred media mills has been carried out [1,2]. In this research, the torque required to rotate impellers
CITIC HIC's vertical stirred mills are widely used in nonferrous metal, black coal and chemical mines for domestic mining companies and concentrators, and have been exported to Australia, Chile, Russia and more countries and regions all over the world. The reliable performance is particularly appreciated by our customers worldwide.
