Stirred Media Detritor SMD is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a highenergy motion to the media and slurry mixture inside the mill. This results in particletoparticle shear and compressive forces that produce the desired grinding mechanism for fine grinding. Lower capital cost.Get Price
Agitated media mills stir the grinding media to break down the target material into ultrafine 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. The choice of a suitable mill
Technology Development Technology further developed for coarse grinding. Transfer of IsaMill benefits to coarser grained particles Improved energy efficiency Process benefits from inert media Coarse grinding required large mill with suitable media Large mill capacity 3000 litre mill scaled up to 10,000 litres Motor size from 1.1 MW to 3.0 MW
significantly increasing grinding efficiency. 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. NapierMunn et al., 2005. In stirred mills there are no freefalling possibilities for grinding media, meaning that
The system is designed to allow changes to the distribution of the media and energy within the mill by changing the number and spacing between the impeller discs. MillingCommunication Process . The mills are designed to run at tip speeds between 10 and 15 ms and are capable of operating with very dense grinding media.
2 2 grinding media 1 mm on wet grinding of talc d 506 m powders to produce submicron particles was performed in a labscale 750 ml stirred media mill. Experimental results were evaluated based on the average particle size d 50, specific energy consumption kWht reduction ratio and the specific surface area m2gr.
The Outotec HIGmill is a vertically oriented stirredmedia grinding mill. Taking advantage of gravitational forces and Outotecs GrindForceTM rotor technology, it uses fine grinding media to
Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.
Ceramic grinding media reduces vertical mill component wear and maintenance costs for mining company. CARBOGRIND high performance ceramic media significantly improves grinding efficiency, lowers mechanical equipment wear and reduces media replacement costs the company sought to optimize production processes at the Metso stirred media
Stirred mills amp Tower mills simple, effective and cost efficient As lower ore grades and complex mineralogy are driving demand for more efficient fine grinding, you can depend on FLSmidth for a full range of finegrinding mills designed for easy shipment, simple erection and troublefree maintenance.

Extensive work has been done by Kwade and Schwedes 29 to gain fundamental insight into all the different aspects of wet grinding in stirred media mills. The stress model was developed to better
suitable and economic grinding media initially low cost media have been employedsized silica or river sand and granulated furnace slag. This is now becoming more uncommon with ceramic grinding media of various compositions being generally employed. Efficiency of operation, stirred mill type, and quality control are important factors in this
The company supplies to all major stirred media milling technologies in the mining and minerals industries. The diversity and performance of our full product range provides the best solution to any ceramic grinding media requirement.
coefficient as a new tool in characterising stirred milling grinding media. The first application of this ceramic media will be regrinding a gold bearing, pyrite rich sulphide flotation concentrate in the industrys largest stirred mill the M10,000 IsaMill. 1 INTRODUCTION The high energy efficiency of stirred mills
selecting grinding media size, denisty of grinding media, and mill speed to approach an optimum stress intensity and maximize the stress number. Due to Kwades investigations and modelling of grinding and dispersing with stirred media mills, the following milling tests with calcium carbonate and different grinding media

Media Selection Optimisation. Utilising the facilities at the UFG Metallurgical Laboratory Keramos can undertake detailed studies investigating the optimisation of ceramic grinding media product selection relevant to customers specific milling technologies duties and ore types.
In the mining industry, ultrafine grinding is required to increase recovery yields, liberate trapped grains and create new active surfaces. The stirred mill environment is particularly severe. The minimum requirement of a bead is to be competent and provide a costeffective, energyefficient grinding solution. A competent media type must be
stirred media mills are still in an early to intermediate stage of development. A classic factor in a time approach can lead to the failure to identify and connect basic and interaction impacts and optimize grinding parameters 21. To date, a lot of studies have been carried out to produce ne and ultrane materials in a stirred media mill.
ceramic media, known as Keramax MT1TM for the mineral processing industry. This paper will present a description of the Keramax MT1TM media and industrial results from various users within the Anglo Platinum group since the first stirred mill using ceramic media was commissioned in November 2006.
