Ball Mills and stirred mills are applied across a wide range of applications but for each ore there is optimum efficient range The figure to the left shows the typical application ranges for ball mills and stirred mill The Vertimill is always more efficient than a ball mill with energy savings ranging from 30 to greater than 50 The transition point from the Vertimill to an SMDIsaMill

IsaMill Wikipedia The IsaMill is a stirred medium grinding mill in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high throughput mills such as ball mills and rod mills Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill

Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns Below 30 microns the advantages of a horizontal stirred mill become dramatic and below a certain point the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption

High Energy Ball Milling In discussions on high energy ball milling the more generic term ball mills is often used in place of the terms stirred ball mills or Attritors but the differences between the types of mills are quite distinct

A study on the effect of process parameters in stirred ball mill An experimental study on the fine grinding of calcite powder d50 6216 m using a 075 l laboratory stirred ball mill has been carried

Stirred milling What is a stirred mill 4 A mill by which the charge is agitated with stirring mechanisms within a static mill shell Vertical or horizontal The two distinct type of stirred mills gravity induced and fluidized Stirred mills are generally recognized as cost saving technologies through Higher energy efficiency

In Mineral Processing Design and Operations Second Edition 2016 1024 Operation of Vertical Mills 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

Stirred mills are used for wet grinding Ideal for grinding finer products stirred mills are known for operational efficiency and smaller required floor space Metso offers both gravityinduced and fluidized technologies in Vertimill and Stirred Media Detritors SMD allowing for the optimum equipment solution for your circuit

The VXPmill is a vertically oriented stirred media mill that is open to the atmosphere They are designed with a modular impeller that has removable discs and spacers Slurry enters at the bottom travels upward through the mill chamber and overflows through a media retention screen at the top

Tumbling ball mills are capable of fine grinding to around 20 m with the energy efficiency increasing with decreasing media size depending on the feed size For feed sizes P80 of 55 and 100 m Partyka and Yan 15 showed an increased efficiency with decreasing steel ball size from 36 to 55 mm in a ball mill

This quantity is small compared to the power used by a semiautogenous mill and a ball mill in a primary grinding circuit a ball mill can have an installed power of up to 15 MW while installed power for a SAG mill can go up to 25 MW However the energy used for ne grinding is still signicant

Figure 101 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

al 2005 In stirred mills there are no freefalling possibilities for grinding media meaning that impact action does not occur The bead size is small typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range where ball mills are not effective or cannot reach P80 10 to 40 m

Stirred mills 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

Lab stirred ball mill mainly consist of jar with inner grinding media stirring device and other auxiliary devices such as recycling device cooling device timing device speed adjusting controller and etc

Regrind Mills Challenges of Scaleup Michael Larson1Greg IsaMill The standard Bond Mill test applies for coarser ball milling but is not appropriate for stirred milling with fine media grinding to

several studies on stirred ball milling 2 3 4 it was reported that the fineness of the product remains the same for a given energy input regardless of the mill size and the operating conditions If this is true scale up of a stirred ball mill should be quite straightfor

Unlike traditional ball mills collisional energy in stirred mills is not lost by highintensity impacts between the grinding media and the equipment internal walls Hoyer 1984 Jankovic Morrel

Gravityinduced stirred GIS mills include the Tower mill produced by Nippon Eirich and the Vertimill produced by Metso Grinding to below 40 lm in GIS mills or ball mills is usually not recommended In their product literature Metso give 40 lm as the lower end of the optimal P80 range for Vertimills6 At lower product sizes
